+@section Erstellung aus dem Git
+
+Wenn Sie an Guix selbst hacken wollen, ist es empfehlenswert, dass Sie die
+neueste Version aus dem Git-Softwarebestand verwenden:
+
+@example
+git clone https://git.savannah.gnu.org/git/guix.git
+@end example
+
+Wenn Sie Guix aus einem Checkout erstellen, sind außer den bereits in den
+Installationsanweisungen genannten Paketen weitere nötig
+(@pxref{Voraussetzungen}).
+
+@itemize
+@item @url{http://gnu.org/software/autoconf/, GNU Autoconf};
+@item @url{http://gnu.org/software/automake/, GNU Automake};
+@item @url{http://gnu.org/software/gettext/, GNU Gettext};
+@item @url{http://gnu.org/software/texinfo/, GNU Texinfo};
+@item @url{http://www.graphviz.org/, Graphviz};
+@item @url{http://www.gnu.org/software/help2man/, GNU Help2man (optional)}.
+@end itemize
+
+Der einfachste Weg, eine Entwicklungsumgebung für Guix einzurichten, ist
+natürlich, Guix zu benutzen! Der folgende Befehl startet eine neue Shell, in
+der alle Abhängigkeiten und Umgebungsvariablen bereits eingerichtet sind, um
+an Guix zu arbeiten:
+
+@example
+guix environment guix
+@end example
+
+In @xref{Aufruf von guix environment} finden Sie weitere Informationen zu
+diesem Befehl. Zusätzliche Abhängigkeiten können mit @option{--ad-hoc}
+hinzugefügt werden:
+
+@example
+guix environment guix --ad-hoc help2man git strace
+@end example
+
+Führen Sie @command{./bootstrap} aus, um die Infrastruktur des
+Erstellungssystems mit Autoconf und Automake zu erstellen. Möglicherweise
+erhalten Sie eine Fehlermeldung wie diese:
+
+@example
+configure.ac:46: error: possibly undefined macro: PKG_CHECK_MODULES
+@end example
+
+@noindent
+Das bedeutet wahrscheinlich, dass Autoconf @file{pkg.m4} nicht finden
+konnte, welches von pkg-config bereitgestellt wird. Stellen Sie sicher, dass
+@file{pkg.m4} verfügbar ist. Gleiches gilt für den von Guile
+bereitgestellten Makrosatz @file{guile.m4}. Wenn Sie beispielsweise Automake
+in @file{/usr/local} installiert haben, würde in @file{/usr/share} nicht
+nach @file{.m4}-Dateien geschaut. In einem solchen Fall müssen Sie folgenden
+Befehl aufrufen:
+
+@example
+export ACLOCAL_PATH=/usr/share/aclocal
+@end example
+
+In @xref{Macro Search Path,,, automake, The GNU Automake Manual} finden Sie
+weitere Informationen.
+
+Dann führen Sie wie gewohnt @command{./configure} aus. Achten Sie darauf,
+@code{--localstatedir=@var{Verzeichnis}} zu übergeben, wobei
+@var{Verzeichnis} der von Ihrer aktuellen Installation verwendete
+@code{localstatedir}-Wert ist (weitere Informationen auf @pxref{Der Store}).
+
+Zum Schluss müssen Sie @code{make check} aufrufen, um die Tests auszuführen
+(@pxref{Die Testsuite laufen lassen}). Falls etwas fehlschlägt, werfen Sie einen
+Blick auf die Installationsanweisungen (@pxref{Installation}) oder senden
+Sie eine E-Mail an die @email{guix-devel@@gnu.org, Mailingliste}.
+
+
+@node Guix vor der Installation ausführen
+@section Guix vor der Installation ausführen
+
+Um eine gesunde Arbeitsumgebung zu erhalten, ist es hilfreich, die im
+lokalen Quellbaum vorgenommenen Änderungen zunächst zu testen, ohne sie
+tatsächlich zu installieren. So können Sie zwischen Ihrem
+Endnutzer-»Straßenanzug« und Ihrem »Faschingskostüm« unterscheiden.
+
+To that end, all the command-line tools can be used even if you have not run
+@code{make install}.  To do that, you first need to have an environment with
+all the dependencies available (@pxref{Erstellung aus dem Git}), and then simply
+prefix each command with @command{./pre-inst-env} (the @file{pre-inst-env}
+script lives in the top build tree of Guix; it is generated by
+@command{./configure}), as in@footnote{The @option{-E} flag to
+@command{sudo} guarantees that @code{GUILE_LOAD_PATH} is correctly set such
+that @command{guix-daemon} and the tools it uses can find the Guile modules
+they need.}:
+
+@example
+$ sudo -E ./pre-inst-env guix-daemon --build-users-group=guixbuild
+$ ./pre-inst-env guix build hello
+@end example
+
+@noindent
+Entsprechend, um eine Guile-Sitzung zu öffnen, die die Guix-Module benutzt:
+
+@example
+$ ./pre-inst-env guile -c '(use-modules (guix utils)) (pk (%current-system))'
+
+;;; ("x86_64-linux")
+@end example
+
+@noindent
+@cindex REPL
+@cindex Lese-Auswerten-Schreiben-Schleife
+@dots{} und auf einer REPL (@pxref{Using Guile Interactively,,, guile, Guile
+Reference Manual}):
+
+@example
+$ ./pre-inst-env guile
+scheme@@(guile-user)> ,use(guix)
+scheme@@(guile-user)> ,use(gnu)
+scheme@@(guile-user)> (define snakes
+                       (fold-packages
+                         (lambda (package lst)
+                           (if (string-prefix? "python"
+                                               (package-name package))
+                               (cons package lst)
+                               lst))
+                         '()))
+scheme@@(guile-user)> (length snakes)
+$1 = 361
+@end example
+
+Das @command{pre-inst-env}-Skript richtet alle Umgebungsvariablen ein, die
+nötig sind, um dies zu ermöglichen, einschließlich @env{PATH} und
+@env{GUILE_LOAD_PATH}.
+
+Note that @command{./pre-inst-env guix pull} does @emph{not} upgrade the
+local source tree; it simply updates the @file{~/.config/guix/current}
+symlink (@pxref{Aufruf von guix pull}).  Run @command{git pull} instead if you
+want to upgrade your local source tree.
+
+
+@node Perfekt eingerichtet
+@section Perfekt eingerichtet
+
+Um perfekt für das Hacken an Guix eingerichtet zu sein, brauchen Sie an sich
+dasselbe wie um perfekt für das Hacken mit Guile (@pxref{Using Guile in
+Emacs,,, guile, Guile Reference Manual}).  Zunächst brauchen Sie mehr als
+ein Textverarbeitungsprogramm, Sie brauchen
+@url{http://www.gnu.org/software/emacs, Emacs}, ermächtigt vom wunderbaren
+@url{http://nongnu.org/geiser/, Geiser}.
+
+Geiser ermöglicht interaktive und inkrementelle Entwicklung aus Emacs
+heraus: Code kann in Puffern kompiliert und ausgewertet werden. Zugang zu
+Online-Dokumentation (Docstrings) steht ebenso zur Verfügung wie
+kontextabhängige Vervollständigung, @kbd{M-.} um zu einer Objektdefinition
+zu springen, eine REPL, um Ihren Code auszuprobieren, und mehr
+(@pxref{Einführung,,, geiser, Geiser User Manual}). Zur bequemen
+Guix-Entwicklung sollten Sie Guiles Ladepfad so ergänzen, dass die
+Quelldateien in Ihrem Checkout gefunden werden.
+
+@lisp
+;; @r{Angenommen das Guix-Checkout ist in ~/src/guix.}
+(with-eval-after-load 'geiser-guile
+  (add-to-list 'geiser-guile-load-path "~/src/guix"))
+@end lisp
+
+Um den Code tatsächlich zu bearbeiten, bietet Emacs schon einen netten
+Scheme-Modus. Aber Sie dürfen auch
+@url{http://www.emacswiki.org/emacs/ParEdit, Paredit} nicht verpassen. Es
+bietet Hilfsmittel, um direkt mit dem Syntaxbaum zu arbeiten, und kann so
+zum Beispiel einen S-Ausdruck hochheben oder ihn umhüllen, ihn verschlucken
+oder den nachfolgenden S-Ausdruck verwerfen, etc.
+
+@cindex Code-Schnipsel
+@cindex Vorlagen
+@cindex Tipparbeit sparen
+Wir bieten auch Vorlagen für häufige Git-Commit-Nachrichten und
+Paketdefinitionen im Verzeichnis @file{etc/snippets}. Diese Vorlagen können
+mit @url{http://joaotavora.github.io/yasnippet/, YASnippet} zusammen benutzt
+werden, um kurze Auslöse-Zeichenketten zu interaktiven Textschnipseln
+umzuschreiben. Vielleicht möchten Sie das Schnipselverzeichnis zu Ihrer
+@var{yas-snippet-dirs}-Variablen in Emacs hinzufügen.
+
+@lisp
+;; @r{Angenommen das Guix-Checkout ist in ~/src/guix.}
+(with-eval-after-load 'yasnippet
+  (add-to-list 'yas-snippet-dirs "~/src/guix/etc/snippets"))
+@end lisp
+
+The commit message snippets depend on @url{https://magit.vc/, Magit} to
+display staged files.  When editing a commit message type @code{add}
+followed by @kbd{TAB} to insert a commit message template for adding a
+package; type @code{update} followed by @kbd{TAB} to insert a template for
+updating a package; type @code{https} followed by @kbd{TAB} to insert a
+template for changing the home page URI of a package to HTTPS.
+
+Das Hauptschnipsel für @code{scheme-mode} wird ausgelöst, indem Sie
+@code{package...} gefolgt von @kbd{TAB} eintippen. Dieses Snippet fügt auch
+die Auslöse-Zeichenkette @code{origin...} ein, die danach weiter
+umgeschrieben werden kann. Das @code{origin}-Schnipsel kann wiederum andere
+Auslöse-Zeichenketten einfügen, die alle auf @code{...} enden, was selbst
+wieder weiter umgeschrieben werden kann.
+
+
+@node Code-Stil
+@section Code-Stil
+
+Im Allgemeinen folgt unser Code den GNU Coding Standards (@pxref{Top,,,
+standards, GNU Coding Standards}). Da diese aber nicht viel über Scheme zu
+sagen haben, folgen hier einige zusätzliche Regeln.
+
+@menu
+* Programmierparadigmen::    Wie Sie Ihre Elemente zusammenstellen.
+* Module::                   Wo Sie Ihren Code unterbringen.
+* Datentypen und Mustervergleich::  Implementierung von Datenstrukturen.
+* Formatierung von Code::    Schreibkonventionen.
+@end menu
+
+@node Programmierparadigmen
+@subsection Programmierparadigmen
+
+Scheme-Code wird in Guix auf rein funktionale Weise geschrieben. Eine
+Ausnahme ist Code, der mit Ein- und Ausgabe zu tun hat, und Prozeduren, die
+grundlegende Konzepte implementieren, wie zum Beispiel die Prozedur
+@code{memoize}.
+
+@node Module
+@subsection Module
+
+Guile-Module, die beim Erstellen nutzbar sein sollen, müssen im Namensraum
+@code{(guix build @dots{})} leben. Sie dürfen auf keine anderen Guix- oder
+GNU-Module Bezug nehmen. Jedoch ist es in Ordnung, wenn ein »wirtsseitiges«
+Modul ein erstellungsseitiges Modul benutzt.
+
+Module, die mit dem weiteren GNU-System zu tun haben, sollten im Namensraum
+@code{(gnu @dots{})} und nicht in @code{(guix @dots{})} stehen.
+
+@node Datentypen und Mustervergleich
+@subsection Datentypen und Mustervergleich
+
+Im klassischen Lisp gibt es die Tendenz, Listen zur Darstellung von allem zu
+benutzen, und diese dann »händisch« zu durchlaufen mit @code{car},
+@code{cdr}, @code{cadr} und so weiter. Dieser Stil ist aus verschiedenen
+Gründen problematisch, insbesondere wegen der Tatsache, dass er schwer zu
+lesen, schnell fehlerbehaftet und ein Hindernis beim Melden von Typfehlern
+ist.
+
+Guix-Code sollte angemessene Datentypen definieren (zum Beispiel mit
+@code{define-record-type*}) statt Listen zu missbrauchen. Außerdem sollte er
+das @code{(ice-9 match)}-Modul von Guile zum Mustervergleich benutzen,
+besonders mit Listen.

+@cindex Code-Stil
+Beim Schreiben von Scheme-Code halten wir uns an die üblichen
+Gepflogenheiten unter Scheme-Programmierern. Im Allgemeinen bedeutet das,
+dass wir uns an @url{http://mumble.net/~campbell/scheme/style.txt,
+Riastradh's Lisp Style Rules} halten. Es hat sich ergeben, dass dieses
+Dokument auch die Konventionen beschreibt, die im Code von Guile
+hauptsächlich verwendet werden. Es ist gut durchdacht und schön geschrieben,
+also lesen Sie es bitte.
+
+Ein paar in Guix eingeführte Sonderformen, wie zum Beispiel das
+@code{substitute*}-Makro, haben abweichende Regeln für die Einrückung. Diese
+sind in der Datei @file{.dir-locals.el} definiert, die Emacs automatisch
+benutzt. Beachten Sie auch, dass Emacs-Guix einen Modus namens
+@code{guix-devel-mode} bereitstellt, der Guix-Code richtig einrückt und
+hervorhebt (@pxref{Development,,, emacs-guix, The Emacs-Guix Reference
+Manual}).
+
+@cindex Einrückung, Code-
+@cindex Formatierung, Code-
+Falls Sie nicht Emacs verwenden, sollten Sie sicherstellen, dass Ihr Editor
+diese Regeln kennt. Um eine Paketdefinition automatisch einzurücken, können
+Sie auch Folgendes ausführen:
+
+@example
+./etc/indent-code.el gnu/packages/@var{Datei}.scm @var{Paket}
+@end example
+
+@noindent
+Dadurch wird die Definition von @var{Paket} in
+@file{gnu/packages/@var{Datei}.scm} automatisch eingerückt, indem Emacs im
+Batch-Modus läuft. Um die Einrückung in einer gesamten Datei vorzunehmen,
+lassen Sie das zweite Argument weg:
+
+@example
+./etc/indent-code.el gnu/services/@var{Datei}.scm
+@end example
+
+@cindex Vim, zum Editieren von Scheme-Code
+Wenn Sie Code mit Vim bearbeiten, empfehlen wir, dass Sie @code{:set
+autoindent} ausführen, damit Ihr Code automatisch eingerückt wird, während
+Sie ihn schreiben. Außerdem könnte Ihnen
+@uref{https://www.vim.org/scripts/script.php?script_id=3998,
+@code{paredit.vim}} dabei helfen, mit all diesen Klammern fertigzuwerden.
+
+Wir fordern von allen Prozeduren auf oberster Ebene, dass sie über einen
+Docstring verfügen. Diese Voraussetzung kann jedoch bei einfachen, privaten
+Prozeduren im Namensraum @code{(guix build @dots{})} aufgeweicht werden.
+
+Prozeduren sollten nicht mehr als vier positionsbestimmte Parameter
+haben. Benutzen Sie Schlüsselwort-Parameter für Prozeduren, die mehr als
+vier Parameter entgegennehmen.

+
+@node Einreichen von Patches
+@section Einreichen von Patches
+
+Die Entwicklung wird mit Hilfe des verteilten Versionskontrollsystems Git
+durchgeführt. Daher ist eine ständige Verbindung zum Repository nicht
+unbedingt erforderlich. Wir begrüßen Beiträge in Form von Patches, die
+mittels @code{git format-patch} erstellt und an die Mailingliste
+@email{guix-patches@@gnu.org} geschickt werden.
+
+Diese Mailing-Liste setzt auf einer Debbugs-Instanz auf, die zugänglich ist
+unter @uref{https://bugs.gnu.org/guix-patches}, wodurch wir den Überblick
+über Eingereichtes behalten können. Jede an diese Mailing-Liste gesendete
+Nachricht bekommt eine neue Folgenummer zugewiesen, so dass man eine
+Folge-Email zur Einreichung an @code{@var{NNN}@@debbugs.gnu.org} senden
+kann, wobei @var{NNN} für die Folgenummer steht (@pxref{Senden einer Patch-Reihe}).
+
+Bitte schreiben Sie Commit-Logs im ChangeLog-Format (@pxref{Change Logs,,,
+standards, GNU Coding Standards}); dazu finden Sie Beispiele unter den
+bisherigen Commits.
+
+Bevor Sie einen Patch einreichen, der eine Paketdefinition hinzufügt oder
+verändert, gehen Sie bitte diese Prüfliste durch:
+
+@enumerate
+@item
+Wenn die Autoren der verpackten Software eine kryptographische Signatur für
+den Tarball der Veröffentlichung anbieten, so machen Sie sich bitte die
+Mühe, die Echtheit des Archivs zu überprüfen.  Für eine abgetrennte
+GPG-Signaturdatei würden Sie das mit dem Befehl @code{gpg --verify} tun.
+
+@item
+Nehmen Sie sich die Zeit, eine passende Zusammenfassung und Beschreibung für
+das Paket zu verfassen. Unter @xref{Zusammenfassungen und Beschreibungen} finden Sie
+dazu einige Richtlinien.
+
+@item
+Verwenden Sie @code{guix lint @var{Paket}}, wobei @var{Paket} das neue oder
+geänderte Paket bezeichnet, und beheben Sie alle gemeldeten Fehler
+(@pxref{Aufruf von guix lint}).
+
+@item
+Stellen Sie sicher, dass das Paket auf Ihrer Plattform erstellt werden kann,
+indem Sie @code{guix build @var{Paket}} ausführen.
+
+@item
+@cindex gebündelt
+Achten Sie darauf, dass im Paket keine Software gebündelt mitgeliefert wird,
+die bereits in separaten Paketen zur Verfügung steht.
+
+Manchmal enthalten Pakete Kopien des Quellcodes ihrer Abhängigkeiten, um
+Nutzern die Installation zu erleichtern. Als eine Distribution wollen wir
+jedoch sicherstellen, dass solche Pakete die schon in der Distribution
+verfügbare Fassung benutzen, sofern es eine gibt. Dadurch wird sowohl der
+Ressourcenverbrauch optimiert (die Abhängigkeit wird so nur einmal erstellt
+und gespeichert) als auch der Distribution die Möglichkeit gegeben,
+ergänzende Änderungen durchzuführen, um beispielsweise
+Sicherheitsaktualisierungen für ein bestimmtes Paket an nur einem Ort
+einzuspielen, die aber das gesamte System betreffen — gebündelt
+mitgelieferte Kopien würden dies verhindern.
+
+@item
+Schauen Sie sich das von @command{guix size} ausgegebene Profil an
+(@pxref{Aufruf von guix size}). Dadurch können Sie Referenzen auf andere
+Pakete finden, die ungewollt vorhanden sind. Dies kann auch dabei helfen, zu
+entscheiden, ob das Paket aufgespalten werden sollte (@pxref{Pakete mit mehreren Ausgaben.}) und welche optionalen Abhängigkeiten verwendet werden
+sollten.
+
+@item
+Achten Sie bei wichtigen Änderungen darauf, dass abhängige Pakete (falls
+vorhanden) nicht von der Änderung beeinträchtigt werden; @code{guix refresh
+--list-dependent @var{Paket}} hilft Ihnen dabei (@pxref{Aufruf von guix refresh}).

+@cindex Branching-Strategie
+@cindex Neuerstellungs-Zeitplan
+Je nachdem, wieviele abhängige Pakete es gibt, und entsprechend wieviele
+Neuerstellungen dadurch nötig würden, finden Commits auf anderen Branches
+statt, nach ungefähr diesen Regeln:
+
+@table @asis
+@item 300 abhängige Pakete oder weniger
+@code{master}-Branch (störfreie Änderungen).
+
+@item zwischen 300 und 1200 abhängige Pakete
+@code{staging}-Branch (störfreie Änderungen). Dieser Branch wird circa alle
+3 Wochen in @code{master} gemerget. Themenbezogene Änderungen (z.B. eine
+Aktualisierung der GNOME-Plattform) können stattdessen auch auf einem
+eigenen Branch umgesetzt werden (wie @code{gnome-updates}).
+
+@item mehr als 1200 abhängige Pakete
+@code{core-updates}-Branch (kann auch größere und womöglich andere Software
+beeinträchtigende Änderungen umfassen). Dieser Branch wird planmäßig in
+@code{master} alle 2,5 Monate oder so gemerget.
+@end table
+
+All these branches are @uref{https://hydra.gnu.org/project/gnu, tracked by
+our build farm} and merged into @code{master} once everything has been
+successfully built.  This allows us to fix issues before they hit users, and
+to reduce the window during which pre-built binaries are not available.
+
+@c TODO: It would be good with badges on the website that tracks these
+@c branches.  Or maybe even a status page.
+Generally, branches other than @code{master} are considered @emph{frozen} if
+there has been a recent evaluation, or there is a corresponding @code{-next}
+branch.  Please ask on the mailing list or IRC if unsure where to place a
+patch.
+
+@item
+@cindex Determinismus, von Erstellungsprozessen
+@cindex Reproduzierbare Erstellungen, Überprüfung
+Überprüfen Sie, ob der Erstellungsprozess deterministisch ist. Dazu prüfen
+Sie typischerweise, ob eine unabhängige Erstellung des Pakets genau dasselbe
+Ergebnis wie Ihre Erstellung hat, Bit für Bit.
+
+Dies können Sie leicht tun, indem Sie dasselbe Paket mehrere Male
+hintereinander auf Ihrer Maschine erstellen (@pxref{Aufruf von guix build}):
+
+@example
+guix build --rounds=2 mein-paket
+@end example
+
+Dies reicht aus, um eine ganze Klasse häufiger Ursachen von
+Nichtdeterminismus zu finden, wie zum Beispiel Zeitstempel oder
+zufallsgenerierte Ausgaben im Ergebnis der Erstellung.
+
+Eine weitere Möglichkeit ist, @command{guix challenge} (@pxref{Aufruf von guix challenge}) zu benutzen. Sie können es ausführen, sobald ein Paket commitet
+und von @code{hydra.gnu.org} erstellt wurde, um zu sehen, ob dort dasselbe
+Ergebnis wie bei Ihnen geliefert wurde. Noch besser: Finden Sie eine andere
+Maschine, die das Paket erstellen kann, und führen Sie @command{guix
+publish} aus. Da sich die entfernte Erstellungsmaschine wahrscheinlich von
+Ihrer unterscheidet, können Sie auf diese Weise Probleme durch
+Nichtdeterminismus erkennen, die mit der Hardware zu tun haben — zum
+Beispiel die Nutzung anderer Befehlssatzerweiterungen — oder mit dem
+Betriebssystem-Kernel — zum Beispiel, indem @code{uname} oder
+@file{/proc}-Dateien verwendet werden.
+
+@item
+Beim Schreiben von Dokumentation achten Sie bitte auf eine
+geschlechtsneutrale Wortwahl, wenn Sie sich auf Personen beziehen, wie
+@uref{https://en.wikipedia.org/wiki/Singular_they, »they«@comma{}
+»their«@comma{} »them« im Singular}, und so weiter.
+
+@item
+Stelllen Sie sicher, dass Ihr Patch nur einen Satz zusammengehöriger
+Änderungen umfasst. Das Zusammenfassen nicht zusammengehöriger Änderungen
+erschwert und bremst das Durchsehen Ihres Patches.
+
+Beispiele für nicht zusammengehörige Änderungen sind das Hinzufügen mehrerer
+Pakete auf einmal, oder das Aktualisieren eines Pakets auf eine neue Version
+zusammen mit Fehlerbehebungen für das Paket.
+
+@item
+Bitte befolgen Sie unsere Richtlinien für die Code-Formatierung, womöglich
+wollen Sie dies automatisch tun lassen durch das Skript
+@command{etc/indent-code.el} (@pxref{Formatierung von Code}).
+
+@item
+When possible, use mirrors in the source URL (@pxref{Aufruf von guix download}).  Use reliable URLs, not generated ones.  For instance, GitHub
+archives are not necessarily identical from one generation to the next, so
+in this case it's often better to clone the repository.  Don't use the
+@command{name} field in the URL: it is not very useful and if the name
+changes, the URL will probably be wrong.
+
+@end enumerate
+
+Bitte benutzen Sie @samp{[PATCH] @dots{}} als Betreff, wenn Sie einen Patch
+an die Mailing-Liste schicken. Sie können dazu Ihr E-Mail-Programm oder den
+Befehl @command{git send-email} benutzen (@pxref{Senden einer Patch-Reihe}). Wir bevorzugen es, Patches als reine Textnachrichten zu erhalten,
+entweder eingebettet (inline) oder als MIME-Anhänge. Sie sind dazu
+angehalten, zu überprüfen, ob Ihr Mail-Programm solche Dinge wie
+Zeilenumbrüche oder die Einrückung verändert, wodurch die Patches womöglich
+nicht mehr funktionieren.
+
+Wenn dadurch ein Fehler behoben wurde, schließen Sie bitte den Thread, indem
+Sie eine E-Mail an @email{@var{NNN}-done@@debbugs.gnu.org} senden.

+@node Einführung
+@chapter Einführung
+
+@cindex Zweck
+GNU Guix@footnote{»Guix« wird wie »geeks« ausgesprochen, also als »ɡiːks« in
+der Notation des Internationalen Phonetischen Alphabets (IPA).} ist ein
+Werkzeug zur Paketverwaltung für das GNU-System. Guix macht es
+unprivilegierten Nutzern leicht, Pakete zu installieren, zu aktualisieren
+oder zu entfernen, zu einem vorherigen Satz von Paketen zurückzuwechseln,
+Pakete aus ihrem Quellcode heraus zu erstellen und hilft allgemein bei der
+Schöpfung und Wartung von Software-Umgebungen.
+
+@cindex Benutzeroberflächen
+Guix bietet eine befehlszeilenbasierte Paketverwaltungsschnittstelle
+(@pxref{Aufruf von guix package}), einen Satz Befehlszeilenwerkzeuge
+(@pxref{Zubehör}) sowie Schnittstellen zur Programmierung in Scheme
+(@pxref{Programmierschnittstelle}).
+@cindex Erstellungs-Daemon
+Der @dfn{Erstellungs-Daemon} ist für das Erstellen von Paketen im Auftrag
+von Nutzern verantwortlich (@pxref{Den Daemon einrichten}) und für das
+Herunterladen vorerstellter Binärdateien aus autorisierten Quellen
+(@pxref{Substitute}).
+
+@cindex Erweiterbarkeit der Distribution
+@cindex Anpassung, von Paketen
+Guix enthält Paketdefinitionen für viele Pakete, von GNU und nicht von GNU,
+die alle @uref{https://www.gnu.org/philosophy/free-sw.html, die Freiheit des
+Computernutzers respektieren}. Es ist @emph{erweiterbar}: Nutzer können ihre
+eigenen Paketdefinitionen schreiben (@pxref{Pakete definieren}) und sie als
+unabhängige Paketmodule verfügbar machen (@pxref{Paketmodule}). Es ist
+auch @emph{anpassbar}: Nutzer können spezialisierte Paketdefinitionen aus
+bestehenden @emph{ableiten}, auch von der Befehlszeile (@pxref{Paketumwandlungsoptionen}).
+
+@cindex Guix System Distribution
+@cindex GuixSD
+Sie können GNU@tie{}Guix auf ein bestehendes GNU/Linux-System aufsetzen, wo
+es die bereits verfügbaren Werkzeuge ergänzt, ohne zu stören
+(@pxref{Installation}), oder Sie können es eigenständig als Teil der
+@dfn{Guix System Distribution}, kurz GuixSD (@pxref{GNU-Distribution}),
+verwenden. Mit GNU@tie{}GuixSD @emph{deklarieren} Sie alle Aspekte der
+Betriebssystemkonfiguration und Guix kümmert sich darum, die Konfiguration
+auf transaktionsbasierte, reproduzierbare und zustandslose Weise zu
+instanzieren (@pxref{Systemkonfiguration}).
+
+@cindex funktionale Paketverwaltung
+@cindex isolation
+Intern implementiert Guix die Disziplin der @dfn{funktionalen
+Paketverwaltung}, zu der Nix schon die Pionierarbeit geleistet hat
+(@pxref{Danksagungen}). In Guix wird der Prozess, ein Paket zu erstellen
+und zu installieren, als eine @emph{Funktion} im mathematischen Sinn
+aufgefasst. Diese Funktion hat Eingaben, wie zum Beispiel
+Erstellungs-Skripts, einen Compiler und Bibliotheken, und liefert ein
+installiertes Paket. Als eine reine Funktion hängt sein Ergebnis allein von
+seinen Eingaben ab — zum Beispiel kann er nicht auf Software oder Skripts
+Bezug nehmen, die nicht ausdrücklich als Eingaben übergeben wurden. Eine
+Erstellungsfunktion führt immer zum selben Ergebnis, wenn ihr die gleiche
+Menge an Eingaben übergeben wurde. Sie kann die Umgebung des laufenden
+Systems auf keine Weise beeinflussen, zum Beispiel kann sie keine Dateien
+außerhalb ihrer Erstellungs- und Installationsverzeichnisse verändern. Um
+dies zu erreichen, laufen Erstellungsprozesse in isolieren Umgebungen
+(sogenannte @dfn{Container}), wo nur ausdrückliche Eingaben sichtbar sind.
+
+@cindex Store
+Das Ergebnis von Paketerstellungsfunktionen wird im Dateisystem
+@dfn{zwischengespeichert} in einem besonderen Verzeichnis, was als @dfn{der
+Store} bezeichnet wird (@pxref{Der Store}). Jedes Paket wird in sein eigenes
+Verzeichnis im Store installiert — standardmäßig ist er unter
+@file{/gnu/store} zu finden. Der Verzeichnisname enthält einen Hash aller
+Eingaben, anhand derer das Paket erzeugt wurde, somit hat das Ändern einer
+Eingabe einen völlig anderen Verzeichnisnamen zur Folge.
+
+Dieses Vorgehen ist die Grundlage für die Guix auszeichnenden
+Funktionalitäten: Unterstützung transaktionsbasierter Paketaktualisierungen
+und -rückstufungen, Installation von Paketen als einfacher Nutzer sowie
+Garbage Collection für Pakete (@pxref{Funktionalitäten}).

+
+@cindex Guix installieren
+@cindex official website
+GNU Guix kann von seiner Webseite unter
+@url{http://www.gnu.org/software/guix/} heruntergeladen werden. Dieser
+Abschnitt beschreibt die Software-Voraussetzungen von Guix und wie man es
+installiert, so dass man es benutzen kann.
+
+Beachten Sie, dass es in diesem Abschnitt um die Installation des
+Paketverwaltungswerkzeugs geht, welche auf einem laufenden GNU/Linux-System
+vollzogen werden kann. Falls Sie stattdessen das vollständige
+GNU-Betriebssystem installieren möchten, werfen Sie einen Blick in den
+Abschnitt @pxref{Systeminstallation}.
+
+@cindex Fremddistribution
+@cindex directories related to foreign distro
+
+Wenn es auf ein bestehendes GNU/Linux-System installiert wird — im Folgenden
+als @dfn{Fremddistribution} bezeichnet —, ergänzt GNU@tie{}Guix die
+verfügbaren Werkzeuge, ohne dass sie sich gegenseitig stören. Guix’ Daten
+befinden sich ausschließlich in zwei Verzeichnissen, üblicherweise
+@file{/gnu/store} und @file{/var/guix}; andere Dateien auf Ihrem System wie
+@file{/etc} bleiben unberührt.
+
+Sobald es installiert ist, kann Guix durch Ausführen von @command{guix pull}
+aktualisiert werden (@pxref{Aufruf von guix pull}).

+@cindex Guix aus Binärdateien installieren
+@cindex installer script
+Dieser Abschnitt beschreibt, wie sich Guix auf einem beliebigen System aus
+einem alle Komponenten umfassenden Tarball installieren lässt, der
+Binärdateien für Guix und all seine Abhängigkeiten liefert. Dies geht in der
+Regel schneller, als Guix aus seinen Quelldateien zu installieren, was in
+den nächsten Abschnitten beschrieben wird. Vorausgesetzt wird hier
+lediglich, dass GNU@tie{}tar und Xz verfügbar sind.
+
+Wir bieten ein
+@uref{https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh,
+Installations-Skript für die Shell}, welches Guix automatisch herunterlädt,
+installiert und eine erste Konfiguration von Guix mit sich bringt. Es sollte
+als der Administratornutzer (als »root«) ausgeführt werden.
+
+Die Installation läuft so ab:
+
+@enumerate
+@item
+@cindex Guix-Binärdatei herunterladen
+Download the binary tarball from
+@indicateurl{https://alpha.gnu.org/gnu/guix/guix-binary-@value{VERSION}.@var{system}.tar.xz},
+where @var{system} is @code{x86_64-linux} for an @code{x86_64} machine
+already running the kernel Linux, and so on.
+
+@c The following is somewhat duplicated in ``System Installation''.
+Achten Sie darauf, auch die zugehörige @file{.sig}-Datei herunterzuladen und
+verifizieren Sie damit die Authentizität des Tarballs, ungefähr so:
+
+@example
+$ wget https://alpha.gnu.org/gnu/guix/guix-binary-@value{VERSION}.@var{system}.tar.xz.sig
+$ gpg --verify guix-binary-@value{VERSION}.@var{system}.tar.xz.sig
+@end example
+
+Falls dieser Befehl fehlschlägt, weil Sie nicht über den nötigen
+öffentlichen Schlüssel verfügen, können Sie ihn mit diesem Befehl
+importieren:
+
+@example
+$ gpg --keyserver @value{KEY-SERVER} \
+      --recv-keys @value{OPENPGP-SIGNING-KEY-ID}
+@end example
+
+@noindent
+@c end authentication part
+und den Befehl @code{gpg --verify} erneut ausführen.
+
+@item
+Nun müssen Sie zum Administratornutzer @code{root} wechseln. Abhängig von
+Ihrer Distribution müssen Sie dazu etwa @code{su -} oder @code{sudo -i}
+ausführen. Danach führen Sie als @code{root}-Nutzer aus:
+
+@example
+# cd /tmp
+# tar --warning=no-timestamp -xf \
+     guix-binary-@value{VERSION}.@var{system}.tar.xz
+# mv var/guix /var/ && mv gnu /
+@end example
+
+Dadurch wird @file{/gnu/store} (@pxref{Der Store}) und @file{/var/guix}
+erzeugt. Letzteres enthält ein fertiges Guix-Profil für den
+Administratornutzer @code{root} (wie im nächsten Schritt beschrieben).
+
+Entpacken Sie den Tarball @emph{nicht} auf einem schon funktionierenden
+Guix-System, denn es würde seine eigenen essenziellen Dateien überschreiben.
+
+Die Befehlszeilenoption @code{--warning=no-timestamp} stellt sicher, dass
+GNU@tie{}tar nicht vor »unplausibel alten Zeitstempeln« warnt (solche
+Warnungen traten bei GNU@tie{}tar 1.26 und älter auf, neue Versionen machen
+keine Probleme). Sie treten auf, weil alle Dateien im Archiv als
+Änderungszeitpunkt null eingetragen bekommen haben (das bezeichnet den
+1. Januar 1970). Das ist Absicht, damit der Inhalt des Archivs nicht davon
+abhängt, wann es erstellt wurde, und es somit reproduzierbar wird.
+
+@item
+Make the profile available under @file{~root/.config/guix/current}, which is
+where @command{guix pull} will install updates (@pxref{Aufruf von guix pull}):
+
+@example
+# mkdir -p ~root/.config/guix
+# ln -sf /var/guix/profiles/per-user/root/current-guix \
+         ~root/.config/guix/current
+@end example
+
+»Sourcen« Sie @file{etc/profile}, um @code{PATH} und andere relevante
+Umgebungsvariable zu ergänzen:
+
+@example
+# GUIX_PROFILE="`echo ~root`/.config/guix/current" ; \
+  source $GUIX_PROFILE/etc/profile
+@end example
+
+@item
+Erzeugen Sie Nutzergruppe und Nutzerkonten für die Erstellungs-Benutzer wie
+folgt (@pxref{Einrichten der Erstellungsumgebung}).
+
+@item
+Führen Sie den Daemon aus, und lassen Sie ihn automatisch bei jedem
+Hochfahren starten.
+
+Wenn Ihre Wirts-Distribution systemd als »init«-System verwendet, können Sie
+das mit folgenden Befehlen veranlassen:
+
+@c Versions of systemd that supported symlinked service files are not
+@c yet widely deployed, so we should suggest that users copy the service
+@c files into place.
+@c
+@c See this thread for more information:
+@c http://lists.gnu.org/archive/html/guix-devel/2017-01/msg01199.html
+
+@example
+# cp ~root/.config/guix/current/lib/systemd/system/guix-daemon.service \
+     /etc/systemd/system/
+# systemctl start guix-daemon && systemctl enable guix-daemon
+@end example
+
+Wenn Ihre Wirts-Distribution als »init«-System Upstart verwendet:
+
+@example
+# initctl reload-configuration
+# cp ~root/.config/guix/current/lib/upstart/system/guix-daemon.conf \
+     /etc/init/
+# start guix-daemon
+@end example
+
+Andernfalls können Sie den Daemon immer noch manuell starten, mit:
+
+@example
+# ~root/.config/guix/current/bin/guix-daemon \
+       --build-users-group=guixbuild
+@end example
+
+@item
+Stellen Sie den @command{guix}-Befehl auch anderen Nutzern Ihrer Maschine
+zur Verfügung, zum Beispiel so:
+
+@example
+# mkdir -p /usr/local/bin
+# cd /usr/local/bin
+# ln -s /var/guix/profiles/per-user/root/current-guix/bin/guix
+@end example
+
+Es ist auch eine gute Idee, die Info-Version dieses Handbuchs ebenso
+verfügbar zu machen:
+
+@example
+# mkdir -p /usr/local/share/info
+# cd /usr/local/share/info
+# for i in /var/guix/profiles/per-user/root/current-guix/share/info/* ;
+  do ln -s $i ; done
+@end example
+
+Auf diese Art wird, unter der Annahme, dass bei Ihnen
+@file{/usr/local/share/info} im Suchpfad eingetragen ist, das Ausführen von
+@command{info guix} dieses Handbuch öffnen (@pxref{Other Info Directories,,,
+texinfo, GNU Texinfo} hat weitere Details, wie Sie den Info-Suchpfad ändern
+können).
+
+@item
+@cindex Substitute, deren Autorisierung
+Um Substitute von @code{hydra.gnu.org} oder einem Spiegelserver davon zu
+benutzen (@pxref{Substitute}), müssen sie erst autorisiert werden:
+
+@example
+# guix archive --authorize < \
+     ~root/.config/guix/current/share/guix/hydra.gnu.org.pub
+@end example
+
+@item
+Alle Nutzer müssen womöglich ein paar zusätzliche Schritte ausführen, damit
+ihre Guix-Umgebung genutzt werden kann, siehe @pxref{Anwendungen einrichten}.
+@end enumerate
+
+Voilà, die Installation ist fertig!
+
+Sie können nachprüfen, dass Guix funktioniert, indem Sie ein Beispielpaket
+in das root-Profil installieren:
+
+@example
+# guix package -i hello
+@end example
+
+The @code{guix} package must remain available in @code{root}'s profile, or
+it would become subject to garbage collection---in which case you would find
+yourself badly handicapped by the lack of the @command{guix} command.  In
+other words, do not remove @code{guix} by running @code{guix package -r
+guix}.
+
+Der Tarball zur Installation aus einer Binärdatei kann einfach durch
+Ausführung des folgenden Befehls im Guix-Quellbaum (re-)produziert und
+verifiziert werden:
+
+@example
+make guix-binary.@var{system}.tar.xz
+@end example
+

+@node Voraussetzungen
+@section Voraussetzungen
+
+Dieser Abschnitt listet Voraussetzungen auf, um Guix aus seinem Quellcode zu
+erstellen. Der Erstellungsprozess für Guix ist derselbe wie für andere
+GNU-Software und wird hier nicht beschrieben. Bitte lesen Sie die Dateien
+@file{README} und @file{INSTALL} im Guix-Quellbaum, um weitere Details zu
+erfahren.
+
+GNU Guix hat folgende Pakete als Abhängigkeiten:
+
+@itemize
+@item @url{http://gnu.org/software/guile/, GNU Guile}, Version 2.0.13 oder
+neuer, einschließlich 2.2.x,
+@item @url{https://notabug.org/cwebber/guile-gcrypt, Guile-Gcrypt}, version
+0.1.0 or later;
+@item
+@uref{http://gnutls.org/, GnuTLS}, im Speziellen dessen Bindungen für Guile
+(@pxref{Guile Preparations, how to install the GnuTLS bindings for Guile,,
+gnutls-guile, GnuTLS-Guile}),
+@item
+@uref{https://notabug.org/guile-sqlite3/guile-sqlite3, Guile-SQLite3},
+version 0.1.0 or later;
+@item
+@c FIXME: Specify a version number once a release has been made.
+@uref{https://gitlab.com/guile-git/guile-git, Guile-Git}, vom August 2017
+oder neuer,
+@item @url{http://zlib.net, zlib},
+@item @url{http://www.gnu.org/software/make/, GNU Make}.
+@end itemize
+
+Folgende Abhängigkeiten sind optional:
+
+@itemize
+@item
+Wenn Sie @url{http://savannah.nongnu.org/projects/guile-json/, Guile-JSON}
+installieren, können Sie den Befehl @command{guix import pypi} benutzen
+(@pxref{Aufruf von guix import}). Das spielt hauptsächlich für Entwickler und
+nicht für Gelegenheitsnutzer eine Rolle.
+
+@item
+@c Note: We need at least 0.10.2 for 'channel-send-eof'.
+Unterstützung für das Auslagern von Erstellungen (@pxref{Auslagern des Daemons einrichten}) und @command{guix copy} (@pxref{Aufruf von guix copy}) hängt von
+@uref{https://github.com/artyom-poptsov/guile-ssh, Guile-SSH}, Version
+0.10.2 oder neuer, ab.
+
+@item
+Wenn @url{http://www.bzip.org, libbz2} verfügbar ist, kann
+@command{guix-daemon} damit Erstellungsprotokolle komprimieren.
+@end itemize
+
+Sofern nicht @code{--disable-daemon} beim Aufruf von @command{configure}
+übergeben wurde, benötigen Sie auch folgende Pakete:
+
+@itemize
+@item @url{http://gnupg.org/, GNU libgcrypt},
+@item @url{http://sqlite.org, SQLite 3},
+@item @url{http://gcc.gnu.org, GCC's g++} mit Unterstützung für den
+C++11-Standard.
+@end itemize
+
+@cindex Zustandsverzeichnis
+Sollten Sie Guix auf einem System konfigurieren, auf dem Guix bereits
+installiert ist, dann stellen Sie sicher, dasselbe Zustandsverzeichnis wie
+für die bestehende Installation zu verwenden. Benutzen Sie dazu die
+Befehlszeilenoption @code{--localstatedir} des @command{configure}-Skripts
+(@pxref{Directory Variables, @code{localstatedir},, standards, GNU Coding
+Standards}). Das @command{configure}-Skript schützt vor ungewollter
+Fehlkonfiguration der @var{localstatedir}, damit sie nicht versehentlich
+Ihren Store verfälschen (@pxref{Der Store}).
+
+@cindex Nix, Kompatibilität
+Wenn eine funktionierende Installation of @url{http://nixos.org/nix/, the
+Nix package manager} verfügbar ist, können Sie Guix stattdessen mit
+@code{--disable-daemon} konfigurieren. In diesem Fall ersetzt Nix die drei
+oben genannten Abhängigkeiten.
+
+Guix ist mit Nix kompatibel, daher ist es möglich, denselben Store für beide
+zu verwenden. Dazu müssen Sie an @command{configure} nicht nur denselben
+Wert für @code{--with-store-dir} übergeben, sondern auch denselben Wert für
+@code{--localstatedir}. Letzterer ist deswegen essenziell, weil er unter
+Anderem angibt, wo die Datenbank liegt, in der sich die Metainformationen
+über den Store befinden. Für Nix sind die Werte standardmäßig
+@code{--with-store-dir=/nix/store} und
+@code{--localstatedir=/nix/var}. Beachten Sie, dass @code{--disable-daemon}
+nicht erforderlich ist, wenn Sie die Absicht haben, den Store mit Nix zu
+teilen.
+
+@node Die Testsuite laufen lassen
+@section Die Testsuite laufen lassen
+
+@cindex Testkatalog
+Nachdem @command{configure} und @code{make} erfolgreich durchgelaufen sind,
+ist es ratsam, den Testkatalog auszuführen. Er kann dabei helfen, Probleme
+mit der Einrichtung oder Systemumgebung zu finden, oder auch Probleme in
+Guix selbst — und Testfehler zu melden ist eine wirklich gute Art und Weise,
+bei der Verbesserung von Guix mitzuhelfen. Um den Testkatalog auszuführen,
+geben Sie Folgendes ein:
+
+@example
+make check
+@end example
+
+Testfälle können parallel ausgeführt werden. Sie können die
+Befehlszeiltenoption @code{-j} von GNU@tie{}make benutzen, damit es
+schneller geht. Der erste Durchlauf kann auf neuen Maschinen ein paar
+Minuten dauern, nachfolgende Ausführungen werden schneller sein, weil der
+für die Tests erstellte Store schon einige Dinge zwischengespeichert haben
+wird.
+
+Es ist auch möglich, eine Teilmenge der Tests laufen zu lassen, indem Sie
+die @code{TESTS}-Variable des Makefiles ähnlich wie in diesem Beispiel
+definieren:
+
+@example
+make check TESTS="tests/store.scm tests/cpio.scm"
+@end example
+
+Standardmäßig werden Testergebnisse pro Datei angezeigt. Um die Details
+jedes einzelnen Testfalls zu sehen, können Sie wie in diesem Beispiel die
+@code{SCM_LOG_DRIVER_FLAGS}-Variable des Makefiles definieren:
+
+@example
+make check TESTS="tests/base64.scm" SCM_LOG_DRIVER_FLAGS="--brief=no"
+@end example
+
+Kommt es zum Fehlschlag, senden Sie bitte eine E-Mail an
+@email{bug-guix@@gnu.org} und fügen Sie die Datei @file{test-suite.log} als
+Anhang bei. Bitte geben Sie dabei in Ihrer Nachricht die benutzte Version
+von Guix an sowie die Versionsnummern der Abhängigkeiten
+(@pxref{Voraussetzungen}).
+
+Guix wird auch mit einem Testkatalog für das ganze System ausgeliefert, der
+vollständige Instanzen des GuixSD-Betriebssystems testet. Er kann nur auf
+Systemen benutzt werden, auf denen Guix bereits installiert ist, mit
+folgendem Befehl:
+
+@example
+make check-system
+@end example
+
+@noindent
+Oder, auch hier, indem Sie @code{TESTS} definieren, um eine Teilmenge der
+auszuführenden Tests anzugeben:
+
+@example
+make check-system TESTS="basic mcron"
+@end example
+
+Diese Systemtests sind in den @code{(gnu tests @dots{})}-Modulen
+definiert. Sie funktionieren, indem Sie das getestete Betriebssystem mitsamt
+schlichter Instrumentierung in einer virtuellen Maschine (VM) ausführen. Die
+Tests können aufwendige Berechnungen durchführen oder sie günstig umgehen,
+je nachdem, ob für ihre Abhängigkeiten Substitute zur Verfügung stehen
+(@pxref{Substitute}). Manche von ihnen nehmen viel Speicherplatz in
+Anspruch, um die VM-Abbilder zu speichern.
+
+Auch hier gilt: Falls Testfehler auftreten, senden Sie bitte alle Details an
+@email{bug-guix@@gnu.org}.
+
+@node Den Daemon einrichten
+@section Den Daemon einrichten
+
+@cindex Daemon
+Operationen wie das Erstellen eines Pakets oder Laufenlassen des
+Müllsammlers werden alle durch einen spezialisierten Prozess durchgeführt,
+den @dfn{Erstellungs-Daemon}, im Auftrag seiner Kunden (den Clients). Nur
+der Daemon darf auf den Store und seine zugehörige Datenbank
+zugreifen. Daher wird jede den Store verändernde Operation durch den Daemon
+durchgeführt. Zum Beispiel kommunizieren Befehlszeilenwerkzeuge wie
+@command{guix package} und @command{guix build} mit dem Daemon (mittels
+entfernter Prozeduraufrufe), um ihm Anweisungen zu geben, was er tun soll.
+
+Folgende Abschnitte beschreiben, wie Sie die Umgebung des
+Erstellungs-Daemons ausstatten sollten. Siehe auch @ref{Substitute} für
+Informationen darüber, wie Sie es dem Daemon ermöglichen, vorerstellte
+Binärdateien herunterzuladen.
+
+@menu

+@end menu
+
+@node Einrichten der Erstellungsumgebung
+@subsection Einrichten der Erstellungsumgebung
+
+@cindex Erstellungsumgebung
+In einem normalen Mehrbenutzersystem werden Guix und sein Daemon — das
+Programm @command{guix-daemon} — vom Systemadministrator installiert;
+@file{/gnu/store} gehört @code{root} und @command{guix-daemon} läuft als
+@code{root}. Nicht mit erweiterten Rechten ausgestattete Nutzer können
+Guix-Werkzeuge benutzen, um Pakete zu erstellen oder anderweitig auf den
+Store zuzugreifen, und der Daemon wird dies für sie erledigen und dabei
+sicherstellen, dass der Store in einem konsistenten Zustand verbleibt und
+sich die Nutzer erstellte Pakete teilen.
+
+@cindex Erstellungsbenutzer
+Wenn @command{guix-daemon} als Administratornutzer @code{root} läuft, wollen
+Sie aber vielleicht dennoch nicht, dass Paketerstellungsprozesse auch als
+@code{root} ablaufen, aus offensichtlichen Sicherheitsgründen. Um dies zu
+vermeiden, sollte ein besonderer Pool aus @dfn{Erstellungsbenutzern}
+geschaffen werden, damit vom Daemon gestartete Erstellungsprozesse ihn
+benutzen. Diese Erstellungsbenutzer müssen weder eine Shell noch einen
+Persönlichen Ordner zugewiesen bekommen, sie werden lediglich benutzt, wenn
+der Daemon @code{root}-Rechte in Erstellungsprozessen ablegt. Mehrere solche
+Benutzer zu haben, ermöglicht es dem Daemon, verschiedene
+Erstellungsprozessen unter verschiedenen Benutzeridentifikatoren (UIDs) zu
+starten, was garantiert, dass sie einander nicht stören — eine essenzielle
+Funktionalität, da Erstellungen als reine Funktionen angesehen werden
+(@pxref{Einführung}).
+
+Auf einem GNU/Linux-System kann ein Pool von Erstellungsbenutzern wie folgt
+erzeugt werden (mit Bash-Syntax und den Befehlen von @code{shadow}):
+
+@c See http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00239.html
+@c for why `-G' is needed.
+@example
+# groupadd --system guixbuild
+# for i in `seq -w 1 10`;
+  do
+    useradd -g guixbuild -G guixbuild                  \
+            -d /var/empty -s `which nologin`           \
+            -c "Guix-Erstellungsbenutzer $i" --system  \
+            guixbuilder$i;
+  done
+@end example
+
+@noindent
+Die Anzahl der Erstellungsbenutzer entscheidet, wieviele Erstellungsaufträge
+parallel ausgeführt werden können, wie es mit der Befehlszeilenoption
+@option{--max-jobs} vorgegeben werden kann (@pxref{Aufruf des guix-daemon,
+@option{--max-jobs}}). Um @command{guix system vm} und ähnliche Befehle
+nutzen zu können, müssen Sie die Erstellungsbenutzer unter Umständen zur
+@code{kvm}-Benutzergruppe hinzufügen, damit sie Zugriff auf @file{/dev/kvm}
+haben, mit @code{-G guixbuild,kvm} statt @code{-G guixbuild}
+(@pxref{Aufruf von guix system}).
+
+Das Programm @code{guix-daemon} kann mit dem folgenden Befehl als
+@code{root} gestartet werden@footnote{Wenn Ihre Maschine systemd als
+»init«-System verwendet, genügt es, die Datei
+@file{@var{prefix}/lib/systemd/system/guix-daemon.service} in
+@file{/etc/systemd/system} zu platzieren, damit @command{guix-daemon}
+automatisch gestartet wird. Ebenso können Sie, wenn Ihre Maschine Upstart
+als »init«-System benutzt, die Datei
+@file{@var{prefix}/lib/upstart/system/guix-daemon.conf} in @file{/etc/init}
+platzieren.}:
+
+@example
+# guix-daemon --build-users-group=guixbuild
+@end example
+
+@cindex chroot
+@noindent
+Auf diese Weise startet der Daemon Erstellungsprozesse in einem chroot als
+einer der @code{guixbuilder}-Benutzer. Auf GNU/Linux enthält die
+chroot-Umgebung standardmäßig nichts außer:
+
+@c Keep this list in sync with libstore/build.cc! -----------------------
+@itemize
+@item
+einem minimalen @code{/dev}-Verzeichnis, was größtenteils vom @code{/dev}
+des Wirtssystems unabhängig erstellt wurde@footnote{»Größtenteils«, denn
+obwohl die Menge an Dateien, die im @code{/dev} des chroots vorkommen, fest
+ist, können die meisten dieser Dateien nur dann erstellt werden, wenn das
+Wirtssystem sie auch hat.},
+
+@item
+dem @code{/proc}-Verzeichnis, es zeigt nur die Prozesse des Containers, weil
+ein separater Namensraum für Prozess-IDs (PIDs) benutzt wird,
+
+@item
+@file{/etc/passwd} mit einem Eintrag für den aktuellen Benutzer und einem
+Eintrag für den Benutzer @file{nobody},
+
+@item
+@file{/etc/group} mit einem Eintrag für die Gruppe des Benutzers,
+
+@item
+@file{/etc/hosts} mit einem Eintrag, der @code{localhost} auf
+@code{127.0.0.1} abbildet,
+
+@item
+einem @file{/tmp}-Verzeichnis mit Schreibrechten.
+@end itemize
+
+Sie können beeinflussen, in welchem Verzeichnis der Daemon Erstellungsbäume
+unterbringt, indem sie den Wert der Umgebungsvariablen @code{TMPDIR}
+ändern. Allerdings heißt innerhalb des chroots der Erstellungsbaum immer
+@file{/tmp/guix-build-@var{name}.drv-0}, wobei @var{name} der Ableitungsname
+ist — z.B. @code{coreutils-8.24}. Dadurch hat der Wert von @code{TMPDIR}
+keinen Einfluss auf die Erstellungsumgebung, wodurch Unterschiede vermieden
+werden, falls Erstellungsprozesse den Namen ihres Erstellungsbaumes
+einfangen.
+
+@vindex http_proxy
+Der Daemon befolgt außerdem den Wert der Umgebungsvariablen
+@code{http_proxy} für von ihm durchgeführte HTTP-Downloads, sei es für
+Ableitungen mit fester Ausgabe (@pxref{Ableitungen}) oder für Substitute
+(@pxref{Substitute}).
+
+Wenn Sie Guix als ein Benutzer ohne erweiterte Rechte installieren, ist es
+dennoch möglich, @command{guix-daemon} auszuführen, sofern Sie
+@code{--disable-chroot} übergeben. Allerdings können Erstellungsprozesse
+dann nicht voneinander und vom Rest des Systems isoliert werden. Daher
+können sich Erstellungsprozesse gegenseitig stören und auf Programme,
+Bibliotheken und andere Dateien zugreifen, die dem restlichen System zur
+Verfügung stehen — was es deutlich schwerer macht, sie als @emph{reine}
+Funktionen aufzufassen.
+
+
+@node Auslagern des Daemons einrichten
+@subsection Nutzung der Auslagerungsfunktionalität
+
+@cindex auslagern
+@cindex Build-Hook
+Wenn erwünscht kann der Erstellungs-Daemon Ableitungserstellungen
+@dfn{auslagern} auf andere Maschinen, auf denen Guix läuft, mit Hilfe des
+@code{offload}-»@dfn{Build-Hooks}«@footnote{Diese Funktionalität ist nur
+verfügbar, wenn @uref{https://github.com/artyom-poptsov/guile-ssh,
+Guile-SSH} vorhanden ist.}. Wenn diese Funktionalität aktiviert ist, wird
+eine nutzerspezifizierte Liste von Erstellungsmaschinen aus
+@file{/etc/guix/machines.scm} gelesen. Wann immer eine Erstellung angefragt
+wird, zum Beispiel durch @code{guix build}, versucht der Daemon, sie an eine
+der Erstellungsmaschinen auszulagern, die die Einschränkungen der Ableitung
+erfüllen, insbesondere ihren Systemtyp — z.B. @file{x86_64-linux}. Fehlende
+Voraussetzungen für die Erstellung werden über SSH auf die Zielmaschine
+kopiert, welche dann mit der Erstellung weitermacht. Hat sie Erfolg damit,
+so werden die Ausgabe oder Ausgaben der Erstellung zurück auf die
+ursprüngliche Maschine kopiert.
+
+Die Datei @file{/etc/guix/machines.scm} sieht normalerweise so aus:
+
+@example
+(list (build-machine
+        (name "eightysix.example.org")
+        (system "x86_64-linux")
+        (host-key "ssh-ed25519 AAAAC3Nza@dots{}")
+        (user "bob")
+        (speed 2.))     ;unglaublich schnell!
+
+      (build-machine
+        (name "meeps.example.org")
+        (system "mips64el-linux")
+        (host-key "ssh-rsa AAAAB3Nza@dots{}")
+        (user "alice")
+        (private-key
+         (string-append (getenv "HOME")
+                        "/.ssh/identität-für-guix"))))
+@end example
+
+@noindent
+Im obigen Beispiel geben wir eine Liste mit zwei Erstellungsmaschinen vor,
+eine für die @code{x86_64}-Architektur und eine für die
+@code{mips64el}-Architektur.
+
+Tatsächlich ist diese Datei — wenig überraschend! — eine Scheme-Datei, die
+ausgewertet wird, wenn der @code{offload}-Hook gestartet wird. Der Wert, den
+sie zurückliefert, muss eine Liste von @code{build-machine}-Objekten
+sein. Obwohl dieses Beispiel eine feste Liste von Erstellungsmaschinen
+zeigt, könnte man auch auf die Idee kommen, etwa mit DNS-SD eine Liste
+möglicher im lokalen Netzwerk entdeckter Erstellungsmaschinen zu liefern
+(@pxref{Einführung, Guile-Avahi,, guile-avahi, Using Avahi in Guile Scheme
+Programs}). Der Datentyp @code{build-machine} wird im Folgenden weiter
+ausgeführt.
+
+@deftp {Datentyp} build-machine
+Dieser Datentyp repräsentiert Erstellungsmaschinen, an die der Daemon
+Erstellungen auslagern darf. Die wichtigen Felder sind:
+
+@table @code
+
+@item name
+Der Hostname der entfernten Maschine.
+
+@item system
+Der Systemtyp der entfernten Maschine — z.B. @code{"x86_64-linux"}.
+
+@item user
+Das Benutzerkonto, mit dem eine Verbindung zur entfernten Maschine über SSH
+aufgebaut werden soll. Beachten Sie, dass das SSH-Schlüsselpaar @emph{nicht}
+durch eine Passphrase geschützt sein darf, damit nicht-interaktive
+Anmeldungen möglich sind.
+
+@item host-key
+Dies muss der @dfn{öffentliche SSH-Host-Schlüssel} der Maschine im
+OpenSSH-Format sein. Er wird benutzt, um die Identität der Maschine zu
+prüfen, wenn wir uns mit ihr verbinden. Er ist eine lange Zeichenkette, die
+ungefähr so aussieht:
+
+@example
+ssh-ed25519 AAAAC3NzaC@dots{}mde+UhL hint@@example.org
+@end example
+
+Wenn auf der Maschine der OpenSSH-Daemon, @command{sshd}, läuft, ist der
+Host-Schlüssel in einer Datei wie @file{/etc/ssh/ssh_host_ed25519_key.pub}
+zu finden.
+
+Wenn auf der Maschine der SSH-Daemon von GNU@tie{}lsh, nämlich
+@command{lshd}, läuft, befindet sich der Host-Schlüssel in
+@file{/etc/lsh/host-key.pub} oder einer ähnlichen Datei. Er kann ins
+OpenSSH-Format umgewandelt werden durch @command{lsh-export-key}
+(@pxref{Converting keys,,, lsh, LSH Manual}):
+
+@example
+$ lsh-export-key --openssh < /etc/lsh/host-key.pub 
+ssh-rsa AAAAB3NzaC1yc2EAAAAEOp8FoQAAAQEAs1eB46LV@dots{}
+@end example
+
+@end table
+
+Eine Reihe optionaler Felder kann festgelegt werden:
+
+@table @asis
+
+@item @code{port} (Vorgabe: @code{22})
+Portnummer des SSH-Servers auf der Maschine.
+
+@item @code{private-key} (Vorgabe: @file{~root/.ssh/id_rsa})
+The SSH private key file to use when connecting to the machine, in OpenSSH
+format.  This key must not be protected with a passphrase.
+
+Beachten Sie, dass als Vorgabewert der private Schlüssel @emph{des
+root-Benutzers} genommen wird. Vergewissern Sie sich, dass er existiert,
+wenn Sie die Standardeinstellung verwenden.
+
+@item @code{compression} (Vorgabe: @code{"zlib@@openssh.com,zlib"})
+@itemx @code{compression-level} (Vorgabe: @code{3})
+Die Kompressionsmethoden auf SSH-Ebene und das angefragte
+Kompressionsniveau.
+
+Beachten Sie, dass Auslagerungen SSH-Kompression benötigen, um beim
+Übertragen von Dateien an Erstellungsmaschinen und zurück weniger Bandbreite
+zu benutzen.
+
+@item @code{daemon-socket} (Vorgabe: @code{"/var/guix/daemon-socket/socket"})
+Dateiname des Unix-Sockets, auf dem @command{guix-daemon} auf der Maschine
+lauscht.
+
+@item @code{parallel-builds} (Vorgabe: @code{1})
+Die Anzahl der Erstellungen, die auf der Maschine parallel ausgeführt werden
+können.
+
+@item @code{speed} (Vorgabe: @code{1.0})
+Ein »relativer Geschwindigkeitsfaktor«. Der Auslagerungsplaner gibt
+tendenziell Maschinen mit höherem Geschwindigkeitsfaktor den Vorrang.
+
+@item @code{features} (Vorgabe: @code{'()})
+Eine Liste von Zeichenketten, die besondere von der Maschine unterstützte
+Funktionalitäten bezeichnen. Ein Beispiel ist @code{"kvm"} für Maschinen,
+die über die KVM-Linux-Module zusammen mit entsprechender
+Hardware-Unterstützung verfügen. Ableitungen können Funktionalitäten dem
+Namen nach anfragen und werden dann auf passenden Erstellungsmaschinen
+eingeplant.
+
+@end table
+@end deftp
+
+Der Befehl @code{guile} muss sich im Suchpfad der Erstellungsmaschinen
+befinden. Zusätzlich müssen die Guix-Module im @code{$GUILE_LOAD_PATH} auf
+den Erstellungsmaschinen zu finden sein — um dies nachzuprüfen, können Sie
+Folgendes ausführen:
+
+@example
+ssh build-machine guile -c "'(use-modules (guix config))'"
+@end example
+
+Es gibt noch eine weitere Sache zu tun, sobald @file{machines.scm}
+eingerichtet ist. Wie zuvor erklärt, werden beim Auslagern Dateien zwischen
+den Stores der Maschinen hin- und hergeschickt. Damit das funktioniert,
+müssen Sie als Erstes ein Schlüsselpaar auf jeder Maschine erzeugen, damit
+der Daemon signierte Archive mit den Dateien aus dem Store versenden kann
+(@pxref{Aufruf von guix archive}):
+
+@example
+# guix archive --generate-key
+@end example
+
+@noindent
+Jede Erstellungsmaschine muss den Schlüssel der Hauptmaschine autorisieren,
+damit diese Store-Objekte von der Hauptmaschine empfangen kann:
+
+@example
+# guix archive --authorize < öffentlicher-schlüssel-hauptmaschine.txt
+@end example
+
+@noindent
+Andersherum muss auch die Hauptmaschine den jeweiligen Schlüssel jeder
+Erstellungsmaschine autorisieren.
+
+Der ganze Umstand mit den Schlüsseln soll ausdrücken, dass sich Haupt- und
+Erstellungsmaschinen paarweise gegenseitig vertrauen. Konkret kann der
+Erstellungs-Daemon auf der Hauptmaschine die Echtheit von den
+Erstellungsmaschinen empfangener Dateien gewährleisten (und umgekehrt), und
+auch dass sie nicht sabotiert wurden und mit einem autorisierten Schlüssel
+signiert wurden.
+
+@cindex Auslagerung testen
+Um zu testen, ob Ihr System funktioniert, führen Sie diesen Befehl auf der
+Hauptmaschine aus:
+
+@example
+# guix offload test
+@end example
+
+Dadurch wird versucht, zu jeder Erstellungsmaschine eine Verbindung
+herzustellen, die in @file{/etc/guix/machines.scm} angegeben wurde,
+sichergestellt, dass auf jeder Guile und die Guix-Module nutzbar sind, und
+jeweils versucht, etwas auf die Erstellungsmaschine zu exportieren und von
+dort zu imporieren. Dabei auftretende Fehler werden gemeldet.
+
+Wenn Sie stattdessen eine andere Maschinendatei verwenden möchten, geben Sie
+diese einfach auf der Befehlszeile an:
+
+@example
+# guix offload test maschinen-qualif.scm
+@end example
+
+Letztendlich können Sie hiermit nur die Teilmenge der Maschinen testen,
+deren Name zu einem regulären Ausdruck passt:
+
+@example
+# guix offload test maschinen.scm '\.gnu\.org$'
+@end example
+
+@cindex Auslagerungs-Lagebericht
+Um die momentane Auslastung aller Erstellungs-Hosts anzuzeigen, führen Sie
+diesen Befehl auf dem Hauptknoten aus:
+
+@example
+# guix offload status
+@end example
+
+
+@node SELinux-Unterstützung
+@subsection SELinux-Unterstützung
+
+@cindex SELinux, Policy für den Daemon
+@cindex Mandatory Access Control, SELinux
+@cindex Sicherheit, des guix-daemon
+Guix enthält eine SELinux-Richtliniendatei (»Policy«) unter
+@file{etc/guix-daemon.cil}, die auf einem System installiert werden
+kann, auf dem SELinux aktiviert ist, damit Guix-Dateien gekennzeichnet
+sind, und um das erwartete Verhalten des Daemons anzugeben. Da GuixSD
+keine Grundrichtlinie (»Base Policy«) für SELinux bietet, kann diese
+Richtlinie für den Daemon auf GuixSD nicht benutzt werden.
+
+@subsubsection Installieren der SELinux-Policy
+@cindex SELinux, Policy installieren
+Um die Richtlinie (Policy) zu installieren, führen Sie folgenden Befehl mit
+Administratorrechten aus:
+
+@example
+semodule -i etc/guix-daemon.cil
+@end example
+
+Kennzeichnen Sie dann das Dateisystem neu mit @code{restorecon} oder einem
+anderen, von Ihrem System angebotenen Mechanismus.
+
+Sobald die Richtlinie installiert ist, das Dateisystem neu gekennzeichnet
+wurde und der Daemon neugestartet wurde, sollte er im Kontext
+@code{guix_daemon_t} laufen. Sie können dies mit dem folgenden Befehl
+nachprüfen:
+
+@example
+ps -Zax | grep guix-daemon
+@end example
+
+Beobachten Sie die Protokolldateien von SELinux, wenn Sie einen Befehl wie
+@code{guix build hello} ausführen, um sich zu überzeugen, dass SELinux alle
+notwendigen Operationen gestattet.
+
+@subsubsection Einschränkungen
+@cindex SELinux, Einschränkungen
+
+Diese Richtlinie ist nicht perfekt. Im Folgenden finden Sie eine Liste von
+Einschränkungen oder merkwürdigen Verhaltensweisen, die bedacht werden
+sollten, wenn man die mitgelieferte SELinux-Richtlinie für den Guix-Daemon
+einspielt.
+
+@enumerate
+@item
+@code{guix_daemon_socket_t} wird nicht wirklich benutzt. Keine der
+Socket-Operationen benutzt Kontexte, die irgendetwas mit
+@code{guix_daemon_socket_t} zu tun haben. Es schadet nicht, diese ungenutzte
+Kennzeichnung zu haben, aber es wäre besser, für die Kennzeichnung auch
+Socket-Regeln festzulegen.
+
+@item
+@code{guix gc} kann nicht auf beliebige Verknüpfungen zu Profilen
+zugreifen. Die Kennzeichnung des Ziels einer symbolischen Verknüpfung ist
+notwendigerweise unabhängig von der Dateikennzeichnung der
+Verknüpfung. Obwohl alle Profile unter $localstatedir gekennzeichnet sind,
+erben die Verknüpfungen auf diese Profile die Kennzeichnung desjenigen
+Verzeichnisses, in dem sie sich befinden. Für Verknüpfungen im Persönlichen
+Ordner des Benutzers ist das @code{user_home_t}, aber Verknüpfungen aus dem
+Persönlichen Ordner des Administratornutzers, oder @file{/tmp}, oder das
+Arbeitsverzeichnis des HTTP-Servers, etc., funktioniert das
+nicht. @code{guix gc} würde es nicht gestattet, diese Verknüpfungen
+auszulesen oder zu verfolgen.
+
+@item
+Die vom Daemon gebotene Funktionalität, auf TCP-Verbindungen zu lauschen,
+könnte nicht mehr funktionieren. Dies könnte zusätzliche Regeln brauchen,
+weil SELinux Netzwerk-Sockets anders behandelt als Dateien.
+
+@item
+Derzeit wird allen Dateien mit einem Namen, der zum regulären Ausdruck
+@code{/gnu/store/.+-(guix-.+|profile)/bin/guix-daemon} passt, die
+Kennzeichnung @code{guix_daemon_exec_t} zugewiesen, wodurch @emph{jede
+beliebige} Datei mit diesem Namen in irgendeinem Profil gestattet wäre, in
+der Domäne @code{guix_daemon_t} ausgeführt zu werden. Das ist nicht
+ideal. Ein Angreifer könnte ein Paket erstellen, dass solch eine ausführbare
+Datei enthält, und den Nutzer überzeugen, es zu installieren und
+auszuführen. Dadurch käme es in die Domäne @code{guix_daemon_t}. Ab diesem
+Punkt könnte SELinux nicht mehr verhindern, dass es auf Dateien zugreift,
+auf die Prozesse in dieser Domäne zugreifen dürfen.
+
+Wir könnten zum Zeitpunkt der Installation eine wesentlich restriktivere
+Richtlinie generieren, für die nur @emph{genau derselbe} Dateiname des
+gerade installierten @code{guix-daemon}-Programms als
+@code{guix_daemon_exec_t} gekennzeichnet würde, statt einen vieles
+umfassenden regulären Ausdruck zu benutzen. Aber dann müsste der
+Administratornutzer zum Zeitpunkt der Installation jedes Mal die Richtlinie
+installieren oder aktualisieren müssen, sobald das Guix-Paket aktualisiert
+wird, dass das tatsächlich in Benutzung befindliche
+@code{guix-daemon}-Programm enthält.

+
+@node Aufruf des guix-daemon
+@section Aufruf von @command{guix-daemon}
+
+Das Programm @command{guix-daemon} implementiert alle Funktionalitäten, um
+auf den Store zuzugreifen. Dazu gehört das Starten von Erstellungsprozessen,
+das Ausführen des Müllsammlers, das Abfragen, ob ein Erstellungsergebnis
+verfügbar ist, etc. Normalerweise wird er so als Administratornutzer
+(@code{root}) gestartet:
+
+@example
+# guix-daemon --build-users-group=guixbuild
+@end example
+
+@noindent
+Details, wie Sie ihn einrichten, finden Sie im Abschnitt @pxref{Den Daemon einrichten}.
+
+@cindex chroot
+@cindex Container, Erstellungsumgebung
+@cindex Erstellungsumgebung
+@cindex Reproduzierbare Erstellungen
+Standardmäßig führt @command{guix-daemon} Erstellungsprozesse mit
+unterschiedlichen UIDs aus, die aus der Erstellungsgruppe stammen, deren
+Name mit @code{--build-users-group} übergeben wurde. Außerdem läuft jeder
+Erstellungsprozess in einer chroot-Umgebung, die nur die Teilmenge des
+Stores enthält, von der der Erstellungsprozess abhängt, entsprechend seiner
+Ableitung (@pxref{Programmierschnittstelle, derivation}), und ein paar
+bestimmte Systemverzeichnisse, darunter standardmäßig auch @file{/dev} und
+@file{/dev/pts}. Zudem ist die Erstellungsumgebung auf GNU/Linux ein
+@dfn{Container}: Nicht nur hat er seinen eigenen Dateisystembaum, er hat
+auch einen separaten Namensraum zum Einhängen von Dateisystemen, seinen
+eigenen Namensraum für PIDs, für Netzwerke, etc. Dies hilft dabei,
+reproduzierbare Erstellungen zu garantieren (@pxref{Funktionalitäten}).
+
+When the daemon performs a build on behalf of the user, it creates a build
+directory under @file{/tmp} or under the directory specified by its
+@code{TMPDIR} environment variable.  This directory is shared with the
+container for the duration of the build, though within the container, the
+build tree is always called @file{/tmp/guix-build-@var{name}.drv-0}.
+
+Nach Abschluss der Erstellung wird das Erstellungsverzeichnis automatisch
+entfernt, außer wenn die Erstellung fehlgeschlagen ist und der Client
+@option{--keep-failed} angegeben hat (@pxref{Aufruf von guix build,
+@option{--keep-failed}}).
+
+The daemon listens for connections and spawns one sub-process for each
+session started by a client (one of the @command{guix} sub-commands.)  The
+@command{guix processes} command allows you to get an overview of the
+activity on your system by viewing each of the active sessions and clients.
+@xref{Invoking guix processes}, for more information.
+
+Die folgenden Befehlszeilenoptionen werden unterstützt:
+
+@table @code
+@item --build-users-group=@var{Gruppe}
+Verwende die Benutzerkonten aus der @var{Gruppe}, um Erstellungsprozesse
+auszuführen (@pxref{Den Daemon einrichten, build users}).
+
+@item --no-substitutes
+@cindex Substitute
+Benutze keine Substitute für Erstellungsergebnisse. Das heißt, dass alle
+Objekte lokal erstellt werden müssen, und kein Herunterladen von vorab
+erstellten Binärdateien erlaubt ist (@pxref{Substitute}).
+
+Wenn der Daemon mit @code{--no-substitutes} ausgeführt wird, können Clients
+trotzdem Substitute explizit aktivieren über den entfernten Prozeduraufruf
+@code{set-build-options} (@pxref{Der Store}).
+
+@item --substitute-urls=@var{URLs}
+@anchor{daemon-substitute-urls}
+Benutze @var{URLs} als standardmäßige, leerzeichengetrennte Liste der
+Quell-URLs für Substitute. Wenn diese Befehlszeilenoption nicht angegeben
+wird, wird @indicateurl{https://mirror.hydra.gnu.org https://hydra.gnu.org}
+verwendet (@code{mirror.hydra.gnu.org} ist ein Spiegelserver für
+@code{hydra.gnu.org}).
+
+Das hat zur Folge, dass Substitute von den @var{URLs} heruntergeladen werden
+können, solange sie mit einer Signatur versehen sind, der vertraut wird
+(@pxref{Substitute}).
+
+@cindex Build-Hook
+@item --no-build-hook
+Den »@dfn{Build-Hook}« nicht benutzen.
+
+»Build-Hook« ist der Name eines Hilfsprogramms, das der Daemon starten kann
+und an das er Erstellungsanfragen übermittelt. Durch diesen Mechanismus
+können Erstellungen an andere Maschinen ausgelagert werden (@pxref{Auslagern des Daemons einrichten}).
+
+@item --cache-failures
+Fehler bei der Erstellung zwischenspeichern. Normalerweise werden nur
+erfolgreiche Erstellungen gespeichert.
+
+Wenn diese Befehlszeilenoption benutzt wird, kann @command{guix gc
+--list-failures} benutzt werden, um die Menge an Store-Objekten abzufragen,
+die als Fehlschläge markiert sind; @command{guix gc --clear-failures}
+entfernt Store-Objekte aus der Menge zwischengespeicherter
+Fehlschläge. @xref{Aufruf von guix gc}.
+
+@item --cores=@var{n}
+@itemx -c @var{n}
+@var{n} CPU-Kerne zum Erstellen jeder Ableitung benutzen; @code{0} heißt, so
+viele wie verfügbar sind.
+
+Der Vorgabewert ist @code{0}, jeder Client kann jedoch eine abweichende
+Anzahl vorgeben, zum Beispiel mit der Befehlszeilenoption @code{--cores} von
+@command{guix build} (@pxref{Aufruf von guix build}).
+
+Dadurch wird die Umgebungsvariable @code{NIX_BUILD_CORES} im
+Erstellungsprozess definiert, welcher sie benutzen kann, um intern parallele
+Ausführungen zuzulassen — zum Beispiel durch Nutzung von @code{make
+-j$NIX_BUILD_CORES}.
+
+@item --max-jobs=@var{n}
+@itemx -M @var{n}
+Höchstenss @var{n} Erstellungsaufträge parallel bearbeiten. Der Vorgabewert
+liegt bei @code{1}. Wird er auf @code{0} gesetzt, werden keine Erstellungen
+lokal durchgeführt, stattdessen lagert der Daemon sie nur aus (@pxref{Auslagern des Daemons einrichten}) oder sie schlagen einfach fehl.
+
+@item --max-silent-time=@var{Sekunden}
+Wenn der Erstellungs- oder Substitutionsprozess länger als
+@var{Sekunden}-lang keine Ausgabe erzeugt, wird er abgebrochen und ein
+Fehler beim Erstellen gemeldet.
+
+Der Vorgabewert ist @code{0}, was bedeutet, dass es keine Zeitbeschränkung
+gibt.
+
+Clients können einen anderen Wert als den hier angegebenen verwenden lassen
+(@pxref{Gemeinsame Erstellungsoptionen, @code{--max-silent-time}}).
+
+@item --timeout=@var{Sekunden}
+Entsprechend wird hier der Erstellungs- oder Substitutionsprozess
+abgebrochen und als Fehlschlag gemeldet, wenn er mehr als
+@var{Sekunden}-lang dauert.
+
+Der Vorgabewert ist @code{0}, was bedeutet, dass es keine Zeitbeschränkung
+gibt.
+
+Clients können einen anderen Wert verwenden lassen (@pxref{Gemeinsame Erstellungsoptionen, @code{--timeout}}).
+
+@item --rounds=@var{N}
+Jede Ableitung @var{n}-mal hintereinander erstellen und einen Fehler melden,
+wenn nacheinander ausgewertete Erstellungsergebnisse nicht Bit für Bit
+identisch sind. Beachten Sie, dass Clients wie @command{guix build} einen
+anderen Wert verwenden lassen können (@pxref{Aufruf von guix build}).
+
+Wenn dies zusammen mit @option{--keep-failed} benutzt wird, bleiben die sich
+unterscheidenden Ausgaben im Store unter dem Namen
+@file{/gnu/store/@dots{}-check}. Dadurch können Unterschiede zwischen den
+beiden Ergebnissen leicht erkannt werden.
+
+@item --debug
+Informationen zur Fehlersuche ausgeben.
+
+Dies ist nützlich, um Probleme beim Starten des Daemons nachzuvollziehen;
+Clients könn aber auch ein abweichenden Wert verwenden lassen, zum Beispiel
+mit der Befehlszeilenoption @code{--verbosity} von @command{guix build}
+(@pxref{Aufruf von guix build}).
+
+@item --chroot-directory=@var{Verzeichnis}
+Füge das @var{Verzeichnis} zum chroot von Erstellungen hinzu.
+
+Dadurch kann sich das Ergebnis von Erstellungsprozessen ändern — zum
+Beispiel, wenn diese optionale Abhängigkeiten aus dem @var{Verzeichnis}
+verwenden, wenn sie verfügbar sind, und nicht, wenn es fehlt. Deshalb ist es
+nicht empfohlen, dass Sie diese Befehlszeilenoption verwenden, besser
+sollten Sie dafür sorgen, dass jede Ableitung alle von ihr benötigten
+Eingabgen deklariert.
+
+@item --disable-chroot
+Erstellungen ohne chroot durchführen.
+
+Diese Befehlszeilenoption zu benutzen, wird nicht empfohlen, denn auch
+dadurch bekämen Erstellungsprozesse Zugriff auf nicht deklarierte
+Abhängigkeiten. Sie ist allerdings unvermeidlich, wenn @command{guix-daemon}
+auf einem Benutzerkonto ohne ausreichende Berechtigungen ausgeführt wird.
+
+@item --log-compression=@var{Typ}
+Erstellungsprotokolle werden entsprechend dem @var{Typ} komprimiert, der
+entweder @code{gzip}, @code{bzip2} oder @code{none} (für keine Kompression)
+sein muss.
+
+Sofern nicht @code{--lose-logs} angegeben wurde, werden alle
+Erstellungsprotokolle in der @var{localstatedir} gespeichert. Um Platz zu
+sparen, komprimiert sie der Daemon standardmäßig automatisch mit bzip2.
+
+@item --disable-deduplication
+@cindex Deduplizieren
+Automatische Dateien-»Deduplizierung« im Store ausschalten.
+
+Standardmäßig werden zum Store hinzugefügte Objekte automatisch
+»dedupliziert«: Wenn eine neue Datei mit einer anderen im Store
+übereinstimmt, wird die neue Datei stattdessen als harte Verknüpfung auf die
+andere Datei angelegt. Dies reduziert den Speicherverbrauch auf der Platte
+merklich, jedoch steigt andererseits die Auslastung bei der Ein-/Ausgabe im
+Erstellungsprozess geringfügig. Durch diese Option wird keine solche
+Optimierung durchgeführt.
+
+@item --gc-keep-outputs[=yes|no]
+Gibt an, ob der Müllsammler (Garbage Collector, GC) die Ausgaben lebendiger
+Ableitungen behalten muss (»yes«) oder nicht (»no«).
+
+@cindex GC-Wurzeln
+@cindex Müllsammlerwurzeln
+When set to ``yes'', the GC will keep the outputs of any live derivation
+available in the store---the @code{.drv} files.  The default is ``no'',
+meaning that derivation outputs are kept only if they are reachable from a
+GC root.  @xref{Aufruf von guix gc}, for more on GC roots.
+
+@item --gc-keep-derivations[=yes|no]
+Gibt an, ob der Müllsammler (GC) Ableitungen behalten muss (»yes«), wenn sie
+lebendige Ausgaben haben, oder nicht (»no«).
+
+Für »yes«, den Vorgabewert, behält der Müllsammler Ableitungen —
+z.B. @code{.drv}-Dateien —, solange zumindest eine ihrer Ausgaben lebendig
+ist. Dadurch können Nutzer den Ursprung der Dateien in ihrem Store
+nachvollziehen. Setzt man den Wert auf »no«, wird ein bisschen weniger
+Speicher auf der Platte verbraucht.
+
+In this way, setting @code{--gc-keep-derivations} to ``yes'' causes liveness
+to flow from outputs to derivations, and setting @code{--gc-keep-outputs} to
+``yes'' causes liveness to flow from derivations to outputs.  When both are
+set to ``yes'', the effect is to keep all the build prerequisites (the
+sources, compiler, libraries, and other build-time tools) of live objects in
+the store, regardless of whether these prerequisites are reachable from a GC
+root.  This is convenient for developers since it saves rebuilds or
+downloads.
+
+@item --impersonate-linux-2.6
+Auf Linux-basierten Systemen wird hiermit vorgetäuscht, dass es sich um
+Linux 2.6 handeln würde, indem der Kernel für einen
+@code{uname}-Systemaufruf als Version der Veröffentlichung mit 2.6
+antwortet.
+
+Dies kann hilfreich sein, um Programme zu erstellen, die (normalerweise zu
+Unrecht) von der Kernel-Versionsnummer abhängen.
+
+@item --lose-logs
+Keine Protokolle der Erstellungen vorhalten. Normalerweise würden solche in
+@code{@var{localstatedir}/guix/log} gespeichert.
+
+@item --system=@var{System}
+Verwende @var{System} als aktuellen Systemtyp. Standardmäßig ist dies das
+Paar aus Befehlssatz und Kernel, welches beim Aufruf von @code{configure}
+erkannt wurde, wie zum Beispiel @code{x86_64-linux}.
+
+@item --listen=@var{Endpunkt}
+Lausche am @var{Endpunkt} auf Verbindungen. Dabei wird der @var{Endpunkt}
+als Dateiname eines Unix-Sockets verstanden, wenn er mit einem @code{/}
+(Schrägstrich) beginnt. Andernfalls wird der @var{Endpunkt} als Hostname
+oder als Hostname-Port-Paar verstanden, auf dem gelauscht wird. Hier sind
+ein paar Beispiele:
+
+@table @code
+@item --listen=/gnu/var/daemon
+Lausche auf Verbindungen am Unix-Socket @file{/gnu/var/daemon}, falls nötig
+wird er dazu erstellt.
+
+@item --listen=localhost
+@cindex Daemon, Fernzugriff
+@cindex Fernzugriff auf den Daemon
+@cindex Daemon, Einrichten auf Clustern
+@cindex Cluster, Einrichtung des Daemons
+Lausche auf TCP-Verbindungen an der Netzwerkschnittstelle, die
+@code{localhost} entspricht, auf Port 44146.
+
+@item --listen=128.0.0.42:1234
+Lausche auf TCP-Verbindungen an der Netzwerkschnittstelle, die
+@code{128.0.0.42} entspricht, auf Port 1234.
+@end table
+
+Diese Befehlszeilenoption kann mehrmals wiederholt werden. In diesem Fall
+akzeptiert @command{guix-daemon} Verbindungen auf allen angegebenen
+Endpunkten. Benutzer können bei Client-Befehlen angeben, mit welchem
+Endpunkt sie sich verbinden möchten, indem sie die Umgebungsvariable
+@code{GUIX_DAEMON_SOCKET} festlegen (@pxref{Der Store,
+@code{GUIX_DAEMON_SOCKET}}).
+
+@quotation Anmerkung
+Das Daemon-Protokoll ist @emph{weder authentifiziert noch
+verschlüsselt}. Die Benutzung von @code{--listen=@var{Host}} eignet sich für
+lokale Netzwerke, wie z.B. in Rechen-Clustern, wo sich nur solche Knoten mit
+dem Daemon verbinden, denen man vertraut. In Situationen, wo ein Fernzugriff
+auf den Daemon durchgeführt wird, empfehlen wir, über Unix-Sockets in
+Verbindung mit SSH zuzugreifen.
+@end quotation
+
+Wird @code{--listen} nicht angegeben, lauscht @command{guix-daemon} auf
+Verbindungen auf dem Unix-Socket, der sich unter
+@file{@var{localstatedir}/guix/daemon-socket/socket} befindet.

+
+@cindex Fremddistribution
+Läuft Guix aufgesetzt auf einer GNU/Linux-Distribution außer GuixSD — einer
+sogenannten @dfn{Fremddistribution} —, so sind ein paar zusätzliche Schritte
+bei der Einrichtung nötig. Hier finden Sie manche davon.
+
+@subsection Locales
+
+@anchor{locales-and-locpath}
+@cindex Locales, nicht auf GuixSD
+@vindex LOCPATH
+@vindex GUIX_LOCPATH
+Über Guix installierte Pakete benutzen nicht die Daten zu Regions- und
+Spracheinstellungen (Locales) des Wirtssystems. Stattdessen müssen Sie erst
+eines der Locale-Pakete installieren, die für Guix verfügbar sind, und dann
+den Wert Ihrer Umgebungsvariablen @code{GUIX_LOCPATH} passend festlegen:
+
+@example
+$ guix package -i glibc-locales
+$ export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale
+@end example
+
+Beachten Sie, dass das Paket @code{glibc-locales} Daten für alle von
+GNU@tie{}libc unterstützten Locales enthält und deswegen um die 110@tie{}MiB
+wiegt. Alternativ gibt es auch @code{glibc-utf8-locales}, was kleiner, aber
+auf ein paar UTF-8-Locales beschränkt ist.
+
+Die Variable @code{GUIX_LOCPATH} spielt eine ähnliche Rolle wie
+@code{LOCPATH} (@pxref{Locale Names, @code{LOCPATH},, libc, The GNU C
+Library Reference Manual}). Es gibt jedoch zwei wichtige Unterschiede:
+
+@enumerate
+@item
+@code{GUIX_LOCPATH} wird nur von der libc in Guix beachtet und nicht der von
+Fremddistributionen bereitgestellten libc. Mit @code{GUIX_LOCPATH} können
+Sie daher sicherstellen, dass die Programme der Fremddistribution keine
+inkompatiblen Locale-Daten von Guix laden.
+
+@item
+libc hängt an jeden @code{GUIX_LOCPATH}-Eintrag @code{/X.Y} an, wobei
+@code{X.Y} die Version von libc ist — z.B. @code{2.22}. Sollte Ihr
+Guix-Profil eine Mischung aus Programmen enthalten, die an verschiedene
+libc-Versionen gebunden sind, wird jede nur die Locale-Daten im richtigen
+Format zu laden versuchen.
+@end enumerate
+
+Das ist wichtig, weil das Locale-Datenformat verschiedener libc-Versionen
+inkompatibel sein könnte.
+
+@subsection Name Service Switch
+
+@cindex Name Service Switch, glibc
+@cindex NSS (Name Service Switch), glibc
+@cindex nscd (Name Service Caching Daemon)
+@cindex Name Service Caching Daemon (nscd)
+Wenn Sie Guix auf einer Fremddistribution verwenden, @emph{empfehlen wir
+stärkstens}, dass Sie den @dfn{Name Service Cache Daemon} der
+GNU-C-Bibliothek, @command{nscd}, laufen lassen, welcher auf dem Socket
+@file{/var/run/nscd/socket} lauschen sollte. Wenn Sie das nicht tun, könnten
+mit Guix installierte Anwendungen Probleme beim Auflösen von Hostnamen oder
+Benutzerkonten haben, oder sogar abstürzen. Die nächsten Absätze erklären
+warum.
+
+@cindex @file{nsswitch.conf}
+Die GNU-C-Bibliothek implementiert einen @dfn{Name Service Switch} (NSS),
+welcher einen erweiterbaren Mechanismus zur allgemeinen »Namensauflösung«
+darstellt: Hostnamensauflösung, Benutzerkonten und weiteres (@pxref{Name Service Switch,,, libc, The GNU C Library Reference Manual}).
+
+@cindex Network Information Service (NIS)
+@cindex NIS (Network Information Service)
+Für die Erweiterbarkeit unterstützt der NSS @dfn{Plugins}, welche neue
+Implementierungen zur Namensauflösung bieten: Zum Beispiel ermöglicht das
+Plugin @code{nss-mdns} die Namensauflösung für @code{.local}-Hostnamen, das
+Plugin @code{nis} gestattet die Auflösung von Benutzerkonten über den
+Network Information Service (NIS) und so weiter. Diese zusätzlichen
+»Auflösungsdienste« werden systemweit konfiguriert in
+@file{/etc/nsswitch.conf} und alle auf dem System laufenden Programme halten
+sich an diese Einstellungen (@pxref{NSS Configuration File,,, libc, The GNU
+C Reference Manual}).
+
+Wenn sie eine Namensauflösung durchführen — zum Beispiel, indem sie die
+@code{getaddrinfo}-Funktion in C aufrufen — versuchen die Anwendungen als
+Erstes, sich mit dem nscd zu verbinden; ist dies erfolgreich, führt nscd für
+sie die weiteren Namensauflösungen durch. Falls nscd nicht läuft, führen sie
+selbst die Namensauflösungen durch, indem sie die Namensauflösungsdienste in
+ihren eigenen Adressraum laden und ausführen. Diese Namensauflösungsdienste
+— die @file{libnss_*.so}-Dateien — werden mit @code{dlopen} geladen, aber
+sie kommen von der C-Bibliothek des Wirtssystems und nicht von der
+C-Bibliothek, mit der die Anwendung gebunden wurde (also der C-Bibliothek
+von Guix).
+
+Und hier kommt es zum Problem: Wenn die Anwendung mit der C-Bibliothek von
+Guix (etwa glibc 2.24) gebunden wurde und die NSS-Plugins von einer anderen
+C-Bibliothek (etwa @code{libnss_mdns.so} für glibc 2.22) zu laden versucht,
+wird sie vermutlich abstürzen oder die Namensauflösungen werden unerwartet
+fehlschlagen.
+
+Durch das Ausführen von @command{nscd} auf dem System wird, neben anderen
+Vorteilen, dieses Problem der binären Inkompatibilität vermieden, weil diese
+@code{libnss_*.so}-Dateien vom @command{nscd}-Prozess geladen werden, nicht
+in den Anwendungen selbst.
+
+@subsection X11-Schriftarten
+
+@cindex Schriftarten
+Die Mehrheit der graphischen Anwendungen benutzen Fontconfig zum Finden und
+Laden von Schriftarten und für die Darstellung im X11-Client. Im Paket
+@code{fontconfig} in Guix werden Schriftarten standardmäßig in
+@file{$HOME/.guix-profile} gesucht. Um es graphischen Anwendungen, die mit
+Guix installiert wurden, zu ermöglichen, Schriftarten anzuzeigen, müssen Sie
+die Schriftarten auch mit Guix installieren. Essenzielle Pakete für
+Schriftarten sind unter Anderem @code{gs-fonts}, @code{font-dejavu} und
+@code{font-gnu-freefont-ttf}.
+
+Um auf Chinesisch, Japanisch oder Koreanisch verfassten Text in graphischen
+Anwendungen anzeigen zu können, möchten Sie vielleicht
+@code{font-adobe-source-han-sans} oder @code{font-wqy-zenhei}
+installieren. Ersteres hat mehrere Ausgaben, für jede Sprachfamilie eine
+(@pxref{Pakete mit mehreren Ausgaben.}). Zum Beispiel installiert folgender
+Befehl Schriftarten für chinesische Sprachen:
+
+@example
+guix package -i font-adobe-source-han-sans:cn
+@end example
+
+@cindex @code{xterm}
+Ältere Programme wie @command{xterm} benutzen kein Fontconfig, sondern
+X-Server-seitige Schriftartendarstellung. Solche Programme setzen voraus,
+dass der volle Name einer Schriftart mit XLFD (X Logical Font Description)
+angegeben wird, z.B. so:
+
+@example
+-*-dejavu sans-medium-r-normal-*-*-100-*-*-*-*-*-1
+@end example
+
+Um solche vollen Namen für die in Ihrem Guix-Profil installierten
+TrueType-Schriftarten zu verwenden, müssen Sie den Pfad für Schriftarten
+(Font Path) des X-Servers anpassen:
+
+@c Note: 'xset' does not accept symlinks so the trick below arranges to
+@c get at the real directory.  See <https://bugs.gnu.org/30655>.
+@example
+xset +fp $(dirname $(readlink -f ~/.guix-profile/share/fonts/truetype/fonts.dir))
+@end example
+
+@cindex @code{xlsfonts}
+Danach können Sie den Befehl @code{xlsfonts} ausführen (aus dem Paket
+@code{xlsfonts}), um sicherzustellen, dass dort Ihre TrueType-Schriftarten
+aufgeführt sind.
+
+@cindex @code{fc-cache}
+@cindex Font-Cache
+Nach der Installation der Schriftarten müssen Sie unter Umständen den
+Schriftarten-Zwischenspeicher (Font-Cache) erneuern, um diese in Anwendungen
+benutzen zu können. Gleiches gilt, wenn mit Guix installierte Anwendungen
+anscheinend keine Schriftarten finden können. Um das Erneuern des
+Font-Caches zu erzwingen, führen Sie @code{fc-cache -f} aus. Der Befehl
+@code{fc-cache} wird vom Paket @code{fontconfig} angeboten.
+
+@subsection X.509-Zertifikate
+
+@cindex @code{nss-certs}
+Das Paket @code{nss-certs} bietet X.509-Zertifikate, womit Programme die
+Identität von Web-Servern authentifizieren können, auf die über HTTPS
+zugegriffen wird.
+
+Wenn Sie Guix auf einer Fremddistribution verwenden, können Sie dieses Paket
+installieren und die relevanten Umgebungsvariablen festlegen, damit Pakete
+wissen, wo sie Zertifikate finden. In @xref{X.509-Zertifikate} stehen
+genaue Informationen.
+
+@subsection Emacs-Pakete
+
+@cindex @code{emacs}
+Wenn Sie mit Guix Pakete für Emacs installieren, werden deren elisp-Dateien
+entweder in @file{$HOME/.guix-profile/share/emacs/site-lisp/} oder in
+Unterverzeichnissen von
+@file{$HOME/.guix-profile/share/emacs/site-lisp/guix.d/}
+gespeichert. Letzteres Verzeichnis gibt es, weil es Tausende von
+Emacs-Paketen gibt und sie alle im selben Verzeichnis zu speichern
+vielleicht nicht verlässlich funktioniert (wegen Namenskonflikten). Daher
+halten wir es für richtig, für jedes Paket ein anderes Verzeichnis zu
+benutzen. Das Emacs-Paketsystem organisiert die Dateistruktur ähnlich
+(@pxref{Package Files,,, emacs, The GNU Emacs Manual}).
+
+Standardmäßig »weiß« Emacs (wenn er mit Guix installiert wurde), wo diese
+Pakete liegen, Sie müssen also nichts selbst konfigurieren. Wenn Sie aber
+aus irgendeinem Grund mit Guix installierte Pakete nicht automatisch laden
+lassen möchten, können Sie Emacs mit der Befehlszeilenoption
+@code{--no-site-file} starten (@pxref{Init File,,, emacs, The GNU Emacs
+Manual}).
+
+@subsection GCC-Toolchain
+
+@cindex GCC
+@cindex ld-wrapper
+
+Guix bietet individuelle Compiler-Pakete wie etwa @code{gcc}, aber wenn Sie
+einen vollständigen Satz an Werkzeugen zum Kompilieren und Binden von
+Quellcode brauchen, werden Sie eigentlich das Paket @code{gcc-toolchain}
+haben wollen. Das Paket bietet eine vollständige GCC-Toolchain für die
+Entwicklung mit C/C++, einschließlich GCC selbst, der GNU-C-Bibliothek
+(Header-Dateien und Binärdateien samt Symbolen zur Fehlersuche/Debugging in
+der @code{debug}-Ausgabe), Binutils und einen Wrapper für den Binder/Linker.
+
+@cindex Versuch, unreine Bibliothek zu benutzen, Fehlermeldung
+
+Der Zweck des Wrappers ist, die an den Binder übergebenen
+Befehlszeilenoptionen mit @code{-L} und @code{-l} zu überprüfen und jeweils
+passende Argumente mit @code{-rpath} anzufügen, womit dann der echte Binder
+aufgerufen wird. Standardmäßig weigert sich der Binder-Wrapper, mit
+Bibliotheken außerhalb des Stores zu binden, um »Reinheit« zu
+gewährleisten. Das kann aber stören, wenn man die Toolchain benutzt, um mit
+lokalen Bibliotheken zu binden. Um Referenzen auf Bibliotheken außerhalb des
+Stores zu erlauben, müssen Sie die Umgebungsvariable
+@code{GUIX_LD_WRAPPER_ALLOW_IMPURITIES} setzen.
+
+@c TODO What else?

+@chapter Paketverwaltung
+
+@cindex Pakete
+Der Zweck von GNU Guix ist, Benutzern die leichte Installation,
+Aktualisierung und Entfernung von Software-Paketen zu ermöglichen, ohne dass
+sie ihre Erstellungsprozeduren oder Abhängigkeiten kennen müssen. Guix kann
+natürlich noch mehr als diese offensichtlichen Funktionalitäten.

+Dieses Kapitel beschreibt die Hauptfunktionalitäten von Guix, sowie die von
+Guix angebotenen Paketverwaltungswerkzeuge. Zusätzlich von den im Folgenden
+beschriebenen Befehlszeilen-Benutzerschnittstellen (@pxref{Aufruf von guix package, @code{guix package}}) können Sie auch mit der
+Emacs-Guix-Schnittstelle (@pxref{Top,,, emacs-guix, The Emacs-Guix Reference
+Manual}) arbeiten, nachdem Sie das Paket @code{emacs-guix} installiert haben
+(führen Sie zum Einstieg in Emacs-Guix den Emacs-Befehl @kbd{M-x guix-help}
+aus):

+@node Funktionalitäten
+@section Funktionalitäten
+
+Wenn Sie Guix benutzen, landet jedes Paket schließlich im @dfn{Paket-Store}
+in seinem eigenen Verzeichnis — der Name ist ähnlich wie
+@file{/gnu/store/xxx-package-1.2}, wobei @code{xxx} eine Zeichenkette in
+Base32-Darstellung ist.
+
+Statt diese Verzeichnisse direkt anzugeben, haben Nutzer ihr eigenes
+@dfn{Profil}, welches auf diejenigen Pakete zeigt, die sie tatsächlich
+benutzen wollen. Diese Profile sind im Persönlichen Ordner des jeweiligen
+Nutzers gespeichert als @code{$HOME/.guix-profile}.
+
+Zum Beispiel installiert @code{alice} GCC 4.7.2. Dadurch zeigt dann
+@file{/home/alice/.guix-profile/bin/gcc} auf
+@file{/gnu/store/@dots{}-gcc-4.7.2/bin/gcc}. Auf demselben Rechner hat
+@code{bob} bereits GCC 4.8.0 installiert. Das Profil von @code{bob} zeigt
+dann einfach weiterhin auf @file{/gnu/store/@dots{}-gcc-4.8.0/bin/gcc} —
+d.h. beide Versionen von GCC koexistieren auf demselben System, ohne sich zu
+stören.
+
+Der Befehl @command{guix package} ist das zentrale Werkzeug, um Pakete zu
+verwalten (@pxref{Aufruf von guix package}). Es arbeitet auf dem eigenen
+Profil jedes Nutzers und kann @emph{mit normalen Benutzerrechten} ausgeführt
+werden.
+
+@cindex Transaktionen
+Der Befehl stellt die offensichtlichen Installations-, Entfernungs- und
+Aktualisierungsoperationen zur Verfügung. Jeder Aufruf ist tatsächlich eine
+eigene @emph{Transaktion}: Entweder die angegebene Operation wird
+erfolgreich durchgeführt, oder gar nichts passiert. Wenn also der Prozess
+von @command{guix package} während der Transaktion beendet wird, oder es zum
+Stromausfall während der Transaktion kommt, dann bleibt der alte, nutzbare
+Zustands des Nutzerprofils erhalten.
+
+Zudem kann jede Pakettransaktion @emph{zurückgesetzt} werden
+(Rollback). Wird also zum Beispiel durch eine Aktualisierung eine neue
+Version eines Pakets installiert, die einen schwerwiegenden Fehler zur Folge
+hat, können Nutzer ihr Profil einfach auf die vorherige Profilinstanz
+zurücksetzen, von der sie wissen, dass sie gut lief. Ebenso unterliegt auf
+GuixSD auch die globale Systemkonfiguration transaktionellen
+Aktualisierungen und Rücksetzungen (@pxref{Das Konfigurationssystem nutzen}).
+
+Alle Pakete im Paket-Store können vom @emph{Müllsammler} (Garbage Collector)
+gelöscht werden. Guix ist in der Lage, festzustellen, welche Pakete noch
+durch Benutzerprofile referenziert werden, und entfernt nur diese, die
+nachweislich nicht mehr referenziert werden (@pxref{Aufruf von guix gc}). Benutzer können auch ausdrücklich alte Generationen ihres Profils
+löschen, damit die zugehörigen Pakete vom Müllsammler gelöscht werden
+können.
+
+@cindex Reproduzierbarkeit
+@cindex Reproduzierbare Erstellungen
+Guix takes a @dfn{purely functional} approach to package management, as
+described in the introduction (@pxref{Einführung}).  Each
+@file{/gnu/store} package directory name contains a hash of all the inputs
+that were used to build that package---compiler, libraries, build scripts,
+etc.  This direct correspondence allows users to make sure a given package
+installation matches the current state of their distribution.  It also helps
+maximize @dfn{build reproducibility}: thanks to the isolated build
+environments that are used, a given build is likely to yield bit-identical
+files when performed on different machines (@pxref{Aufruf des guix-daemon,
+container}).
+
+@cindex Substitute
+Auf dieser Grundlage kann Guix @dfn{transparent Binär- oder Quelldateien
+ausliefern}. Wenn eine vorerstellte Binärdatei für ein
+@file{/gnu/store}-Objekt von einer externen Quelle verfügbar ist — ein
+@dfn{Substitut} —, lädt Guix sie einfach herunter und entpackt sie,
+andernfalls erstellt Guix das Paket lokal aus seinem Quellcode
+(@pxref{Substitute}). Weil Erstellungsergebnisse normalerweise Bit für Bit
+reproduzierbar sind, müssen die Nutzer den Servern, die Substitute anbieten,
+nicht blind vertrauen; sie können eine lokale Erstellung erzwingen und
+Substitute @emph{anfechten} (@pxref{Aufruf von guix challenge}).
+
+Kontrolle über die Erstellungsumgebung ist eine auch für Entwickler
+nützliche Funktionalität. Der Befehl @command{guix environment} ermöglicht
+es Entwicklern eines Pakets, schnell die richtige Entwicklungsumgebung für
+ihr Paket einzurichten, ohne manuell die Abhängigkeiten des Pakets in ihr
+Profil installieren zu müssen (@pxref{Aufruf von guix environment}).
+
+@cindex replication, of software environments
+@cindex provenance tracking, of software artifacts
+All of Guix and its package definitions is version-controlled, and
+@command{guix pull} allows you to ``travel in time'' on the history of Guix
+itself (@pxref{Aufruf von guix pull}).  This makes it possible to replicate a
+Guix instance on a different machine or at a later point in time, which in
+turn allows you to @emph{replicate complete software environments}, while
+retaining precise @dfn{provenance tracking} of the software.
+
+@node Aufruf von guix package
+@section Invoking @command{guix package}
+
+@cindex Installieren von Paketen
+@cindex Entfernen von Paketen
+@cindex Paketinstallation
+@cindex Paketentfernung
+Der Befehl @command{guix package} ist ein Werkzeug, womit Nutzer Pakete
+installieren, aktualisieren, entfernen und auf vorherige Konfigurationen
+zurücksetzen können. Dabei wird nur das eigene Profil des Nutzers verwendet,
+und es funktioniert mit normalen Benutzerrechten, ohne Administratorrechte
+(@pxref{Funktionalitäten}). Die Syntax ist:
+
+@example
+guix package @var{Optionen}
+@end example
+@cindex Transaktionen
+In erster Linie geben die @var{Optionen} an, welche Operationen in der
+Transaktion durchgeführt werden sollen. Nach Abschluss wird ein neues Profil
+erzeugt, aber vorherige @dfn{Generationen} des Profils bleiben verfügbar,
+falls der Benutzer auf sie zurückwechseln will.
+
+Um zum Beispiel @code{lua} zu entfernen und @code{guile} und
+@code{guile-cairo} in einer einzigen Transaktion zu installieren:
+
+@example
+guix package -r lua -i guile guile-cairo
+@end example
+
+@command{guix package} unterstützt auch ein @dfn{deklaratives Vorgehen},
+wobei der Nutzer die genaue Menge an Paketen, die verfügbar sein sollen,
+festlegt und über die Befehlszeilenoption @option{--manifest} übergibt
+(@pxref{profile-manifest, @option{--manifest}}).
+
+@cindex Profil
+Für jeden Benutzer wird automatisch eine symbolische Verknüpfung zu seinem
+Standardprofil angelegt als @file{$HOME/.guix-profile}. Diese symbolische
+Verknüpfung zeigt immer auf die aktuelle Generation des Standardprofils des
+Benutzers. Somit können Nutzer @file{$HOME/.guix-profile/bin} z.B. zu ihrer
+Umgebungsvariablen @code{PATH} hinzufügen.
+@cindex Suchpfade
+Wenn Sie nicht die Guix System Distribution benutzen, sollten Sie in
+Betracht ziehen, folgende Zeilen zu Ihrem @file{~/.bash_profile}
+hinzuzufügen (@pxref{Bash Startup Files,,, bash, The GNU Bash Reference
+Manual}), damit in neu erzeugten Shells alle Umgebungsvariablen richtig
+definiert werden:
+
+@example
+GUIX_PROFILE="$HOME/.guix-profile" ; \
+source "$HOME/.guix-profile/etc/profile"
+@end example
+
+Ist Ihr System für mehrere Nutzer eingerichtet, werden Nutzerprofile an
+einem Ort gespeichert, der als @dfn{Müllsammlerwurzel} registriert ist, auf
+die @file{$HOME/.guix-profile} zeigt (@pxref{Aufruf von guix gc}). Dieses
+Verzeichnis ist normalerweise
+@code{@var{localstatedir}/guix/profiles/per-user/@var{Benutzer}}, wobei
+@var{localstatedir} der an @code{configure} als @code{--localstatedir}
+übergebene Wert ist und @var{Benutzer} für den jeweiligen Benutzernamen
+steht. Das @file{per-user}-Verzeichnis wird erstellt, wenn
+@command{guix-daemon} gestartet wird, und das Unterverzeichnis
+@var{Benutzer} wird durch @command{guix package} erstellt.
+
+Als @var{Optionen} kann vorkommen:
+
+@table @code
+
+@item --install=@var{Paket} @dots{}
+@itemx -i @var{Paket} @dots{}
+Die angegebenen @var{Paket}e installieren.
+
+Jedes @var{Paket} kann entweder einfach durch seinen Paketnamen aufgeführt
+werden, wie @code{guile}, oder als Paketname gefolgt von einem At-Zeichen @@
+und einer Versionsnummer, wie @code{guile@@1.8.8} oder auch nur
+@code{guile@@1.8} (in letzterem Fall wird die neueste Version mit Präfix
+@code{1.8} ausgewählt.)
+
+Wird keine Versionsnummer angegeben, wird die neueste verfügbare Version
+ausgewählt. Zudem kann im @var{Paket} ein Doppelpunkt auftauchen, gefolgt
+vom Namen einer der Ausgaben des Pakets, wie @code{gcc:doc} oder
+@code{binutils@@2.22:lib} (@pxref{Pakete mit mehreren Ausgaben.}). Pakete
+mit zugehörigem Namen (und optional der Version) werden unter den Modulen
+der GNU-Distribution gesucht (@pxref{Paketmodule}).
+
+@cindex propagierte Eingaben
+Manchmal haben Pakete @dfn{propagierte Eingaben}: Als solche werden
+Abhängigkeiten bezeichnet, die automatisch zusammen mit dem angeforderten
+Paket installiert werden (im Abschnitt @pxref{package-propagated-inputs,
+@code{propagated-inputs} in @code{package} objects} sind weitere
+Informationen über propagierte Eingaben in Paketdefinitionen zu finden).
+
+@anchor{package-cmd-propagated-inputs}
+Ein Beispiel ist die GNU-MPC-Bibliothek: Ihre C-Headerdateien verweisen auf
+die der GNU-MPFR-Bibliothek, welche wiederum auf die der GMP-Bibliothek
+verweisen. Wenn also MPC installiert wird, werden auch die MPFR- und
+GMP-Bibliotheken in das Profil installiert; entfernt man MPC, werden auch
+MPFR und GMP entfernt — außer sie wurden noch auf andere Art ausdrücklich
+vom Nutzer installiert.
+
+Abgesehen davon setzen Pakete manchmal die Definition von Umgebungsvariablen
+für ihre Suchpfade voraus (siehe die Erklärung von @code{--search-paths}
+weiter unten). Alle fehlenden oder womöglich falschen Definitionen von
+Umgebungsvariablen werden hierbei gemeldet.
+
+@item --install-from-expression=@var{Ausdruck}
+@itemx -e @var{Ausdruck}
+Das Paket installieren, zu dem der @var{Ausdruck} ausgewertet wird.
+
+Beim @var{Ausdruck} muss es sich um einen Scheme-Ausdruck handeln, der zu
+einem @code{<package>}-Objekt ausgewertet wird. Diese Option ist besonders
+nützlich, um zwischen gleichnamigen Varianten eines Pakets zu unterscheiden,
+durch Ausdrücke wie @code{(@@ (gnu packages base) guile-final)}.
+
+Beachten Sie, dass mit dieser Option die erste Ausgabe des angegebenen
+Pakets installiert wird, was unzureichend sein kann, wenn eine bestimmte
+Ausgabe eines Pakets mit mehreren Ausgaben gewünscht ist.
+
+@item --install-from-file=@var{Datei}
+@itemx -f @var{Datei}
+Das Paket installieren, zu dem der Code in der @var{Datei} ausgewertet wird.
+
+Zum Beispiel könnte die @var{Datei} eine Definition wie diese enthalten
+(@pxref{Pakete definieren}):
+
+@example
+@verbatiminclude package-hello.scm
+@end example
+
+Entwickler könnten es für nützlich erachten, eine solche
+@file{guix.scm}-Datei im Quellbaum ihres Projekts abzulegen, mit der
+Zwischenstände der Entwicklung getestet und reproduzierbare
+Erstellungsumgebungen aufgebaut werden können (@pxref{Aufruf von guix environment}).
+
+@item --remove=@var{Paket} @dots{}
+@itemx -r @var{Paket} @dots{}
+Die angegebenen @var{Paket}e entfernen.
+
+Wie auch bei @code{--install} kann jedes @var{Paket} neben dem Paketnamen
+auch eine Versionsnummer und/oder eine Ausgabe benennen. Zum Beispiel würde
+@code{-r glibc:debug} die @code{debug}-Ausgabe von @code{glibc} aus dem
+Profil entfernen.
+
+@item --upgrade[=@var{Regexp} @dots{}]
+@itemx -u [@var{Regexp} @dots{}]
+@cindex Pakete aktualisieren
+Alle installierten Pakete aktualisieren. Wenn einer oder mehr reguläre
+Ausdrücke (Regexps) angegeben wurden, werden nur diejenigen installierten
+Pakete aktualisiert, deren Name zu einer der @var{Regexp}s passt. Siehe auch
+weiter unten die Befehlszeilenoption @code{--do-not-upgrade}.
+
+Beachten Sie, dass das Paket so auf die neueste Version unter den Paketen
+gebracht wird, die in der aktuell installierten Distribution vorliegen. Um
+jedoch Ihre Distribution zu aktualisieren, sollten Sie regelmäßig
+@command{guix pull} ausführen (@pxref{Aufruf von guix pull}).
+
+@item --do-not-upgrade[=@var{Regexp} @dots{}]
+In Verbindung mit der Befehlszeilenoption @code{--upgrade}, führe
+@emph{keine} Aktualisierung von Paketen durch, deren Name zum regulären
+Ausdruck @var{Regexp} passt. Um zum Beispiel alle Pakete im aktuellen Profil
+zu aktualisieren mit Ausnahme derer, die »emacs« im Namen haben:
+
+@example
+$ guix package --upgrade . --do-not-upgrade emacs
+@end example
+
+@item @anchor{profile-manifest}--manifest=@var{Datei}
+@itemx -m @var{Datei}
+@cindex Profildeklaration
+@cindex Profilmanifest
+Erstellt eine neue Generation des Profils aus dem vom Scheme-Code in
+@var{Datei} gelieferten Manifest-Objekt.
+
+Dadurch könnrn Sie den Inhalt des Profils @emph{deklarieren}, statt ihn
+durch eine Folge von Befehlen wie @code{--install} u.Ä. zu generieren. Der
+Vorteil ist, dass die @var{Datei} unter Versionskontrolle gestellt werden
+kann, auf andere Maschinen zum Reproduzieren desselben Profils kopiert
+werden kann und Ähnliches.
+
+@c FIXME: Add reference to (guix profile) documentation when available.
+Der Code in der @var{Datei} muss ein @dfn{Manifest}-Objekt liefern, was
+ungefähr einer Liste von Paketen entspricht:
+
+@findex packages->manifest
+@example
+(use-package-modules guile emacs)
+
+(packages->manifest
+ (list emacs
+       guile-2.0
+       ;; Eine bestimmte Paketausgabe nutzen.
+       (list guile-2.0 "debug")))
+@end example
+
+@findex specifications->manifest
+In diesem Beispiel müssen wir wissen, welche Module die Variablen
+@code{emacs} und @code{guile-2.0} definieren, um die richtige Angabe mit
+@code{use-package-modules} machen zu können, was umständlich sein kann. Wir
+können auch normale Paketnamen angeben und sie durch
+@code{specifications->manifest} zu den entsprechenden Paketobjekten
+auflösen, zum Beispiel so:
+
+@example
+(specifications->manifest
+ '("emacs" "guile@@2.2" "guile@@2.2:debug"))
+@end example
+
+@item --roll-back
+@cindex rücksetzen
+@cindex Zurücksetzen von Transaktionen
+@cindex Transaktionen, zurücksetzen
+Wechselt zur vorherigen @dfn{Generation} des Profils zurück — d.h. macht die
+letzte Transaktion rückgängig.
+
+In Verbindung mit Befehlszeilenoptionen wie @code{--install} wird zuerst
+zurückgesetzt, bevor andere Aktionen durchgeführt werden.
+
+Ein Rücksetzen der ersten Generation, die installierte Pakete enthält,
+wechselt das Profil zur @dfn{nullten Generation}, die keinerlei Dateien
+enthält, abgesehen von Metadaten über sich selbst.
+
+Nach dem Zurücksetzen überschreibt das Installieren, Entfernen oder
+Aktualisieren von Paketen vormals zukünftige Generationen, d.h. der Verlauf
+der Generationen eines Profils ist immer linear.
+
+@item --switch-generation=@var{Muster}
+@itemx -S @var{Muster}
+@cindex Generationen
+Wechselt zu der bestimmten Generation, die durch das @var{Muster} bezeichnet
+wird.
+
+Als @var{Muster} kann entweder die Nummer einer Generation oder eine Nummer
+mit vorangestelltem »+« oder »-« dienen. Letzteres springt die angegebene
+Anzahl an Generationen vor oder zurück. Zum Beispiel kehrt
+@code{--switch-generation=+1} nach einem Zurücksetzen wieder zur neueren
+Generation zurück.
+
+Der Unterschied zwischen @code{--roll-back} und
+@code{--switch-generation=-1} ist, dass @code{--switch-generation} keine
+nullte Generation erzeugen wird; existiert die angegebene Generation nicht,
+bleibt schlicht die aktuelle Generation erhalten.
+
+@item --search-paths[=@var{Art}]
+@cindex Suchpfade
+Führe die Definitionen von Umgebungsvariablen auf, in Bash-Syntax, die nötig
+sein könnten, um alle installierten Pakete nutzen zu können. Diese
+Umgebungsvariablen werden benutzt, um die @dfn{Suchpfade} für Dateien
+festzulegen, die von einigen installierten Paketen benutzt werden.
+
+Zum Beispiel braucht GCC die Umgebungsvariablen @code{CPATH} und
+@code{LIBRARY_PATH}, um zu wissen, wo sich im Benutzerprofil Header und
+Bibliotheken befinden (@pxref{Environment Variables,,, gcc, Using the GNU
+Compiler Collection (GCC)}). Wenn GCC und, sagen wir, die C-Bibliothek im
+Profil installiert sind, schlägt @code{--search-paths} also vor, diese
+Variablen jeweils auf @code{@var{profile}/include} und
+@code{@var{profile}/lib} verweisen zu lassen.
+
+Die typische Nutzung ist, in der Shell diese Variablen zu definieren:
+
+@example
+$ eval `guix package --search-paths`
+@end example
+
+Als @var{Art} kann entweder @code{exact}, @code{prefix} oder @code{suffix}
+gewählt werden, wodurch die gelieferten Definitionen der Umgebungsvariablen
+entweder exakt die Einstellungen für Guix meldet, oder sie als Präfix oder
+Suffix an den aktuellen Wert dieser Variablen anhängt. Gibt man keine
+@var{Art} an, wird der Vorgabewert @code{exact} verwendet.
+
+Diese Befehlszeilenoption kann auch benutzt werden, um die
+@emph{kombinierten} Suchpfade mehrerer Profile zu berechnen. Betrachten Sie
+dieses Beispiel:
+
+@example
+$ guix package -p foo -i guile
+$ guix package -p bar -i guile-json
+$ guix package -p foo -p bar --search-paths
+@end example
+
+Der letzte Befehl oben meldet auch die Definition der Umgebungsvariablen
+@code{GUILE_LOAD_PATH}, obwohl für sich genommen weder @file{foo} noch
+@file{bar} zu dieser Empfehlung führen würden.
+
+
+@item --profile=@var{Profil}
+@itemx -p @var{Profil}
+Auf @var{Profil} anstelle des Standardprofils des Benutzers arbeiten.
+
+@cindex Kollisionen, in einem Profil
+@cindex Paketkollisionen in Profilen
+@cindex Profilkollisionen
+@item --allow-collisions
+Kollidierende Pakete im neuen Profil zulassen. Benutzung auf eigene Gefahr!
+
+Standardmäßig wird @command{guix package} @dfn{Kollisionen} als Fehler
+auffassen und melden. Zu Kollisionen kommt es, wenn zwei oder mehr
+verschiedene Versionen oder Varianten desselben Pakets im Profil landen.
+
+@item --verbose
+Erzeugt ausführliche Textausgaben. Insbesondere wird auch das
+Erstellungsprotokoll der Umgebung auf dem Standard-Fehler-Port (stderr)
+ausgegeben.
+
+@item --bootstrap
+Erstellt das Profil mit dem Bootstrap-Guile. Diese Option ist nur für
+Entwickler der Distribution nützlich.
+
+@end table
+
+Zusätzlich zu diesen Aktionen unterstützt @command{guix package} folgende
+Befehlszeilenoptionen, um den momentanen Zustand eines Profils oder die
+Verfügbarkeit von Paketen nachzulesen:
+
+@table @option
+
+@item --search=@var{Regexp}
+@itemx -s @var{Regexp}
+@cindex Suche nach Paketen
+Führt alle verfügbaren Pakete auf, deren Name, Zusammenfassung oder
+Beschreibung zum regulären Ausdruck @var{Regexp} passt, sortiert nach ihrer
+Relevanz. Alle Metadaten passender Pakete werden im @code{recutils}-Format
+geliefert (@pxref{Top, GNU recutils databases,, recutils, GNU recutils
+manual}).
+
+So können bestimmte Felder mit dem Befehl @command{recsel} extrahiert
+werden, zum Beispiel:
+
+@example
+$ guix package -s malloc | recsel -p name,version,relevance
+name: jemalloc
+version: 4.5.0
+relevance: 6
+
+name: glibc
+version: 2.25
+relevance: 1
+
+name: libgc
+version: 7.6.0
+relevance: 1
+@end example
+
+Ebenso kann der Name aller zu den Bedingungen der GNU@tie{}LGPL, Version 3,
+verfügbaren Pakete ermittelt werden:
+
+@example
+$ guix package -s "" | recsel -p name -e 'license ~ "LGPL 3"'
+name: elfutils
+
+name: gmp
+@dots{}
+@end example
+
+Es ist auch möglich, Suchergebnisse näher einzuschränken, indem Sie
+@code{-s} mehrmals übergeben. Zum Beispiel liefert folgender Befehl eines
+Liste von Brettspielen:
+
+@example
+$ guix package -s '\<board\>' -s game | recsel -p name
+name: gnubg
+@dots{}
+@end example
+
+Würden wir @code{-s game} weglassen, bekämen wir auch Software-Pakete
+aufgelistet, die mit »printed circuit boards« (elektronischen Leiterplatten)
+zu tun haben; ohne die spitzen Klammern um @code{board} bekämen wir auch
+Pakete, die mit »keyboards« (Tastaturen, oder musikalischen Keyboard) zu tun
+haben.
+
+Es ist Zeit für ein komplexeres Beispiel. Folgender Befehl sucht
+kryptographische Bibliotheken, filtert Haskell-, Perl-, Python- und
+Ruby-Bibliotheken heraus und gibt Namen und Zusammenfassung passender Pakete
+aus:
+
+@example
+$ guix package -s crypto -s library | \
+    recsel -e '! (name ~ "^(ghc|perl|python|ruby)")' -p name,synopsis
+@end example
+
+@noindent
+@xref{Selection Expressions,,, recutils, GNU recutils manual} enthält
+weitere Informationen über @dfn{Auswahlausdrücke} mit @code{recsel -e}.
+
+@item --show=@var{Paket}
+Zeigt Details über das @var{Paket} aus der Liste verfügbarer Pakete, im
+@code{recutils}-Format (@pxref{Top, GNU recutils databases,, recutils, GNU
+recutils manual}).
+
+@example
+$ guix package --show=python | recsel -p name,version
+name: python
+version: 2.7.6
+
+name: python
+version: 3.3.5
+@end example
+
+Sie können auch den vollständigen Namen eines Pakets angeben, um Details nur
+über diese Version angezeigt zu bekommen:
+@example
+$ guix package --show=python@@3.4 | recsel -p name,version
+name: python
+version: 3.4.3
+@end example
+
+
+
+@item --list-installed[=@var{Regexp}]
+@itemx -I [@var{Regexp}]
+Listet die derzeit installierten Pakete im angegebenen Profil auf, die
+zuletzt installierten Pakete zuletzt. Wenn ein regulärer Ausdruck
+@var{Regexp} angegeben wird, werden nur installierte Pakete aufgeführt,
+deren Name zu @var{Regexp} passt.
+
+Zu jedem installierten Paket werden folgende Informationen angezeigt, durch
+Tabulatorzeichen getrennt: der Paketname, die Version als Zeichenkette,
+welche Teile des Pakets installiert sind (zum Beispiel @code{out}, wenn die
+Standard-Paketausgabe installiert ist, @code{include}, wenn seine Header
+installiert sind, usw.) und an welchem Pfad das Paket im Store zu finden
+ist.
+
+@item --list-available[=@var{Regexp}]
+@itemx -A [@var{Regexp}]
+Listet Pakete auf, die in der aktuell installierten Distribution dieses
+Systems verfügbar sind (@pxref{GNU-Distribution}). Wenn ein regulärer
+Ausdruck @var{Regexp} angegeben wird, werden nur Pakete aufgeführt, deren
+Name zum regulären Ausdruck @var{Regexp} passt.
+
+Zu jedem Paket werden folgende Informationen getrennt durch Tabulatorzeichen
+ausgegeben: der Name, die Version als Zeichenkette, die Teile des Programms
+(@pxref{Pakete mit mehreren Ausgaben.}) und die Stelle im Quellcode, an der
+das Paket definiert ist.
+
+@item --list-generations[=@var{Muster}]
+@itemx -l [@var{Muster}]
+@cindex Generationen
+Liefert eine Liste der Generationen zusammen mit dem Datum, an dem sie
+erzeugt wurden; zu jeder Generation werden zudem die installierten Pakete
+angezeigt, zuletzt installierte Pakete zuletzt. Beachten Sie, dass die
+nullte Generation niemals angezeigt wird.
+
+Zu jedem installierten Paket werden folgende Informationen durch
+Tabulatorzeichen getrennt angezeigt: der Name des Pakets, die Version als
+Zeichenkette, welcher Teil des Pakets installiert ist (@pxref{Pakete mit mehreren Ausgaben.}) und an welcher Stelle sich das Paket im Store befindet.
+
+Wenn ein @var{Muster} angegeben wird, liefert der Befehl nur dazu passende
+Generationen. Gültige Muster sind zum Beispiel:
+
+@itemize
+@item @emph{Ganze Zahlen und kommagetrennte ganze Zahlen}. Beide Muster bezeichnen
+Generationsnummern. Zum Beispiel liefert @code{--list-generations=1} die
+erste Generation.
+
+Durch @code{--list-generations=1,8,2} werden drei Generationen in der
+angegebenen Reihenfolge angezeigt. Weder Leerzeichen noch ein Komma am
+Schluss der Liste ist erlaubt.
+
+@item @emph{Bereiche}. @code{--list-generations=2..9} gibt die
+angegebenen Generationen und alles dazwischen aus. Beachten Sie, dass der
+Bereichsanfang eine kleinere Zahl als das Bereichsende sein muss.
+
+Sie können auch kein Bereichsende angeben, zum Beispiel liefert
+@code{--list-generations=2..} alle Generationen ab der zweiten.
+
+@item @emph{Zeitdauern}. Sie können auch die letzten @emph{N}@tie{}Tage, Wochen
+or months by passing an integer along with the first letter of the
+duration.  For example, @code{--list-generations=20d} lists generations that
+are up to 20 days old.
+@end itemize
+
+@item --delete-generations[=@var{Muster}]
+@itemx -d [@var{Muster}]
+Wird kein @var{Muster} angegeben, werden alle Generationen außer der
+aktuellen entfernt.
+
+Dieser Befehl akzeptiert dieselben Muster wie
+@option{--list-generations}. Wenn ein @var{Muster} angegeben wird, werden
+die passenden Generationen gelöscht. Wenn das @var{Muster} für eine
+Zeitdauer steht, werden diejenigen Generationen gelöscht, die @emph{älter}
+als die angegebene Dauer sind. Zum Beispiel löscht
+@code{--delete-generations=1m} die Generationen, die mehr als einen Monat
+alt sind.
+
+Falls die aktuelle Generation zum Muster passt, wird sie @emph{nicht}
+gelöscht. Auch die nullte Generation wird niemals gelöscht.
+

+@cindex Hydra
+@cindex Build-Farm
+Der Server @code{mirror.hydra.gnu.org} ist die Façade für eine offizielle
+»Build-Farm«, ein Erstellungswerk, das kontinuierlich Guix-Pakete für einige
+Prozessorarchitekturen erstellt und sie als Substitute zur Verfügung
+stellt. Dies ist die standardmäßige Quelle von Substituten; durch Übergeben
+der Befehlszeilenoption @option{--substitute-urls} an entweder den
+@command{guix-daemon} (@pxref{daemon-substitute-urls,, @code{guix-daemon
+--substitute-urls}}) oder Client-Werkzeuge wie @command{guix package}
+(@pxref{client-substitute-urls,, client @option{--substitute-urls} option})
+kann eine abweichende Einstellung benutzt werden.
+
+Substitut-URLs können entweder HTTP oder HTTPS sein. HTTPS wird empfohlen,
+weil die Kommunikation verschlüsselt ist; umgekehrt kann bei HTTP die
+Kommunikation belauscht werden, wodurch der Angreifer zum Beispiel erfahren
+könnte, ob Ihr System über noch nicht behobene Sicherheitsschwachstellen
+verfügt.
+
+Substitute von der offiziellen Build-Farm sind standardmäßig erlaubt, wenn
+Sie die Guix-System-Distribution verwenden (@pxref{GNU-Distribution}). Auf
+Fremddistributionen sind sie allerdings standardmäßig ausgeschaltet, solange
+Sie sie nicht ausdrücklich in einem der empfohlenen Installationsschritte
+erlaubt haben (@pxref{Installation}). Die folgenden Absätze beschreiben, wie
+Sie Substitute für die offizielle Build-Farm an- oder ausschalten; dieselbe
+Prozedur kann auch benutzt werden, um Substitute für einen beliebigen
+anderen Substitutsserver zu erlauben.

+@cindex Access Control List (ACL), für Substitute
+@cindex ACL (Access Control List), für Substitute
+Um es Guix zu gestatten, Substitute von @code{hydra.gnu.org} oder einem
+Spiegelserver davon herunterzuladen, müssen Sie den zugehörigen öffentlichen
+Schlüssel zur Access Control List (ACL, Zugriffssteuerungsliste) für
+Archivimporte hinzufügen, mit Hilfe des Befehls @command{guix archive}
+(@pxref{Aufruf von guix archive}). Dies impliziert, dass Sie darauf vertrauen,
+dass @code{hydra.gnu.org} nicht kompromittiert wurde und echte Substitute
+liefert.
+
+Der öffentliche Schlüssel für @code{hydra.gnu.org} wird zusammen mit Guix
+installiert, in das Verzeichnis
+@code{@var{prefix}/share/guix/hydra.gnu.org.pub}, wobei @var{prefix} das
+Installationspräfix von Guix ist. Wenn Sie Guix aus seinem Quellcode heraus
+installieren, stellen Sie sicher, dass Sie die GPG-Signatur von
+@file{guix-@value{VERSION}.tar.gz} prüfen, worin sich dieser öffentliche
+Schlüssel befindet. Dann können Sie so etwas wie hier ausführen:
+
+@example
+# guix archive --authorize < @var{prefix}/share/guix/hydra.gnu.org.pub
+@end example
+
+@quotation Anmerkung
+Genauso enthält die Datei @file{berlin.guixsd.org.pub} den öffentlichen
+Schlüssel für die neue Build-Farm des Guix-Projekts, die unter
+@indicateurl{https://berlin.guixsd.org} erreichbar ist.
+
+Derzeit, als dieser Text geschrieben wurde, wird @code{berlin.guixsd.org}
+ausgebaut, um besser skalieren zu können, aber Sie könnten es
+ausprobieren. Dahinter stecken 20 x86_64-/i686-Erstellungsknoten, die
+Substitute früher anbieten könnten als @code{mirror.hydra.gnu.org}.
+@end quotation
+
+Sobald es eingerichtet wurde, sollte sich die Ausgabe eines Befehls wie
+@code{guix build} von so etwas:
+
+@example
+$ guix build emacs --dry-run
+Folgende Ableitungen würden erstellt:
+   /gnu/store/yr7bnx8xwcayd6j95r2clmkdl1qh688w-emacs-24.3.drv

+@dots{}
+@end example
+
+@noindent
+Das zeigt an, dass Substitute von @code{hydra.gnu.org} nutzbar sind und für
+zukünftige Erstellungen heruntergeladen werden, wann immer es möglich ist.
+
+@cindex Substitute, wie man sie ausschaltet
+Der Substitutsmechanismus kann global ausgeschaltet werden, indem Sie dem
+@code{guix-daemon} beim Starten die Befehlszeilenoption
+@code{--no-substitutes} übergeben (@pxref{Aufruf des guix-daemon}). Er kann
+auch temporär ausgeschaltet werden, indem Sie @code{--no-substitutes} an
+@command{guix package}, @command{guix build} und andere
+Befehlszeilenwerkzeuge übergeben.
+
+@node Substitutauthentifizierung
+@subsection Substitutauthentifizierung
+
+@cindex digitale Signaturen
+Guix erkennt, wenn ein verfälschtes Substitut benutzt würde, und meldet
+einen Fehler. Ebenso werden Substitute ignoriert, die nich signiert sind,
+oder nicht mit einem in der ACL aufgelisteten Schlüssel signiert sind.
+
+Es gibt nur eine Ausnahme: Wenn ein unautorisierter Server Substitute
+anbietet, die @emph{Bit für Bit identisch} mit denen von einem autorisierten
+Server sind, können sie auch vom unautorisierten Server heruntergeladen
+werden. Zum Beispiel, angenommen wir haben zwei Substitutserver mit dieser
+Befehlszeilenoption ausgewählt:
+
+@example
+--substitute-urls="https://a.example.org https://b.example.org"
+@end example
+
+@noindent
+@cindex Reproduzierbare Erstellungen
+Wenn in der ACL nur der Schlüssel für @code{b.example.org} aufgeführt wurde,
+aber @code{a.example.org} @emph{exakt dieselben} Substitute anbietet, wird
+Guix auch Substitute von @code{a.example.org} herunterladen, weil es in der
+Liste zuerst kommt und als Spiegelserver für @code{b.example.org} aufgefasst
+werden kann. In der Praxis haben unabhängige Maschinen bei der Erstellung
+normalerweise dieselben Binärdateien als Ergebnis, dank bit-reproduzierbarer
+Erstellungen (siehe unten).
+
+Wenn Sie HTTPS benutzen, wird das X.509-Zertifikat des Servers @emph{nicht}
+validiert (mit anderen Worten, die Identität des Servers wird nicht
+authentifiziert), entgegen dem, was HTTPS-Clients wie Web-Browser
+normalerweise tun. Da Guix Substitutinformationen selbst überprüft, wie oben
+erklärt, wäre es unnötig (wohingegen mit X.509-Zertifikaten geprüft wird, ob
+ein Domain-Name zu öffentlichen Schlüsseln passt).
+
+@node Proxy-Einstellungen
+@subsection Proxy-Einstellungen
+
+@vindex http_proxy
+Substitute werden über HTTP oder HTTPS heruntergeladen. Die
+Umgebungsvariable @code{http_proxy} kann in der Umgebung von
+@command{guix-daemon} definiert werden und wirkt sich dann auf das
+Herunterladen von Substituten aus. Beachten Sie, dass der Wert von
+@code{http_proxy} in der Umgebung, in der @command{guix build},
+@command{guix package} und andere Client-Befehle ausgeführt werden,
+@emph{keine Rolle spielt}.
+
+@node Fehler bei der Substitution
+@subsection Fehler bei der Substitution
+
+Selbst wenn ein Substitut für eine Ableitung verfügbar ist, schlägt die
+versuchte Substitution manchmal fehl. Das kann aus vielen Gründen geschehen:
+die Substitutsserver könnten offline sein, das Substitut könnte kürzlich
+gelöscht worden sein, die Netzwerkverbindunge könnte unterbrochen worden
+sein, usw.
+
+Wenn Substitute aktiviert sind und ein Substitut für eine Ableitung zwar
+verfügbar ist, aber die versuchte Substitution fehlschlägt, kann Guix
+versuchen, die Ableitung lokal zu erstellen, je nachdem, ob
+@code{--fallback} übergeben wurde (@pxref{fallback-option,, common build
+option @code{--fallback}}). Genauer gesagt, wird keine lokale Erstellung
+durchgeführt, solange kein @code{--fallback} angegeben wurde, und die
+Ableitung wird als Fehlschlag angesehen. Wenn @code{--fallback} übergeben
+wurde, wird Guix versuchen, die Ableitung lokal zu erstellen, und ob die
+Ableitung erfolgreich ist oder nicht, hängt davon ab, ob die lokale
+Erstellung erfolgreich ist oder nicht. Beachten Sie, dass, falls Substitute
+ausgeschaltet oder erst gar kein Substitut verfügbar ist, @emph{immer} eine
+lokale Erstellung durchgeführt wird, egal ob @code{--fallback} übergeben
+wurde oder nicht.
+
+Um eine Vorstellung zu bekommen, wieviele Substitute gerade verfügbar sind,
+können Sie den Befehl @command{guix weather} benutzen (@pxref{Aufruf von guix weather}). Dieser Befehl zeigt Statistiken darüber an, wie es um die von
+einem Server verfügbaren Substitute steht.
+
+@node Vom Vertrauen gegenüber Binärdateien
+@subsection Vom Vertrauen gegenüber Binärdateien
+
+@cindex Vertrauen, gegenüber vorerstellten Binärdateien
+Derzeit hängt die Kontrolle jedes Individuums über seine Rechner von
+Institutionen, Unternehmen und solchen Gruppierungen ab, die über genug
+Macht und Entschlusskraft verfügen, die Rechnerinfrastruktur zu sabotieren
+und ihre Schwachstellen auszunutzen. Auch wenn es bequem ist, Substitute von
+@code{hydra.gnu.org} zu benutzen, ermuntern wir Nutzer, auch selbst
+Erstellungen durchzuführen oder gar ihre eigene Build-Farm zu betreiben,
+damit @code{hydra.gnu.org} ein weniger interessantes Ziel wird. Eine Art,
+uns zu helfen, ist, die von Ihnen erstellte Software mit dem Befehl
+@command{guix publish} zu veröffentlichen, damit andere eine größere Auswahl
+haben, von welchem Server sie Substitute beziehen möchten (@pxref{Aufruf von guix publish}).
+
+Guix hat die richtigen Grundlagen, um die Reproduzierbarkeit von
+Erstellungen zu maximieren (@pxref{Funktionalitäten}). In den meisten Fällen sollten
+unabhängige Erstellungen eines bestimmten Pakets zu bitweise identischen
+Ergebnissen führen. Wir können also mit Hilfe einer vielschichtigen Menge an
+unabhängigen Paketerstellungen die Integrität unseres Systems besser
+gewährleisten. Der Befehl @command{guix challenge} hat das Ziel, Nutzern zu
+ermöglichen, Substitutserver zu beurteilen, und Entwickler dabei zu
+unterstützen, nichtdeterministische Paketerstellungen zu finden
+(@pxref{Aufruf von guix challenge}). Ebenso ermöglicht es die
+Befehlszeilenoption @option{--check} von @command{guix build}, dass Nutzer
+bereits installierte Substitute auf Echtheit zu prüfen, indem sie lokal
+nachgebaut werden (@pxref{build-check, @command{guix build --check}}).
+
+In Zukunft wollen wir, dass Guix Binärdateien an und von Nutzern
+peer-to-peer veröffentlichen kann. Wenn Sie mit uns dieses Projekt
+diskuttieren möchten, kommen Sie auf unsere Mailing-Liste

+@node Pakete mit mehreren Ausgaben.
+@section Pakete mit mehreren Ausgaben.
+
+@cindex mehrere Ausgaben, bei Paketen
+@cindex Paketausgaben
+@cindex Ausgaben
+
+Oft haben in Guix definierte Pakete eine einzige @dfn{Ausgabe} — d.h. aus
+dem Quellpaket entsteht genau ein Verzeichnis im Store. Wenn Sie
+@command{guix package -i glibc} ausführen, wird die Standard-Paketausgabe
+des GNU-libc-Pakets installiert; die Standardausgabe wird @code{out}
+genannt, aber ihr Name kann weggelassen werden, wie sie an obigem Befehl
+sehen. In diesem speziellen Fall enthält die Standard-Paketausgabe von
+@code{glibc} alle C-Headerdateien, gemeinsamen Bibliotheken (»Shared
+Libraries«), statische Bibliotheken (»Static Libraries«), Dokumentation für
+Info sowie andere zusätzliche Dateien.
+
+Manchmal ist es besser, die verschiedenen Arten von Dateien, die aus einem
+einzelnen Quellpaket hervorgehen, in getrennte Ausgaben zu unterteilen. Zum
+Beispiel installiert die GLib-C-Bibliothek (die von GTK+ und damit
+zusammenhängenden Paketen benutzt wird) mehr als 20 MiB an HTML-Seiten mit
+Referenzdokumentation. Um den Nutzern, die das nicht brauchen, Platz zu
+sparen, wird die Dokumentation in einer separaten Ausgabe abgelegt, genannt
+@code{doc}. Um also die Hauptausgabe von GLib zu installieren, zu der alles
+außer der Dokumentation gehört, ist der Befehl:
+
+@example
+guix package -i glib
+@end example
+
+@cindex Dokumentation
+Der Befehl, um die Dokumentation zu installieren, ist:
+
+@example
+guix package -i glib:doc
+@end example
+
+Manche Pakete installieren Programme mit unterschiedlich großem
+»Abhängigkeiten-Fußabdruck«. Zum Beispiel installiert das Paket WordNet
+sowohl Befehlszeilenwerkzeuge als auch grafische Benutzerschnittstellen
+(GUIs). Erstere hängen nur von der C-Bibliothek ab, während Letztere auch
+von Tcl/Tk und den zu Grunde liegenden X-Bibliotheken abhängen. Jedenfalls
+belassen wir deshalb die Befehlszeilenwerkzeuge in der
+Standard-Paketausgabe, während sich die GUIs in einer separaten Ausgabe
+befinden. So können Benutzer, die die GUIs nicht brauchen, Platz sparen. Der
+Befehl @command{guix size} kann dabei helfen, solche Situationen zu erkennen
+(@pxref{Aufruf von guix size}). @command{guix graph} kann auch helfen
+(@pxref{Aufruf von guix graph}).
+
+In der GNU-Distribution gibt es viele solche Pakete mit mehreren
+Ausgaben. Andere Konventionen für Ausgabenamen sind zum Beispiel @code{lib}
+für Bibliotheken und eventuell auch ihre Header-Dateien,, @code{bin} für
+eigenständige Programme und @code{debug} für Informationen zur
+Fehlerbehandlung (@pxref{Dateien zur Fehlersuche installieren}). Die Ausgaben eines
+Pakets stehen in der dritten Spalte der Anzeige von @command{guix package
+--list-available} (@pxref{Aufruf von guix package}).

+
+@cindex Müllsammler
+@cindex Plattenspeicher
+Pakete, die zwar installiert sind, aber nicht benutzt werden, können vom
+@dfn{Müllsammler} entfernt werden. Mit dem Befehl @command{guix gc} können
+Benutzer den Müllsammler ausdrücklich aufrufen, um Speicher im Verzeichnis
+@file{/gnu/store} freizugeben. Dies ist der @emph{einzige} Weg, Dateien aus
+@file{/gnu/store} zu entfernen — das manuelle Entfernen von Dateien kann den
+Store irreparabel beschädigen!
+
+@cindex GC-Wurzeln
+@cindex Müllsammlerwurzeln
+Der Müllsammler kennt eine Reihe von @dfn{Wurzeln}: Jede Datei in
+@file{/gnu/store}, die von einer Wurzel aus erreichbar ist, gilt als
+@dfn{lebendig} und kann nicht entfernt werden; jede andere Datei gilt als
+@dfn{tot} und ist ein Kandidat, gelöscht zu werden. Die Menge der
+Müllsammlerwurzeln (kurz auch »GC-Wurzeln«, von englisch »Garbage
+Collector«) umfasst Standard-Benutzerprofile; standardmäßig werden diese
+Müllsammlerwurzeln durch symbolische Verknüpfungen in
+@file{/var/guix/gcroots} dargestellt. Neue Müllsammlerwurzeln können zum
+Beispiel mit @command{guix build --root} festgelegt werden (@pxref{Aufruf von guix build}).
+
+Bevor Sie mit @code{guix gc --collect-garbage} Speicher freimachen, wollen
+Sie vielleicht alte Generationen von Benutzerprofilen löschen, damit alte
+Paketerstellungen von diesen Generationen entfernt werden können. Führen Sie
+dazu @code{guix package --delete-generations} aus (@pxref{Aufruf von guix package}).
+
+Unsere Empfehlung ist, dass Sie den Müllsammler regelmäßig laufen lassen und
+wenn Sie wenig freien Speicherplatz zur Verfügung haben. Um zum Beispiel
+sicherzustellen, dass Sie mindestens 5@tie{}GB auf Ihrer Platte zur
+Verfügung haben, benutzen Sie einfach:
+
+@example
+guix gc -F 5G
+@end example
+
+Es ist völlig sicher, dafür eine nicht interaktive, regelmäßige
+Auftragsausführung vorzugeben (@pxref{Geplante Auftragsausführung}, für eine
+Erklärung, wie man das in GuixSD tun kann). @command{guix gc} ohne
+Befehlszeilenargumente auszuführen, lässt so viel Müll wie möglich sammeln,
+aber das ist oft nicht, was man will, denn so muss man unter Umständen
+Software erneut erstellen oder erneut herunterladen, weil der Müllsammler
+sie als »tot« ansieht, sie aber zur Erstellung anderer Software wieder
+gebraucht wird — das trifft zum Beispiel auf die Compiler-Toolchain zu.
+
+Der Befehl @command{guix gc} hat drei Arbeitsmodi: Er kann benutzt werden,
+um als Müllsammler tote Dateien zu entfernen (das Standardverhalten), um
+ganz bestimmte, angegebene Datein zu löschen (mit der Befehlszeilenoption
+@code{--delete}), um Müllsammlerinformationen auszugeben oder
+fortgeschrittenere Anfragen zu verarbeiten. Die
+Müllsammler-Befehlszeilenoptionen sind wie folgt:
+
+@table @code
+@item --collect-garbage[=@var{Minimum}]
+@itemx -C [@var{Minimum}]
+Lässt Müll sammeln — z.B. nicht erreichbare Dateien in @file{/gnu/store} und
+seinen Unterverzeichnissen. Wird keine andere Befehlszeilenoption angegeben,
+wird standardmäßig diese durchgeführt.
+
+Wenn ein @var{Minimum} angegeben wurde, hört der Müllsammler auf, sobald
+@var{Minimum} Bytes gesammelt wurden. Das @var{Minimum} kann die Anzahl der
+Bytes bezeichnen oder mit einer Einheit als Suffix versehen sein, wie etwa
+@code{MiB} für Mebibytes und @code{GB} für Gigabytes (@pxref{Block size,
+size specifications,, coreutils, GNU Coreutils}).
+
+Wird kein @var{Minimum} angegeben, sammelt der Müllsammler allen Müll.
+
+@item --free-space=@var{Menge}
+@itemx -F @var{Menge}
+Sammelt Müll, bis die angegebene @var{Menge} an freiem Speicher in
+@file{/gnu/store} zur Verfügung steht, falls möglich; die @var{Menge} ist
+eine Speichergröße wie @code{500MiB}, wie oben beschrieben.
+
+Wenn die angegebene  @var{Menge} oder mehr bereits in @file{/gnu/store} frei
+verfügbar ist, passiert nichts.
+
+@item --delete
+@itemx -d
+Versucht, alle als Argumente angegebenen Dateien oder Verzeichnisse im Store
+zu löschen. Dies schlägt fehl, wenn manche der Dateien oder Verzeichnisse
+nicht im Store oder noch immer lebendig sind.
+
+@item --list-failures
+Store-Objekte auflisten, die zwischengespeicherten Erstellungsfehlern
+entsprechen.
+
+Hierbei wird nichts ausgegeben, sofern der Daemon nicht mit
+@option{--cache-failures} gestartet wurde (@pxref{Aufruf des guix-daemon,
+@option{--cache-failures}}).
+
+@item --clear-failures
+Die angegebenen Store-Objekte aus dem Zwischenspeicher für fehlgeschlagene
+Erstellungen entfernen.
+
+Auch diese Option macht nur Sinn, wenn der Daemon mit
+@option{--cache-failures} gestartet wurde. Andernfalls passiert nichts.
+
+@item --list-dead
+Zeigt die Liste toter Dateien und Verzeichnisse an, die sich noch im Store
+befinden — das heißt, Dateien, die von keiner Wurzel mehr erreichbar sind.
+
+@item --list-live
+Zeige die Liste lebendiger Store-Dateien und -Verzeichnisse.
+

+@cindex Paketabhängigkeiten
+Listet die referenzierten bzw. sie referenzierenden Objekte der angegebenen

+@cindex Abschluss
+Listet alle Voraussetzungen der als Argumente übergebenen Store-Dateien
+auf. Voraussetzungen sind die Store-Dateien selbst, ihre Referenzen sowie

+Liste ist der @dfn{transitive Abschluss} dieser Store-Dateien.
+
+Der Abschnitt @xref{Aufruf von guix size} erklärt ein Werkzeug, um den
+Speicherbedarf des Abschlusses eines Elements zu ermitteln. Siehe

+veranschaulichen.
+
+@item --derivers
+@cindex Ableitung
+Liefert die Ableitung(en), die zu den angegebenen Store-Objekten führen
+(@pxref{Ableitungen}).
+
+Zum Beispiel liefert dieser Befehl:
+
+@example
+guix gc --derivers `guix package -I ^emacs$ | cut -f4`
+@end example
+
+@noindent
+die @file{.drv}-Datei(en), die zum in Ihrem Profil installierten
+@code{emacs}-Paket führen.
+
+Beachten Sie, dass es auch sein kann, dass keine passenden
+@file{.drv}-Dateien existieren, zum Beispiel wenn diese Dateien bereits dem
+Müllsammler zum Opfer gefallen sind. Es kann auch passieren, dass es mehr
+als eine passende @file{.drv} gibt, bei Ableitungen mit fester Ausgabe.
+@end table
+
+Zuletzt können Sie mit folgenden Befehlszeilenoptionen die Integrität des
+Stores prüfen und den Plattenspeicherverbrauch im Zaum halten.
+
+@table @option
+
+@item --verify[=@var{Optionen}]
+@cindex Integrität, des Stores
+@cindex Integritätsprüfung
+Die Integrität des Stores verifizieren
+
+Standardmäßig wird sichergestellt, dass alle Store-Objekte, die in der
+Datenbank des Daemons als gültig markiert wurden, auch tatsächlich in
+@file{/gnu/store} existieren.
+
+Wenn angegeben, müssen die @var{Optionen} eine kommagetrennte Liste aus
+mindestens einem der Worte @code{contents} und @code{repair} sein.
+
+Wenn Sie @option{--verify=contents} übergeben, berechnet der Daemon den Hash
+des Inhalts jedes Store-Objekts und vergleicht ihn mit dem Hash in der
+Datenbank. Sind die Hashes ungleich, wird eine Datenbeschädigung
+gemeldet. Weil dabei @emph{alle Dateien im Store} durchlaufen werden, kann
+der Befehl viel Zeit brauchen, besonders auf Systemen mit langsamer Platte.
+
+@cindex Store, reparieren
+@cindex Datenbeschädigung, Behebung
+Mit @option{--verify=repair} oder @option{--verify=contents,repair} versucht
+der Daemon, beschädigte Store-Objekte zu reparieren, indem er Substitute für
+selbige herunterlädt (@pxref{Substitute}). Weil die Reparatur nicht atomar
+und daher womöglich riskant ist, kann nur der Systemadministrator den Befehl
+benutzen. Eine weniger aufwendige Alternative, wenn Sie wissen, welches
+Objekt beschädigt ist, ist, @command{guix build --repair} zu benutzen
+(@pxref{Aufruf von guix build}).
+
+@item --optimize
+@cindex Deduplizieren
+Den Store durch Nutzung harter Verknüpfungen für identische Dateien
+optimieren — mit anderen Worten wird der Store @dfn{dedupliziert}.
+
+Der Daemon führt Deduplizierung automatisch nach jeder erfolgreichen
+Erstellung und jedem Importieren eines Archivs durch, sofern er nicht mit
+@code{--disable-deduplication} (@pxref{Aufruf des guix-daemon,
+@code{--disable-deduplication}}) gestartet wurde. Diese Befehlszeilenoption

+@cindex configuration file for channels
+@cindex @command{guix pull}, configuration file
+@cindex configuration of @command{guix pull}
+Guix and its package collection are updated by running @command{guix pull}
+(@pxref{Aufruf von guix pull}).  By default @command{guix pull} downloads and
+deploys Guix itself from the official GNU@tie{}Guix repository.  This can be
+customized by defining @dfn{channels} in the
+@file{~/.config/guix/channels.scm} file.  A channel specifies a URL and
+branch of a Git repository to be deployed, and @command{guix pull} can be
+instructed to pull from one or more channels.  In other words, channels can
+be used to @emph{customize} and to @emph{extend} Guix, as we will see below.
+
+@subsection Using a Custom Guix Channel
+
+The channel called @code{guix} specifies where Guix itself---its
+command-line tools as well as its package collection---should be
+downloaded.  For instance, suppose you want to update from your own copy of
+the Guix repository at @code{example.org}, and specifically the
+@code{super-hacks} branch, you can write in
+@code{~/.config/guix/channels.scm} this specification:
+
+@lisp
+;; Tell 'guix pull' to use my own repo.
+(list (channel
+        (name 'guix)
+        (url "https://example.org/my-guix.git")
+        (branch "super-hacks")))
+@end lisp
+
+@noindent
+From there on, @command{guix pull} will fetch code from the
+@code{super-hacks} branch of the repository at @code{example.org}.
+
+@subsection Specifying Additional Channels
+
+@cindex extending the package collection (channels)
+@cindex personal packages (channels)
+@cindex channels, for personal packages
+You can also specify @emph{additional channels} to pull from.  Let's say you
+have a bunch of custom package variants or personal packages that you think
+would make little sense to contribute to the Guix project, but would like to
+have these packages transparently available to you at the command line.  You
+would first write modules containing those package definitions
+(@pxref{Paketmodule}), maintain them in a Git repository, and then you
+and anyone else can use it as an additional channel to get packages from.
+Neat, no?
+
+@c What follows stems from discussions at
+@c <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=22629#134> as well as
+@c earlier discussions on guix-devel@gnu.org.
+@quotation Warning
+Before you, dear user, shout---``woow this is @emph{soooo coool}!''---and
+publish your personal channel to the world, we would like to share a few
+words of caution:
+
+@itemize
+@item
+Before publishing a channel, please consider contributing your package
+definitions to Guix proper (@pxref{Mitwirken}).  Guix as a project is
+open to free software of all sorts, and packages in Guix proper are readily
+available to all Guix users and benefit from the project's quality assurance
+process.
+
+@item
+When you maintain package definitions outside Guix, we, Guix developers,
+consider that @emph{the compatibility burden is on you}.  Remember that
+package modules and package definitions are just Scheme code that uses
+various programming interfaces (APIs).  We want to remain free to change
+these APIs to keep improving Guix, possibly in ways that break your
+channel.  We never change APIs gratuitously, but we will @emph{not} commit
+to freezing APIs either.
+
+@item
+Corollary: if you're using an external channel and that channel breaks,
+please @emph{report the issue to the channel authors}, not to the Guix
+project.
+@end itemize
+
+You've been warned! Having said this, we believe external channels are a
+practical way to exert your freedom to augment Guix' package collection and
+to share your improvements, which are basic tenets of
+@uref{https://www.gnu.org/philosophy/free-sw.html, free software}.  Please
+email us at @email{guix-devel@@gnu.org} if you'd like to discuss this.
+@end quotation
+
+Once you have a Git repository containing your own package modules, you can
+write @code{~/.config/guix/channels.scm} to instruct @command{guix pull} to
+pull from your personal channel @emph{in addition} to the default Guix
+channel(s):
+
+@vindex %default-channels
+@lisp
+;; Add my personal packages to those Guix provides.
+(cons (channel
+        (name 'my-personal-packages)
+        (url "https://example.org/personal-packages.git"))
+      %default-channels)
+@end lisp
+
+@noindent
+Note that the snippet above is (as always!)@: Scheme code; we use
+@code{cons} to add a channel the list of channels that the variable
+@code{%default-channels} is bound to (@pxref{Pairs, @code{cons} and lists,,
+guile, GNU Guile Reference Manual}).  With this file in place, @command{guix
+pull} builds not only Guix but also the package modules from your own
+repository.  The result in @file{~/.config/guix/current} is the union of
+Guix with your own package modules:
+
+@example
+$ guix pull --list-generations
+@dots{}

+The output of @command{guix pull} above shows that Generation@tie{}19
+includes both Guix and packages from the @code{my-personal-packages}
+channel.  Among the new and upgraded packages that are listed, some like
+@code{my-gimp} and @code{my-emacs-with-cool-features} might come from
+@code{my-personal-packages}, while others come from the Guix default
+channel.
+
+@subsection Replicating Guix
+
+@cindex pinning, channels
+@cindex replicating Guix
+@cindex reproducibility, of Guix
+The @command{guix pull --list-generations} output above shows precisely
+which commits were used to build this instance of Guix.  We can thus
+replicate it, say, on another machine, by providing a channel specification
+in @file{~/.config/guix/channels.scm} that is ``pinned'' to these commits:
+
+@lisp
+;; Deploy specific commits of my channels of interest.
+(list (channel
+       (name 'guix)
+       (url "https://git.savannah.gnu.org/git/guix.git")
+       (commit "d894ab8e9bfabcefa6c49d9ba2e834dd5a73a300"))
+      (channel
+       (name 'my-personal-packages)
+       (url "https://example.org/personal-packages.git")
+       (branch "dd3df5e2c8818760a8fc0bd699e55d3b69fef2bb")))
+@end lisp
+
+The @command{guix describe --format=channels} command can even generate this
+list of channels directly (@pxref{Invoking guix describe}).
+
+At this point the two machines run the @emph{exact same Guix}, with access
+to the @emph{exact same packages}.  The output of @command{guix build gimp}
+on one machine will be exactly the same, bit for bit, as the output of the
+same command on the other machine.  It also means both machines have access
+to all the source code of Guix and, transitively, to all the source code of
+every package it defines.
+
+This gives you super powers, allowing you to track the provenance of binary
+artifacts with very fine grain, and to reproduce software environments at
+will---some sort of ``meta reproducibility'' capabilities, if you will.
+@xref{Inferiors}, for another way to take advantage of these super powers.
+

+@section Inferiors
+
+@c TODO: Remove this once we're more confident about API stability.

+@end quotation
+
+@cindex inferiors
+@cindex composition of Guix revisions
+Sometimes you might need to mix packages from the revision of Guix you're
+currently running with packages available in a different revision of Guix.
+Guix @dfn{inferiors} allow you to achieve that by composing different Guix
+revisions in arbitrary ways.
+
+@cindex inferior packages
+Technically, an ``inferior'' is essentially a separate Guix process
+connected to your main Guix process through a REPL (@pxref{Invoking guix
+repl}).  The @code{(guix inferior)} module allows you to create inferiors
+and to communicate with them.  It also provides a high-level interface to
+browse and manipulate the packages that an inferior provides---@dfn{inferior
+packages}.
+
+When combined with channels (@pxref{Channels}), inferiors provide a simple
+way to interact with a separate revision of Guix.  For example, let's assume
+you want to install in your profile the current @code{guile} package, along
+with the @code{guile-json} as it existed in an older revision of
+Guix---perhaps because the newer @code{guile-json} has an incompatible API
+and you want to run your code against the old API@.  To do that, you could
+write a manifest for use by @code{guix package --manifest} (@pxref{Aufruf von guix package}); in that manifest, you would create an inferior for that old
+Guix revision you care about, and you would look up the @code{guile-json}
+package in the inferior:
+
+@lisp
+(use-modules (guix inferior) (guix channels)
+             (srfi srfi-1))   ;for 'first'
+
+(define channels
+  ;; This is the old revision from which we want to
+  ;; extract guile-json.
+  (list (channel
+         (name 'guix)
+         (url "https://git.savannah.gnu.org/git/guix.git")
+         (commit
+          "65956ad3526ba09e1f7a40722c96c6ef7c0936fe"))))
+
+(define inferior
+  ;; An inferior representing the above revision.
+  (inferior-for-channels channels))
+
+;; Now create a manifest with the current "guile" package
+;; and the old "guile-json" package.
+(packages->manifest
+ (list (first (lookup-inferior-packages inferior "guile-json"))
+       (specification->package "guile")))
+@end lisp
+
+On its first run, @command{guix package --manifest} might have to build the
+channel you specified before it can create the inferior; subsequent runs
+will be much faster because the Guix revision will be cached.
+
+The @code{(guix inferior)} module provides the following procedures to open
+an inferior:
+
+@deffn {Scheme Procedure} inferior-for-channels @var{channels} @
+   [#:cache-directory] [#:ttl] Return an inferior for @var{channels}, a list of
+channels.  Use the cache at @var{cache-directory}, where entries can be
+reclaimed after @var{ttl} seconds.  This procedure opens a new connection to
+the build daemon.
+
+As a side effect, this procedure may build or substitute binaries for
+@var{channels}, which can take time.
+@end deffn
+
+@deffn {Scheme Procedure} open-inferior @var{directory} @
+  [#:command "bin/guix"] Open the inferior Guix in @var{directory}, running
+@code{@var{directory}/@var{command} repl} or equivalent.  Return @code{#f}
+if the inferior could not be launched.
+@end deffn
+
+@cindex inferior packages
+The procedures listed below allow you to obtain and manipulate inferior
+packages.
+
+@deffn {Scheme Procedure} inferior-packages @var{inferior}
+Return the list of packages known to @var{inferior}.
+@end deffn
+
+@deffn {Scheme Procedure} lookup-inferior-packages @var{inferior} @var{name} @
+   [@var{version}] Return the sorted list of inferior packages matching
+@var{name} in @var{inferior}, with highest version numbers first.  If
+@var{version} is true, return only packages with a version number prefixed
+by @var{version}.
+@end deffn
+
+@deffn {Scheme Procedure} inferior-package? @var{obj}
+Return true if @var{obj} is an inferior package.
+@end deffn
+
+@deffn {Scheme Procedure} inferior-package-name @var{package}
+@deffnx {Scheme Procedure} inferior-package-version @var{package}
+@deffnx {Scheme Procedure} inferior-package-synopsis @var{package}
+@deffnx {Scheme Procedure} inferior-package-description @var{package}
+@deffnx {Scheme Procedure} inferior-package-home-page @var{package}

+@deffnx {Scheme Procedure} inferior-package-inputs @var{package}
+@deffnx {Scheme Procedure} inferior-package-native-inputs @var{package}
+@deffnx {Scheme Procedure} inferior-package-propagated-inputs @var{package}
+@deffnx {Scheme Procedure} inferior-package-transitive-propagated-inputs @var{package}
+@deffnx {Scheme Procedure} inferior-package-native-search-paths @var{package}
+@deffnx {Scheme Procedure} inferior-package-transitive-native-search-paths @var{package}
+@deffnx {Scheme Procedure} inferior-package-search-paths @var{package}
+These procedures are the counterpart of package record accessors
+(@pxref{„package“-Referenz}).  Most of them work by querying the inferior
+@var{package} comes from, so the inferior must still be live when you call
+these procedures.
+@end deffn
+
+Inferior packages can be used transparently like any other package or
+file-like object in G-expressions (@pxref{G-Ausdrücke}).  They are also
+transparently handled by the @code{packages->manifest} procedure, which is
+commonly use in manifests (@pxref{Aufruf von guix package, the
+@option{--manifest} option of @command{guix package}}).  Thus you can insert
+an inferior package pretty much anywhere you would insert a regular package:
+in manifests, in the @code{packages} field of your @code{operating-system}
+declaration, and so on.

+@cindex replicating Guix
+Often you may want to answer questions like: ``Which revision of Guix am I
+using?'' or ``Which channels am I using?'' This is useful information in
+many situations: if you want to @emph{replicate} an environment on a
+different machine or user account, if you want to report a bug or to
+determine what change in the channels you are using caused it, or if you
+want to record your system state for reproducibility purposes.  The
+@command{guix describe} command answers these questions.
+
+When run from a @command{guix pull}ed @command{guix}, @command{guix
+describe} displays the channel(s) that it was built from, including their
+repository URL and commit IDs (@pxref{Channels}):
+

+@end example
+
+If you're familiar with the Git version control system, this is similar in
+spirit to @command{git describe}; the output is also similar to that of
+@command{guix pull --list-generations}, but limited to the current
+generation (@pxref{Aufruf von guix pull, the @option{--list-generations}
+option}).  Because the Git commit ID shown above unambiguously refers to a
+snapshot of Guix, this information is all it takes to describe the revision
+of Guix you're using, and also to replicate it.
+
+To make it easier to replicate Guix, @command{guix describe} can also be
+asked to return a list of channels instead of the human-readable description
+above:
+
+@example
+$ guix describe -f channels
+(list (channel

+@end example
+
+@noindent
+You can save this to a file and feed it to @command{guix pull -C} on some
+other machine or at a later point in time, which will instantiate @emph{this
+exact Guix revision} (@pxref{Aufruf von guix pull, the @option{-C} option}).
+From there on, since you're able to deploy the same revision of Guix, you
+can just as well @emph{replicate a complete software environment}.  We

+Occasionally you want to pass software to people who are not (yet!)  lucky

+@command{guix pack} comes in.
+
+@quotation Anmerkung
+If you are looking for ways to exchange binaries among machines that already

+@ref{Aufruf von guix archive}.
+@end quotation
+
+@cindex pack
+@cindex bundle
+@cindex application bundle
+@cindex software bundle
+The @command{guix pack} command creates a shrink-wrapped @dfn{pack} or
+@dfn{software bundle}: it creates a tarball or some other archive containing
+the binaries of the software you're interested in, and all its
+dependencies.  The resulting archive can be used on any machine that does
+not have Guix, and people can run the exact same binaries as those you have
+with Guix.  The pack itself is created in a bit-reproducible fashion, so
+anyone can verify that it really contains the build results that you pretend
+to be shipping.
+
+For example, to create a bundle containing Guile, Emacs, Geiser, and all
+their dependencies, you can run:
+
+@example
+$ guix pack guile emacs geiser
+@dots{}
+/gnu/store/@dots{}-pack.tar.gz
+@end example
+
+The result here is a tarball containing a @file{/gnu/store} directory with
+all the relevant packages.  The resulting tarball contains a @dfn{profile}
+with the three packages of interest; the profile is the same as would be
+created by @command{guix package -i}.  It is this mechanism that is used to
+create Guix's own standalone binary tarball (@pxref{Aus Binärdatei installieren}).
+
+Users of this pack would have to run
+@file{/gnu/store/@dots{}-profile/bin/guile} to run Guile, which you may find
+inconvenient.  To work around it, you can create, say, a @file{/opt/gnu/bin}
+symlink to the profile:
+
+@example
+guix pack -S /opt/gnu/bin=bin guile emacs geiser
+@end example
+
+@noindent
+That way, users can happily type @file{/opt/gnu/bin/guile} and enjoy.
+
+@cindex relocatable binaries, with @command{guix pack}
+What if the recipient of your pack does not have root privileges on their
+machine, and thus cannot unpack it in the root file system? In that case,
+you will want to use the @code{--relocatable} option (see below).  This
+option produces @dfn{relocatable binaries}, meaning they they can be placed
+anywhere in the file system hierarchy: in the example above, users can
+unpack your tarball in their home directory and directly run
+@file{./opt/gnu/bin/guile}.
+
+@cindex Docker, build an image with guix pack
+Alternatively, you can produce a pack in the Docker image format using the
+following command:
+
+@example
+guix pack -f docker guile emacs geiser
+@end example
+
+@noindent
+The result is a tarball that can be passed to the @command{docker load}
+command.  See the
+@uref{https://docs.docker.com/engine/reference/commandline/load/, Docker
+documentation} for more information.
+
+@cindex Singularity, build an image with guix pack
+@cindex SquashFS, build an image with guix pack
+Yet another option is to produce a SquashFS image with the following
+command:
+
+@example
+guix pack -f squashfs guile emacs geiser
+@end example
+
+@noindent
+The result is a SquashFS file system image that can either be mounted or
+directly be used as a file system container image with the
+@uref{http://singularity.lbl.gov, Singularity container execution
+environment}, using commands like @command{singularity shell} or
+@command{singularity exec}.
+
+Several command-line options allow you to customize your pack:
+
+@table @code
+@item --format=@var{format}
+@itemx -f @var{format}
+Produce a pack in the given @var{format}.
+
+The available formats are:
+
+@table @code
+@item tarball
+This is the default format.  It produces a tarball containing all the
+specified binaries and symlinks.
+
+@item docker
+This produces a tarball that follows the
+@uref{https://github.com/docker/docker/blob/master/image/spec/v1.2.md,
+Docker Image Specification}.
+
+@item squashfs
+This produces a SquashFS image containing all the specified binaries and
+symlinks, as well as empty mount points for virtual file systems like
+procfs.
+@end table
+
+@item --relocatable
+@itemx -R
+Produce @dfn{relocatable binaries}---i.e., binaries that can be placed
+anywhere in the file system hierarchy and run from there.  For example, if
+you create a pack containing Bash with:
+
+@example
+guix pack -R -S /mybin=bin bash
+@end example
+
+@noindent
+...@: you can copy that pack to a machine that lacks Guix, and from your
+home directory as a normal user, run:
+
+@example
+tar xf pack.tar.gz
+./mybin/sh
+@end example
+
+@noindent
+In that shell, if you type @code{ls /gnu/store}, you'll notice that
+@file{/gnu/store} shows up and contains all the dependencies of @code{bash},
+even though the machine actually lacks @file{/gnu/store} altogether! That is
+probably the simplest way to deploy Guix-built software on a non-Guix
+machine.
+
+There's a gotcha though: this technique relies on the @dfn{user namespace}
+feature of the kernel Linux, which allows unprivileged users to mount or
+change root.  Old versions of Linux did not support it, and some GNU/Linux
+distributions turn it off; on these systems, programs from the pack
+@emph{will fail to run}, unless they are unpacked in the root file system.
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Consider the package @var{expr} evaluates to.
+
+This has the same purpose as the same-named option in @command{guix build}
+(@pxref{Zusätzliche Erstellungsoptionen, @code{--expression} in @command{guix
+build}}).
+
+@item --manifest=@var{Datei}
+@itemx -m @var{Datei}
+Use the packages contained in the manifest object returned by the Scheme
+code in @var{file}.
+
+This has a similar purpose as the same-named option in @command{guix
+package} (@pxref{profile-manifest, @option{--manifest}}) and uses the same
+manifest files.  It allows you to define a collection of packages once and
+use it both for creating profiles and for creating archives for use on
+machines that do not have Guix installed.  Note that you can specify
+@emph{either} a manifest file @emph{or} a list of packages, but not both.
+
+@item --system=@var{System}
+@itemx -s @var{system}
+Attempt to build for @var{system}---e.g., @code{i686-linux}---instead of the
+system type of the build host.
+
+@item --target=@var{triplet}
+@cindex cross-compilation
+Cross-build for @var{triplet}, which must be a valid GNU triplet, such as
+@code{"mips64el-linux-gnu"} (@pxref{Specifying target triplets, GNU
+configuration triplets,, autoconf, Autoconf}).
+
+@item --compression=@var{tool}
+@itemx -C @var{tool}
+Compress the resulting tarball using @var{tool}---one of @code{gzip},
+@code{bzip2}, @code{xz}, @code{lzip}, or @code{none} for no compression.
+
+@item --symlink=@var{spec}
+@itemx -S @var{spec}
+Add the symlinks specified by @var{spec} to the pack.  This option can
+appear several times.
+
+@var{spec} has the form @code{@var{source}=@var{target}}, where @var{source}
+is the symlink that will be created and @var{target} is the symlink target.
+
+For instance, @code{-S /opt/gnu/bin=bin} creates a @file{/opt/gnu/bin}
+symlink pointing to the @file{bin} sub-directory of the profile.
+
+@item --localstatedir
+@itemx --profile-name=@var{name}
+Include the ``local state directory'', @file{/var/guix}, in the resulting
+pack, and notably the @file{/var/guix/profiles/per-user/root/@var{name}}
+profile---by default @var{name} is @code{guix-profile}, which corresponds to
+@file{~root/.guix-profile}.
+
+@file{/var/guix} contains the store database (@pxref{Der Store}) as well as
+garbage-collector roots (@pxref{Aufruf von guix gc}).  Providing it in the
+pack means that the store is ``complete'' and manageable by Guix; not
+providing it pack means that the store is ``dead'': items cannot be added to
+it or removed from it after extraction of the pack.
+
+One use case for this is the Guix self-contained binary tarball
+(@pxref{Aus Binärdatei installieren}).
+
+@item --bootstrap
+Use the bootstrap binaries to build the pack.  This option is only useful to
+Guix developers.
+@end table
+
+In addition, @command{guix pack} supports all the common build options
+(@pxref{Gemeinsame Erstellungsoptionen}) and all the package transformation options
+(@pxref{Paketumwandlungsoptionen}).
+
+
+@node Aufruf von guix archive
+@section Invoking @command{guix archive}
+
+@cindex @command{guix archive}
+@cindex archive
+The @command{guix archive} command allows users to @dfn{export} files from
+the store into a single archive, and to later @dfn{import} them on a machine
+that runs Guix.  In particular, it allows store files to be transferred from
+one machine to the store on another machine.
+
+@quotation Anmerkung
+If you're looking for a way to produce archives in a format suitable for
+tools other than Guix, @pxref{Aufruf von guix pack}.
+@end quotation
+
+@cindex exporting store items
+To export store files as an archive to standard output, run:
+
+@example
+guix archive --export @var{options} @var{specifications}...
+@end example
+
+@var{specifications} may be either store file names or package
+specifications, as for @command{guix package} (@pxref{Aufruf von guix package}).  For instance, the following command creates an archive
+containing the @code{gui} output of the @code{git} package and the main
+output of @code{emacs}:
+
+@example
+guix archive --export git:gui /gnu/store/...-emacs-24.3 > great.nar
+@end example
+
+If the specified packages are not built yet, @command{guix archive}
+automatically builds them.  The build process may be controlled with the
+common build options (@pxref{Gemeinsame Erstellungsoptionen}).
+
+To transfer the @code{emacs} package to a machine connected over SSH, one
+would run:
+
+@example
+guix archive --export -r emacs | ssh the-machine guix archive --import
+@end example
+
+@noindent
+Similarly, a complete user profile may be transferred from one machine to
+another like this:
+
+@example
+guix archive --export -r $(readlink -f ~/.guix-profile) | \
+  ssh the-machine guix-archive --import
+@end example
+
+@noindent
+However, note that, in both examples, all of @code{emacs} and the profile as
+well as all of their dependencies are transferred (due to @code{-r}),
+regardless of what is already available in the store on the target machine.
+The @code{--missing} option can help figure out which items are missing from
+the target store.  The @command{guix copy} command simplifies and optimizes
+this whole process, so this is probably what you should use in this case
+(@pxref{Aufruf von guix copy}).
+
+@cindex nar, archive format
+@cindex normalized archive (nar)
+Archives are stored in the ``normalized archive'' or ``nar'' format, which
+is comparable in spirit to `tar', but with differences that make it more
+appropriate for our purposes.  First, rather than recording all Unix
+metadata for each file, the nar format only mentions the file type (regular,
+directory, or symbolic link); Unix permissions and owner/group are
+dismissed.  Second, the order in which directory entries are stored always
+follows the order of file names according to the C locale collation order.
+This makes archive production fully deterministic.
+
+@c FIXME: Add xref to daemon doc about signatures.
+When exporting, the daemon digitally signs the contents of the archive, and
+that digital signature is appended.  When importing, the daemon verifies the
+signature and rejects the import in case of an invalid signature or if the
+signing key is not authorized.
+
+The main options are:
+
+@table @code
+@item --export
+Export the specified store files or packages (see below.)  Write the
+resulting archive to the standard output.
+
+Dependencies are @emph{not} included in the output, unless
+@code{--recursive} is passed.
+
+@item -r
+@itemx --recursive
+When combined with @code{--export}, this instructs @command{guix archive} to
+include dependencies of the given items in the archive.  Thus, the resulting
+archive is self-contained: it contains the closure of the exported store
+items.
+
+@item --import
+Read an archive from the standard input, and import the files listed therein
+into the store.  Abort if the archive has an invalid digital signature, or
+if it is signed by a public key not among the authorized keys (see
+@code{--authorize} below.)
+
+@item --missing
+Read a list of store file names from the standard input, one per line, and
+write on the standard output the subset of these files missing from the
+store.
+
+@item --generate-key[=@var{parameters}]
+@cindex signing, archives
+Generate a new key pair for the daemon.  This is a prerequisite before
+archives can be exported with @code{--export}.  Note that this operation
+usually takes time, because it needs to gather enough entropy to generate
+the key pair.
+
+The generated key pair is typically stored under @file{/etc/guix}, in
+@file{signing-key.pub} (public key) and @file{signing-key.sec} (private key,
+which must be kept secret.)  When @var{parameters} is omitted, an ECDSA key
+using the Ed25519 curve is generated, or, for Libgcrypt versions before
+1.6.0, it is a 4096-bit RSA key.  Alternatively, @var{parameters} can
+specify @code{genkey} parameters suitable for Libgcrypt (@pxref{General
+public-key related Functions, @code{gcry_pk_genkey},, gcrypt, The Libgcrypt
+Reference Manual}).
+
+@item --authorize
+@cindex authorizing, archives
+Authorize imports signed by the public key passed on standard input.  The
+public key must be in ``s-expression advanced format''---i.e., the same
+format as the @file{signing-key.pub} file.
+
+The list of authorized keys is kept in the human-editable file
+@file{/etc/guix/acl}.  The file contains
+@url{http://people.csail.mit.edu/rivest/Sexp.txt, ``advanced-format
+s-expressions''} and is structured as an access-control list in the
+@url{http://theworld.com/~cme/spki.txt, Simple Public-Key Infrastructure
+(SPKI)}.
+
+@item --extract=@var{directory}
+@itemx -x @var{directory}
+Read a single-item archive as served by substitute servers
+(@pxref{Substitute}) and extract it to @var{directory}.  This is a
+low-level operation needed in only very narrow use cases; see below.
+
+For example, the following command extracts the substitute for Emacs served
+by @code{hydra.gnu.org} to @file{/tmp/emacs}:
+
+@example
+$ wget -O - \
+  https://hydra.gnu.org/nar/@dots{}-emacs-24.5 \
+  | bunzip2 | guix archive -x /tmp/emacs
+@end example
+
+Single-item archives are different from multiple-item archives produced by
+@command{guix archive --export}; they contain a single store item, and they
+do @emph{not} embed a signature.  Thus this operation does @emph{no}
+signature verification and its output should be considered unsafe.
+
+The primary purpose of this operation is to facilitate inspection of archive
+contents coming from possibly untrusted substitute servers.

+@chapter Programmierschnittstelle
+
+GNU Guix provides several Scheme programming interfaces (APIs) to define,
+build, and query packages.  The first interface allows users to write
+high-level package definitions.  These definitions refer to familiar
+packaging concepts, such as the name and version of a package, its build
+system, and its dependencies.  These definitions can then be turned into
+concrete build actions.
+
+Build actions are performed by the Guix daemon, on behalf of users.  In a
+standard setup, the daemon has write access to the store---the
+@file{/gnu/store} directory---whereas users do not.  The recommended setup
+also has the daemon perform builds in chroots, under a specific build users,
+to minimize interference with the rest of the system.
+
+@cindex Ableitung
+Lower-level APIs are available to interact with the daemon and the store.
+To instruct the daemon to perform a build action, users actually provide it
+with a @dfn{derivation}.  A derivation is a low-level representation of the
+build actions to be taken, and the environment in which they should
+occur---derivations are to package definitions what assembly is to C
+programs.  The term ``derivation'' comes from the fact that build results
+@emph{derive} from them.
+
+This chapter describes all these APIs in turn, starting from high-level
+package definitions.

+@section Pakete definieren
+
+The high-level interface to package definitions is implemented in the
+@code{(guix packages)} and @code{(guix build-system)} modules.  As an
+example, the package definition, or @dfn{recipe}, for the GNU Hello package
+looks like this:
+
+@example
+(define-module (gnu packages hello)
+  #:use-module (guix packages)
+  #:use-module (guix download)
+  #:use-module (guix build-system gnu)
+  #:use-module (guix licenses)
+  #:use-module (gnu packages gawk))
+
+(define-public hello
+  (package
+    (name "hello")
+    (version "2.10")
+    (source (origin
+              (method url-fetch)
+              (uri (string-append "mirror://gnu/hello/hello-" version
+                                  ".tar.gz"))
+              (sha256
+               (base32
+                "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"))))
+    (build-system gnu-build-system)
+    (arguments '(#:configure-flags '("--enable-silent-rules")))
+    (inputs `(("gawk" ,gawk)))
+    (synopsis "Hello, GNU world: An example GNU package")
+    (description "Guess what GNU Hello prints!")
+    (home-page "http://www.gnu.org/software/hello/")
+    (license gpl3+)))
+@end example
+
+@noindent
+Without being a Scheme expert, the reader may have guessed the meaning of
+the various fields here.  This expression binds the variable @code{hello} to
+a @code{<package>} object, which is essentially a record (@pxref{SRFI-9,
+Scheme records,, guile, GNU Guile Reference Manual}).  This package object
+can be inspected using procedures found in the @code{(guix packages)}
+module; for instance, @code{(package-name hello)}
+returns---surprise!---@code{"hello"}.
+
+With luck, you may be able to import part or all of the definition of the
+package you are interested in from another repository, using the @code{guix
+import} command (@pxref{Aufruf von guix import}).
+
+In the example above, @var{hello} is defined in a module of its own,
+@code{(gnu packages hello)}.  Technically, this is not strictly necessary,
+but it is convenient to do so: all the packages defined in modules under
+@code{(gnu packages @dots{})} are automatically known to the command-line
+tools (@pxref{Paketmodule}).
+
+There are a few points worth noting in the above package definition:
+
+@itemize
+@item
+The @code{source} field of the package is an @code{<origin>} object
+(@pxref{„origin“-Referenz}, for the complete reference).  Here, the
+@code{url-fetch} method from @code{(guix download)} is used, meaning that
+the source is a file to be downloaded over FTP or HTTP.
+
+The @code{mirror://gnu} prefix instructs @code{url-fetch} to use one of the
+GNU mirrors defined in @code{(guix download)}.
+
+The @code{sha256} field specifies the expected SHA256 hash of the file being
+downloaded.  It is mandatory, and allows Guix to check the integrity of the
+file.  The @code{(base32 @dots{})} form introduces the base32 representation
+of the hash.  You can obtain this information with @code{guix download}
+(@pxref{Aufruf von guix download}) and @code{guix hash} (@pxref{Aufruf von guix hash}).
+
+@cindex patches
+When needed, the @code{origin} form can also have a @code{patches} field
+listing patches to be applied, and a @code{snippet} field giving a Scheme
+expression to modify the source code.
+
+@item
+@cindex GNU-Erstellungssystem
+The @code{build-system} field specifies the procedure to build the package
+(@pxref{Erstellungssysteme}).  Here, @var{gnu-build-system} represents the
+familiar GNU Build System, where packages may be configured, built, and
+installed with the usual @code{./configure && make && make check && make
+install} command sequence.
+
+@item
+The @code{arguments} field specifies options for the build system
+(@pxref{Erstellungssysteme}).  Here it is interpreted by @var{gnu-build-system}
+as a request run @file{configure} with the @code{--enable-silent-rules}
+flag.
+
+@cindex quote
+@cindex quoting
+@findex '
+@findex quote
+What about these quote (@code{'}) characters? They are Scheme syntax to
+introduce a literal list; @code{'} is synonymous with @code{quote}.
+@xref{Expression Syntax, quoting,, guile, GNU Guile Reference Manual}, for
+details.  Here the value of the @code{arguments} field is a list of
+arguments passed to the build system down the road, as with @code{apply}
+(@pxref{Fly Evaluation, @code{apply},, guile, GNU Guile Reference Manual}).
+
+The hash-colon (@code{#:}) sequence defines a Scheme @dfn{keyword}
+(@pxref{Keywords,,, guile, GNU Guile Reference Manual}), and
+@code{#:configure-flags} is a keyword used to pass a keyword argument to the
+build system (@pxref{Coding With Keywords,,, guile, GNU Guile Reference
+Manual}).
+
+@item
+The @code{inputs} field specifies inputs to the build process---i.e.,
+build-time or run-time dependencies of the package.  Here, we define an
+input called @code{"gawk"} whose value is that of the @var{gawk} variable;
+@var{gawk} is itself bound to a @code{<package>} object.
+
+@cindex backquote (quasiquote)
+@findex `
+@findex quasiquote
+@cindex comma (unquote)
+@findex ,
+@findex unquote
+@findex ,@@
+@findex unquote-splicing
+Again, @code{`} (a backquote, synonymous with @code{quasiquote}) allows us
+to introduce a literal list in the @code{inputs} field, while @code{,} (a
+comma, synonymous with @code{unquote}) allows us to insert a value in that
+list (@pxref{Expression Syntax, unquote,, guile, GNU Guile Reference
+Manual}).
+
+Note that GCC, Coreutils, Bash, and other essential tools do not need to be
+specified as inputs here.  Instead, @var{gnu-build-system} takes care of
+ensuring that they are present (@pxref{Erstellungssysteme}).
+
+However, any other dependencies need to be specified in the @code{inputs}
+field.  Any dependency not specified here will simply be unavailable to the
+build process, possibly leading to a build failure.
+@end itemize
+
+@xref{„package“-Referenz}, for a full description of possible fields.
+
+Once a package definition is in place, the package may actually be built
+using the @code{guix build} command-line tool (@pxref{Aufruf von guix build}),
+troubleshooting any build failures you encounter (@pxref{Fehlschläge beim Erstellen untersuchen}).  You can easily jump back to the package definition using the
+@command{guix edit} command (@pxref{Aufruf von guix edit}).  @xref{Paketrichtlinien}, for more information on how to test package definitions, and
+@ref{Aufruf von guix lint}, for information on how to check a definition for
+style conformance.
+@vindex GUIX_PACKAGE_PATH
+Lastly, @pxref{Channels}, for information on how to extend the distribution
+by adding your own package definitions in a ``channel''.
+
+Finally, updating the package definition to a new upstream version can be
+partly automated by the @command{guix refresh} command (@pxref{Aufruf von guix refresh}).
+
+Behind the scenes, a derivation corresponding to the @code{<package>} object
+is first computed by the @code{package-derivation} procedure.  That
+derivation is stored in a @code{.drv} file under @file{/gnu/store}.  The
+build actions it prescribes may then be realized by using the
+@code{build-derivations} procedure (@pxref{Der Store}).
+
+@deffn {Scheme Procedure} package-derivation @var{store} @var{package} [@var{system}]
+Return the @code{<derivation>} object of @var{package} for @var{system}
+(@pxref{Ableitungen}).
+
+@var{package} must be a valid @code{<package>} object, and @var{system} must
+be a string denoting the target system type---e.g., @code{"x86_64-linux"}
+for an x86_64 Linux-based GNU system.  @var{store} must be a connection to
+the daemon, which operates on the store (@pxref{Der Store}).
+@end deffn
+
+@noindent
+@cindex cross-compilation
+Similarly, it is possible to compute a derivation that cross-builds a
+package for some other system:
+
+@deffn {Scheme Procedure} package-cross-derivation @var{store} @
+            @var{package} @var{target} [@var{system}] Return the @code{<derivation>}
+object of @var{package} cross-built from @var{system} to @var{target}.
+
+@var{target} must be a valid GNU triplet denoting the target hardware and
+operating system, such as @code{"mips64el-linux-gnu"} (@pxref{Configuration
+Names, GNU configuration triplets,, configure, GNU Configure and Build
+System}).
+@end deffn
+
+@cindex package transformations
+@cindex input rewriting
+@cindex dependency tree rewriting
+Packages can be manipulated in arbitrary ways.  An example of a useful
+transformation is @dfn{input rewriting}, whereby the dependency tree of a
+package is rewritten by replacing specific inputs by others:
+
+@deffn {Scheme Procedure} package-input-rewriting @var{replacements} @
+           [@var{rewrite-name}] Return a procedure that, when passed a package,
+replaces its direct and indirect dependencies (but not its implicit inputs)
+according to @var{replacements}.  @var{replacements} is a list of package
+pairs; the first element of each pair is the package to replace, and the
+second one is the replacement.
+
+Optionally, @var{rewrite-name} is a one-argument procedure that takes the
+name of a package and returns its new name after rewrite.
+@end deffn
+
+@noindent
+Consider this example:
+
+@example
+(define libressl-instead-of-openssl
+  ;; This is a procedure to replace OPENSSL by LIBRESSL,
+  ;; recursively.
+  (package-input-rewriting `((,openssl . ,libressl))))
+
+(define git-with-libressl
+  (libressl-instead-of-openssl git))
+@end example
+
+@noindent
+Here we first define a rewriting procedure that replaces @var{openssl} with
+@var{libressl}.  Then we use it to define a @dfn{variant} of the @var{git}
+package that uses @var{libressl} instead of @var{openssl}.  This is exactly
+what the @option{--with-input} command-line option does (@pxref{Paketumwandlungsoptionen, @option{--with-input}}).
+
+A more generic procedure to rewrite a package dependency graph is
+@code{package-mapping}: it supports arbitrary changes to nodes in the graph.
+
+@deffn {Scheme Procedure} package-mapping @var{proc} [@var{cut?}]
+Return a procedure that, given a package, applies @var{proc} to all the
+packages depended on and returns the resulting package.  The procedure stops
+recursion when @var{cut?} returns true for a given package.

+on package outputs).  For example, the list below specifies three inputs:
+
+@example
+`(("libffi" ,libffi)
+  ("libunistring" ,libunistring)
+  ("glib:bin" ,glib "bin"))  ;the "bin" output of Glib
+@end example
+
+@cindex cross compilation, package dependencies
+The distinction between @code{native-inputs} and @code{inputs} is necessary
+when considering cross-compilation.  When cross-compiling, dependencies
+listed in @code{inputs} are built for the @emph{target} architecture;
+conversely, dependencies listed in @code{native-inputs} are built for the
+architecture of the @emph{build} machine.
+
+@code{native-inputs} is typically used to list tools needed at build time,
+but not at run time, such as Autoconf, Automake, pkg-config, Gettext, or
+Bison.  @command{guix lint} can report likely mistakes in this area
+(@pxref{Aufruf von guix lint}).
+
+@anchor{package-propagated-inputs}
+Lastly, @code{propagated-inputs} is similar to @code{inputs}, but the
+specified packages will be automatically installed alongside the package
+they belong to (@pxref{package-cmd-propagated-inputs, @command{guix
+package}}, for information on how @command{guix package} deals with
+propagated inputs.)
+
+For example this is necessary when a C/C++ library needs headers of another
+library to compile, or when a pkg-config file refers to another one @i{via}
+its @code{Requires} field.
+
+Another example where @code{propagated-inputs} is useful is for languages
+that lack a facility to record the run-time search path akin to the
+@code{RUNPATH} of ELF files; this includes Guile, Python, Perl, and more.
+To ensure that libraries written in those languages can find library code
+they depend on at run time, run-time dependencies must be listed in
+@code{propagated-inputs} rather than @code{inputs}.
+
+@item @code{self-native-input?} (default: @code{#f})
+This is a Boolean field telling whether the package should use itself as a
+native input when cross-compiling.
+
+@item @code{outputs} (default: @code{'("out")})
+The list of output names of the package.  @xref{Pakete mit mehreren Ausgaben.}, for typical uses of additional outputs.
+
+@item @code{native-search-paths} (default: @code{'()})
+@itemx @code{search-paths} (default: @code{'()})
+A list of @code{search-path-specification} objects describing search-path
+environment variables honored by the package.
+
+@item @code{replacement} (default: @code{#f})
+This must be either @code{#f} or a package object that will be used as a
+@dfn{replacement} for this package.  @xref{Sicherheitsaktualisierungen, grafts}, for
+details.
+
+@item @code{synopsis}
+Eine einzeilige Beschreibung des Pakets.
+
+@item @code{description}
+Eine ausführlichere Beschreibung des Pakets.
+
+@item @code{license}
+@cindex license, of packages
+The license of the package; a value from @code{(guix licenses)}, or a list
+of such values.
+
+@item @code{home-page}
+The URL to the home-page of the package, as a string.
+
+@item @code{supported-systems} (default: @var{%supported-systems})
+The list of systems supported by the package, as strings of the form
+@code{architecture-kernel}, for example @code{"x86_64-linux"}.
+
+@item @code{maintainers} (default: @code{'()})
+The list of maintainers of the package, as @code{maintainer} objects.
+
+@item @code{location} (default: source location of the @code{package} form)
+The source location of the package.  It is useful to override this when
+inheriting from another package, in which case this field is not
+automatically corrected.

+
+@deftp {Data Type} origin
+This is the data type representing a source code origin.
+

+@item @code{uri}
+An object containing the URI of the source.  The object type depends on the
+@code{method} (see below).  For example, when using the @var{url-fetch}

+represented as a string, or a list thereof.
+

+@item @var{git-fetch} from @code{(guix git-download)}
+clone the Git version control repository, and check out the revision
+specified in the @code{uri} field as a @code{git-reference} object; a
+@code{git-reference} looks like this:

+The file name under which the source code should be saved.  When this is

+
+@cindex build system
+Each package definition specifies a @dfn{build system} and arguments for
+that build system (@pxref{Pakete definieren}).  This @code{build-system}
+field represents the build procedure of the package, as well as implicit
+dependencies of that build procedure.
+
+Build systems are @code{<build-system>} objects.  The interface to create
+and manipulate them is provided by the @code{(guix build-system)} module,
+and actual build systems are exported by specific modules.
+
+@cindex bag (low-level package representation)
+Under the hood, build systems first compile package objects to @dfn{bags}.
+A @dfn{bag} is like a package, but with less ornamentation---in other words,
+a bag is a lower-level representation of a package, which includes all the
+inputs of that package, including some that were implicitly added by the
+build system.  This intermediate representation is then compiled to a
+derivation (@pxref{Ableitungen}).
+
+Build systems accept an optional list of @dfn{arguments}.  In package
+definitions, these are passed @i{via} the @code{arguments} field
+(@pxref{Pakete definieren}).  They are typically keyword arguments
+(@pxref{Optional Arguments, keyword arguments in Guile,, guile, GNU Guile
+Reference Manual}).  The value of these arguments is usually evaluated in
+the @dfn{build stratum}---i.e., by a Guile process launched by the daemon
+(@pxref{Ableitungen}).
+
+The main build system is @var{gnu-build-system}, which implements the
+standard build procedure for GNU and many other packages.  It is provided by
+the @code{(guix build-system gnu)} module.
+
+@defvr {Scheme Variable} gnu-build-system
+@var{gnu-build-system} represents the GNU Build System, and variants thereof
+(@pxref{Configuration, configuration and makefile conventions,, standards,
+GNU Coding Standards}).
+
+@cindex build phases
+In a nutshell, packages using it are configured, built, and installed with
+the usual @code{./configure && make && make check && make install} command
+sequence.  In practice, a few additional steps are often needed.  All these
+steps are split up in separate @dfn{phases}, notably@footnote{Please see the
+@code{(guix build gnu-build-system)} modules for more details about the
+build phases.}:
+
+@table @code
+@item unpack
+Unpack the source tarball, and change the current directory to the extracted
+source tree.  If the source is actually a directory, copy it to the build
+tree, and enter that directory.
+
+@item patch-source-shebangs
+Patch shebangs encountered in source files so they refer to the right store
+file names.  For instance, this changes @code{#!/bin/sh} to
+@code{#!/gnu/store/@dots{}-bash-4.3/bin/sh}.
+
+@item configure
+Run the @file{configure} script with a number of default options, such as
+@code{--prefix=/gnu/store/@dots{}}, as well as the options specified by the
+@code{#:configure-flags} argument.
+
+@item build
+Run @code{make} with the list of flags specified with @code{#:make-flags}.
+If the @code{#:parallel-build?} argument is true (the default), build with
+@code{make -j}.
+
+@item check
+Run @code{make check}, or some other target specified with
+@code{#:test-target}, unless @code{#:tests? #f} is passed.  If the
+@code{#:parallel-tests?} argument is true (the default), run @code{make
+check -j}.
+
+@item install
+Run @code{make install} with the flags listed in @code{#:make-flags}.
+
+@item patch-shebangs
+Patch shebangs on the installed executable files.
+
+@item strip
+Strip debugging symbols from ELF files (unless @code{#:strip-binaries?} is
+false), copying them to the @code{debug} output when available
+(@pxref{Dateien zur Fehlersuche installieren}).
+@end table
+
+@vindex %standard-phases
+The build-side module @code{(guix build gnu-build-system)} defines
+@var{%standard-phases} as the default list of build phases.
+@var{%standard-phases} is a list of symbol/procedure pairs, where the
+procedure implements the actual phase.
+
+The list of phases used for a particular package can be changed with the
+@code{#:phases} parameter.  For instance, passing:
+
+@example
+#:phases (modify-phases %standard-phases (delete 'configure))
+@end example
+
+means that all the phases described above will be used, except the
+@code{configure} phase.
+
+In addition, this build system ensures that the ``standard'' environment for
+GNU packages is available.  This includes tools such as GCC, libc,
+Coreutils, Bash, Make, Diffutils, grep, and sed (see the @code{(guix
+build-system gnu)} module for a complete list).  We call these the
+@dfn{implicit inputs} of a package, because package definitions do not have
+to mention them.
+@end defvr
+
+Other @code{<build-system>} objects are defined to support other conventions
+and tools used by free software packages.  They inherit most of
+@var{gnu-build-system}, and differ mainly in the set of inputs implicitly
+added to the build process, and in the list of phases executed.  Some of
+these build systems are listed below.
+
+@defvr {Scheme Variable} ant-build-system
+This variable is exported by @code{(guix build-system ant)}.  It implements
+the build procedure for Java packages that can be built with
+@url{http://ant.apache.org/, Ant build tool}.
+
+It adds both @code{ant} and the @dfn{Java Development Kit} (JDK) as provided
+by the @code{icedtea} package to the set of inputs.  Different packages can
+be specified with the @code{#:ant} and @code{#:jdk} parameters,
+respectively.
+
+When the original package does not provide a suitable Ant build file, the
+parameter @code{#:jar-name} can be used to generate a minimal Ant build file
+@file{build.xml} with tasks to build the specified jar archive.  In this
+case the parameter @code{#:source-dir} can be used to specify the source
+sub-directory, defaulting to ``src''.
+
+The @code{#:main-class} parameter can be used with the minimal ant buildfile
+to specify the main class of the resulting jar.  This makes the jar file
+executable.  The @code{#:test-include} parameter can be used to specify the
+list of junit tests to run. It defaults to @code{(list "**/*Test.java")}.
+The @code{#:test-exclude} can be used to disable some tests. It defaults to
+@code{(list "**/Abstract*.java")}, because abstract classes cannot be run as
+tests.
+
+The parameter @code{#:build-target} can be used to specify the Ant task that
+should be run during the @code{build} phase.  By default the ``jar'' task
+will be run.
+
+@end defvr
+
+@defvr {Scheme Variable} android-ndk-build-system
+@cindex Android distribution
+@cindex Android NDK build system
+This variable is exported by @code{(guix build-system android-ndk)}.  It
+implements a build procedure for Android NDK (native development kit)
+packages using a Guix-specific build process.
+
+The build system assumes that packages install their public interface
+(header) files to the subdirectory "include" of the "out" output and their
+libraries to the subdirectory "lib" of the "out" output.
+
+It's also assumed that the union of all the dependencies of a package has no
+conflicting files.
+
+For the time being, cross-compilation is not supported - so right now the
+libraries and header files are assumed to be host tools.
+
+@end defvr
+
+@defvr {Scheme Variable} asdf-build-system/source
+@defvrx {Scheme Variable} asdf-build-system/sbcl
+@defvrx {Scheme Variable} asdf-build-system/ecl
+
+These variables, exported by @code{(guix build-system asdf)}, implement
+build procedures for Common Lisp packages using
+@url{https://common-lisp.net/project/asdf/, ``ASDF''}. ASDF is a system
+definition facility for Common Lisp programs and libraries.
+
+The @code{asdf-build-system/source} system installs the packages in source
+form, and can be loaded using any common lisp implementation, via ASDF.  The
+others, such as @code{asdf-build-system/sbcl}, install binary systems in the
+format which a particular implementation understands.  These build systems
+can also be used to produce executable programs, or lisp images which
+contain a set of packages pre-loaded.
+
+The build system uses naming conventions.  For binary packages, the package
+name should be prefixed with the lisp implementation, such as @code{sbcl-}
+for @code{asdf-build-system/sbcl}.
+
+Additionally, the corresponding source package should be labeled using the
+same convention as python packages (see @ref{Python-Module}), using the
+@code{cl-} prefix.
+
+For binary packages, each system should be defined as a Guix package.  If
+one package @code{origin} contains several systems, package variants can be
+created in order to build all the systems.  Source packages, which use
+@code{asdf-build-system/source}, may contain several systems.
+
+In order to create executable programs and images, the build-side procedures
+@code{build-program} and @code{build-image} can be used.  They should be
+called in a build phase after the @code{create-symlinks} phase, so that the
+system which was just built can be used within the resulting image.
+@code{build-program} requires a list of Common Lisp expressions to be passed
+as the @code{#:entry-program} argument.
+
+If the system is not defined within its own @code{.asd} file of the same
+name, then the @code{#:asd-file} parameter should be used to specify which
+file the system is defined in.  Furthermore, if the package defines a system
+for its tests in a separate file, it will be loaded before the tests are run
+if it is specified by the @code{#:test-asd-file} parameter.  If it is not
+set, the files @code{<system>-tests.asd}, @code{<system>-test.asd},
+@code{tests.asd}, and @code{test.asd} will be tried if they exist.
+
+If for some reason the package must be named in a different way than the
+naming conventions suggest, the @code{#:asd-system-name} parameter can be
+used to specify the name of the system.
+
+@end defvr
+
+@defvr {Scheme Variable} cargo-build-system
+@cindex Rust programming language
+@cindex Cargo (Rust build system)
+This variable is exported by @code{(guix build-system cargo)}.  It supports
+builds of packages using Cargo, the build tool of the
+@uref{https://www.rust-lang.org, Rust programming language}.
+
+In its @code{configure} phase, this build system replaces dependencies
+specified in the @file{Carto.toml} file with inputs to the Guix package.
+The @code{install} phase installs the binaries, and it also installs the
+source code and @file{Cargo.toml} file.
+@end defvr
+
+@cindex Clojure (programming language)
+@cindex simple Clojure build system
+@defvr {Scheme Variable} clojure-build-system
+This variable is exported by @code{(guix build-system clojure)}.  It
+implements a simple build procedure for @uref{https://clojure.org/, Clojure}
+packages using plain old @code{compile} in Clojure.  Cross-compilation is
+not supported yet.
+
+It adds @code{clojure}, @code{icedtea} and @code{zip} to the set of inputs.
+Different packages can be specified with the @code{#:clojure}, @code{#:jdk}
+and @code{#:zip} parameters, respectively.
+
+A list of source directories, test directories and jar names can be
+specified with the @code{#:source-dirs}, @code{#:test-dirs} and
+@code{#:jar-names} parameters, respectively.  Compile directory and main
+class can be specified with the @code{#:compile-dir} and @code{#:main-class}
+parameters, respectively.  Other parameters are documented below.
+
+This build system is an extension of @var{ant-build-system}, but with the
+following phases changed:
+
+@table @code
+
+@item build
+This phase calls @code{compile} in Clojure to compile source files and runs
+@command{jar} to create jars from both source files and compiled files
+according to the include list and exclude list specified in
+@code{#:aot-include} and @code{#:aot-exclude}, respectively.  The exclude
+list has priority over the include list.  These lists consist of symbols
+representing Clojure libraries or the special keyword @code{#:all}
+representing all Clojure libraries found under the source directories.  The
+parameter @code{#:omit-source?} decides if source should be included into
+the jars.
+
+@item check
+This phase runs tests according to the include list and exclude list
+specified in @code{#:test-include} and @code{#:test-exclude}, respectively.
+Their meanings are analogous to that of @code{#:aot-include} and
+@code{#:aot-exclude}, except that the special keyword @code{#:all} now
+stands for all Clojure libraries found under the test directories.  The
+parameter @code{#:tests?} decides if tests should be run.
+
+@item install
+This phase installs all jars built previously.
+@end table
+
+Apart from the above, this build system also contains an additional phase:
+
+@table @code
+
+@item install-doc
+This phase installs all top-level files with base name matching
+@var{%doc-regex}.  A different regex can be specified with the
+@code{#:doc-regex} parameter.  All files (recursively) inside the
+documentation directories specified in @code{#:doc-dirs} are installed as
+well.
+@end table
+@end defvr
+
+@defvr {Scheme Variable} cmake-build-system
+This variable is exported by @code{(guix build-system cmake)}.  It
+implements the build procedure for packages using the
+@url{http://www.cmake.org, CMake build tool}.
+
+It automatically adds the @code{cmake} package to the set of inputs.  Which
+package is used can be specified with the @code{#:cmake} parameter.
+
+The @code{#:configure-flags} parameter is taken as a list of flags passed to
+the @command{cmake} command.  The @code{#:build-type} parameter specifies in
+abstract terms the flags passed to the compiler; it defaults to
+@code{"RelWithDebInfo"} (short for ``release mode with debugging
+information''), which roughly means that code is compiled with @code{-O2
+-g}, as is the case for Autoconf-based packages by default.
+@end defvr
+
+@defvr {Scheme Variable} go-build-system
+This variable is exported by @code{(guix build-system go)}.  It implements a
+build procedure for Go packages using the standard
+@url{https://golang.org/cmd/go/#hdr-Compile_packages_and_dependencies, Go
+build mechanisms}.
+
+The user is expected to provide a value for the key @code{#:import-path}
+and, in some cases, @code{#:unpack-path}.  The
+@url{https://golang.org/doc/code.html#ImportPaths, import path} corresponds
+to the file system path expected by the package's build scripts and any
+referring packages, and provides a unique way to refer to a Go package.  It
+is typically based on a combination of the package source code's remote URI
+and file system hierarchy structure.  In some cases, you will need to unpack
+the package's source code to a different directory structure than the one
+indicated by the import path, and @code{#:unpack-path} should be used in
+such cases.
+
+Packages that provide Go libraries should be installed along with their
+source code.  The key @code{#:install-source?}, which defaults to @code{#t},
+controls whether or not the source code is installed.  It can be set to
+@code{#f} for packages that only provide executable files.
+@end defvr
+
+@defvr {Scheme Variable} glib-or-gtk-build-system
+This variable is exported by @code{(guix build-system glib-or-gtk)}.  It is
+intended for use with packages making use of GLib or GTK+.
+
+This build system adds the following two phases to the ones defined by
+@var{gnu-build-system}:
+
+@table @code
+@item glib-or-gtk-wrap
+The phase @code{glib-or-gtk-wrap} ensures that programs in @file{bin/} are
+able to find GLib ``schemas'' and
+@uref{https://developer.gnome.org/gtk3/stable/gtk-running.html, GTK+
+modules}.  This is achieved by wrapping the programs in launch scripts that
+appropriately set the @code{XDG_DATA_DIRS} and @code{GTK_PATH} environment
+variables.
+
+It is possible to exclude specific package outputs from that wrapping
+process by listing their names in the
+@code{#:glib-or-gtk-wrap-excluded-outputs} parameter.  This is useful when
+an output is known not to contain any GLib or GTK+ binaries, and where
+wrapping would gratuitously add a dependency of that output on GLib and
+GTK+.
+
+@item glib-or-gtk-compile-schemas
+The phase @code{glib-or-gtk-compile-schemas} makes sure that all
+@uref{https://developer.gnome.org/gio/stable/glib-compile-schemas.html,
+GSettings schemas} of GLib are compiled.  Compilation is performed by the
+@command{glib-compile-schemas} program.  It is provided by the package
+@code{glib:bin} which is automatically imported by the build system.  The
+@code{glib} package providing @command{glib-compile-schemas} can be
+specified with the @code{#:glib} parameter.
+@end table
+
+Both phases are executed after the @code{install} phase.
+@end defvr
+
+@defvr {Scheme Variable} guile-build-system
+This build system is for Guile packages that consist exclusively of Scheme
+code and that are so lean that they don't even have a makefile, let alone a
+@file{configure} script.  It compiles Scheme code using @command{guild
+compile} (@pxref{Compilation,,, guile, GNU Guile Reference Manual}) and
+installs the @file{.scm} and @file{.go} files in the right place.  It also
+installs documentation.
+
+This build system supports cross-compilation by using the @code{--target}
+option of @command{guild compile}.
+
+Packages built with @code{guile-build-system} must provide a Guile package
+in their @code{native-inputs} field.
+@end defvr
+
+@defvr {Scheme Variable} minify-build-system
+This variable is exported by @code{(guix build-system minify)}.  It
+implements a minification procedure for simple JavaScript packages.
+
+It adds @code{uglify-js} to the set of inputs and uses it to compress all
+JavaScript files in the @file{src} directory.  A different minifier package
+can be specified with the @code{#:uglify-js} parameter, but it is expected
+that the package writes the minified code to the standard output.
+
+When the input JavaScript files are not all located in the @file{src}
+directory, the parameter @code{#:javascript-files} can be used to specify a
+list of file names to feed to the minifier.
+@end defvr
+
+@defvr {Scheme Variable} ocaml-build-system
+This variable is exported by @code{(guix build-system ocaml)}.  It
+implements a build procedure for @uref{https://ocaml.org, OCaml} packages,
+which consists of choosing the correct set of commands to run for each
+package.  OCaml packages can expect many different commands to be run.  This
+build system will try some of them.
+
+When the package has a @file{setup.ml} file present at the top-level, it
+will run @code{ocaml setup.ml -configure}, @code{ocaml setup.ml -build} and
+@code{ocaml setup.ml -install}.  The build system will assume that this file
+was generated by @uref{http://oasis.forge.ocamlcore.org/, OASIS} and will
+take care of setting the prefix and enabling tests if they are not
+disabled.  You can pass configure and build flags with the
+@code{#:configure-flags} and @code{#:build-flags}.  The @code{#:test-flags}
+key can be passed to change the set of flags used to enable tests.  The
+@code{#:use-make?} key can be used to bypass this system in the build and
+install phases.
+
+When the package has a @file{configure} file, it is assumed that it is a
+hand-made configure script that requires a different argument format than in
+the @code{gnu-build-system}.  You can add more flags with the
+@code{#:configure-flags} key.
+
+When the package has a @file{Makefile} file (or @code{#:use-make?} is
+@code{#t}), it will be used and more flags can be passed to the build and
+install phases with the @code{#:make-flags} key.
+
+Finally, some packages do not have these files and use a somewhat standard
+location for its build system.  In that case, the build system will run
+@code{ocaml pkg/pkg.ml} or @code{ocaml pkg/build.ml} and take care of
+providing the path to the required findlib module.  Additional flags can be
+passed via the @code{#:build-flags} key.  Install is taken care of by
+@command{opam-installer}.  In this case, the @code{opam} package must be
+added to the @code{native-inputs} field of the package definition.
+
+Note that most OCaml packages assume they will be installed in the same
+directory as OCaml, which is not what we want in guix.  In particular, they
+will install @file{.so} files in their module's directory, which is usually
+fine because it is in the OCaml compiler directory.  In guix though, these
+libraries cannot be found and we use @code{CAML_LD_LIBRARY_PATH}.  This
+variable points to @file{lib/ocaml/site-lib/stubslibs} and this is where
+@file{.so} libraries should be installed.

+@defvr {Scheme Variable} python-build-system
+This variable is exported by @code{(guix build-system python)}.  It
+implements the more or less standard build procedure used by Python
+packages, which consists in running @code{python setup.py build} and then
+@code{python setup.py install --prefix=/gnu/store/@dots{}}.
+
+For packages that install stand-alone Python programs under @code{bin/}, it
+takes care of wrapping these programs so that their @code{PYTHONPATH}
+environment variable points to all the Python libraries they depend on.
+
+Which Python package is used to perform the build can be specified with the
+@code{#:python} parameter.  This is a useful way to force a package to be
+built for a specific version of the Python interpreter, which might be
+necessary if the package is only compatible with a single interpreter
+version.
+
+By default guix calls @code{setup.py} under control of @code{setuptools},
+much like @command{pip} does.  Some packages are not compatible with
+setuptools (and pip), thus you can disable this by setting the
+@code{#:use-setuptools} parameter to @code{#f}.
+@end defvr
+
+@defvr {Scheme Variable} perl-build-system
+This variable is exported by @code{(guix build-system perl)}.  It implements
+the standard build procedure for Perl packages, which either consists in
+running @code{perl Build.PL --prefix=/gnu/store/@dots{}}, followed by
+@code{Build} and @code{Build install}; or in running @code{perl Makefile.PL
+PREFIX=/gnu/store/@dots{}}, followed by @code{make} and @code{make install},
+depending on which of @code{Build.PL} or @code{Makefile.PL} is present in
+the package distribution.  Preference is given to the former if both
+@code{Build.PL} and @code{Makefile.PL} exist in the package distribution.
+This preference can be reversed by specifying @code{#t} for the
+@code{#:make-maker?} parameter.
+
+The initial @code{perl Makefile.PL} or @code{perl Build.PL} invocation
+passes flags specified by the @code{#:make-maker-flags} or
+@code{#:module-build-flags} parameter, respectively.
+
+Which Perl package is used can be specified with @code{#:perl}.
+@end defvr
+
+@defvr {Scheme Variable} r-build-system
+This variable is exported by @code{(guix build-system r)}.  It implements
+the build procedure used by @uref{http://r-project.org, R} packages, which
+essentially is little more than running @code{R CMD INSTALL
+--library=/gnu/store/@dots{}} in an environment where @code{R_LIBS_SITE}
+contains the paths to all R package inputs.  Tests are run after
+installation using the R function @code{tools::testInstalledPackage}.
+@end defvr
+
+@defvr {Scheme Variable} texlive-build-system
+This variable is exported by @code{(guix build-system texlive)}.  It is used
+to build TeX packages in batch mode with a specified engine.  The build
+system sets the @code{TEXINPUTS} variable to find all TeX source files in
+the inputs.
+
+By default it runs @code{luatex} on all files ending on @code{ins}.  A
+different engine and format can be specified with the @code{#:tex-format}
+argument.  Different build targets can be specified with the
+@code{#:build-targets} argument, which expects a list of file names.  The
+build system adds only @code{texlive-bin} and @code{texlive-latex-base}
+(both from @code{(gnu packages tex}) to the inputs.  Both can be overridden
+with the arguments @code{#:texlive-bin} and @code{#:texlive-latex-base},
+respectively.
+
+The @code{#:tex-directory} parameter tells the build system where to install
+the built files under the texmf tree.
+@end defvr
+
+@defvr {Scheme Variable} ruby-build-system
+This variable is exported by @code{(guix build-system ruby)}.  It implements
+the RubyGems build procedure used by Ruby packages, which involves running
+@code{gem build} followed by @code{gem install}.
+
+The @code{source} field of a package that uses this build system typically
+references a gem archive, since this is the format that Ruby developers use
+when releasing their software.  The build system unpacks the gem archive,
+potentially patches the source, runs the test suite, repackages the gem, and
+installs it.  Additionally, directories and tarballs may be referenced to
+allow building unreleased gems from Git or a traditional source release
+tarball.
+
+Which Ruby package is used can be specified with the @code{#:ruby}
+parameter.  A list of additional flags to be passed to the @command{gem}
+command can be specified with the @code{#:gem-flags} parameter.
+@end defvr
+
+@defvr {Scheme Variable} waf-build-system
+This variable is exported by @code{(guix build-system waf)}.  It implements
+a build procedure around the @code{waf} script.  The common
+phases---@code{configure}, @code{build}, and @code{install}---are
+implemented by passing their names as arguments to the @code{waf} script.
+
+The @code{waf} script is executed by the Python interpreter.  Which Python
+package is used to run the script can be specified with the @code{#:python}
+parameter.
+@end defvr
+
+@defvr {Scheme Variable} scons-build-system
+This variable is exported by @code{(guix build-system scons)}.  It
+implements the build procedure used by the SCons software construction
+tool.  This build system runs @code{scons} to build the package, @code{scons
+test} to run tests, and then @code{scons install} to install the package.
+
+Additional flags to be passed to @code{scons} can be specified with the
+@code{#:scons-flags} parameter.  The version of Python used to run SCons can
+be specified by selecting the appropriate SCons package with the
+@code{#:scons} parameter.
+@end defvr
+
+@defvr {Scheme Variable} haskell-build-system
+This variable is exported by @code{(guix build-system haskell)}.  It
+implements the Cabal build procedure used by Haskell packages, which
+involves running @code{runhaskell Setup.hs configure
+--prefix=/gnu/store/@dots{}} and @code{runhaskell Setup.hs build}.  Instead
+of installing the package by running @code{runhaskell Setup.hs install}, to
+avoid trying to register libraries in the read-only compiler store
+directory, the build system uses @code{runhaskell Setup.hs copy}, followed
+by @code{runhaskell Setup.hs register}.  In addition, the build system
+generates the package documentation by running @code{runhaskell Setup.hs
+haddock}, unless @code{#:haddock? #f} is passed.  Optional Haddock
+parameters can be passed with the help of the @code{#:haddock-flags}
+parameter.  If the file @code{Setup.hs} is not found, the build system looks
+for @code{Setup.lhs} instead.
+
+Which Haskell compiler is used can be specified with the @code{#:haskell}
+parameter which defaults to @code{ghc}.
+@end defvr
+
+@defvr {Scheme Variable} dub-build-system
+This variable is exported by @code{(guix build-system dub)}.  It implements

+manually.
+
+Which D compiler is used can be specified with the @code{#:ldc} parameter
+which defaults to @code{ldc}.
+@end defvr
+
+@defvr {Scheme Variable} emacs-build-system
+This variable is exported by @code{(guix build-system emacs)}.  It
+implements an installation procedure similar to the packaging system of
+Emacs itself (@pxref{Packages,,, emacs, The GNU Emacs Manual}).
+
+It first creates the @code{@var{package}-autoloads.el} file, then it byte
+compiles all Emacs Lisp files.  Differently from the Emacs packaging system,
+the Info documentation files are moved to the standard documentation
+directory and the @file{dir} file is deleted.  Each package is installed in
+its own directory under @file{share/emacs/site-lisp/guix.d}.
+@end defvr
+
+@defvr {Scheme Variable} font-build-system
+This variable is exported by @code{(guix build-system font)}.  It implements

+copied into place.  It copies font files to standard locations in the output
+directory.
+@end defvr
+
+@defvr {Scheme Variable} meson-build-system
+This variable is exported by @code{(guix build-system meson)}.  It
+implements the build procedure for packages that use
+@url{http://mesonbuild.com, Meson} as their build system.
+
+It adds both Meson and @uref{https://ninja-build.org/, Ninja} to the set of
+inputs, and they can be changed with the parameters @code{#:meson} and
+@code{#:ninja} if needed.  The default Meson is @code{meson-for-build},
+which is special because it doesn't clear the @code{RUNPATH} of binaries and
+libraries when they are installed.
+
+This build system is an extension of @var{gnu-build-system}, but with the
+following phases changed to some specific for Meson:
+
+@table @code
+
+@item configure
+The phase runs @code{meson} with the flags specified in
+@code{#:configure-flags}.  The flag @code{--build-type} is always set to
+@code{plain} unless something else is specified in @code{#:build-type}.
+
+@item build
+The phase runs @code{ninja} to build the package in parallel by default, but
+this can be changed with @code{#:parallel-build?}.
+
+@item check
+The phase runs @code{ninja} with the target specified in
+@code{#:test-target}, which is @code{"test"} by default.
+
+@item install
+The phase runs @code{ninja install} and can not be changed.
+@end table
+
+Apart from that, the build system also adds the following phases:
+
+@table @code
+
+@item fix-runpath
+This phase ensures that all binaries can find the libraries they need.  It
+searches for required libraries in subdirectories of the package being
+built, and adds those to @code{RUNPATH} where needed.  It also removes
+references to libraries left over from the build phase by
+@code{meson-for-build}, such as test dependencies, that aren't actually
+required for the program to run.
+
+@item glib-or-gtk-wrap
+This phase is the phase provided by @code{glib-or-gtk-build-system}, and it
+is not enabled by default.  It can be enabled with @code{#:glib-or-gtk?}.
+
+@item glib-or-gtk-compile-schemas
+This phase is the phase provided by @code{glib-or-gtk-build-system}, and it
+is not enabled by default.  It can be enabled with @code{#:glib-or-gtk?}.
+@end table
+@end defvr
+
+Lastly, for packages that do not need anything as sophisticated, a
+``trivial'' build system is provided.  It is trivial in the sense that it
+provides basically no support: it does not pull any implicit inputs, and
+does not have a notion of build phases.
+
+@defvr {Scheme Variable} trivial-build-system
+This variable is exported by @code{(guix build-system trivial)}.
+
+This build system requires a @code{#:builder} argument.  This argument must

+@section Der Store
+
+@cindex Store
+@cindex store items
+@cindex store paths
+
+Conceptually, the @dfn{store} is the place where derivations that have been
+built successfully are stored---by default, @file{/gnu/store}.
+Sub-directories in the store are referred to as @dfn{store items} or
+sometimes @dfn{store paths}.  The store has an associated database that
+contains information such as the store paths referred to by each store path,
+and the list of @emph{valid} store items---results of successful builds.
+This database resides in @file{@var{localstatedir}/guix/db}, where
+@var{localstatedir} is the state directory specified @i{via}
+@option{--localstatedir} at configure time, usually @file{/var}.
+
+The store is @emph{always} accessed by the daemon on behalf of its clients
+(@pxref{Aufruf des guix-daemon}).  To manipulate the store, clients connect to
+the daemon over a Unix-domain socket, send requests to it, and read the
+result---these are remote procedure calls, or RPCs.
+
+@quotation Anmerkung
+Users must @emph{never} modify files under @file{/gnu/store} directly.  This
+would lead to inconsistencies and break the immutability assumptions of
+Guix's functional model (@pxref{Einführung}).

+to check the integrity of the store and attempt recovery from accidental
+modifications.
+@end quotation
+
+The @code{(guix store)} module provides procedures to connect to the daemon,
+and to perform RPCs.  These are described below.  By default,
+@code{open-connection}, and thus all the @command{guix} commands, connect to
+the local daemon or to the URI specified by the @code{GUIX_DAEMON_SOCKET}
+environment variable.
+
+@defvr {Environment Variable} GUIX_DAEMON_SOCKET
+When set, the value of this variable should be a file name or a URI
+designating the daemon endpoint.  When it is a file name, it denotes a
+Unix-domain socket to connect to.  In addition to file names, the supported
+URI schemes are:
+
+@table @code
+@item file
+@itemx unix
+These are for Unix-domain sockets.
+@code{file:///var/guix/daemon-socket/socket} is equivalent to
+@file{/var/guix/daemon-socket/socket}.
+
+@item guix
+@cindex Daemon, Fernzugriff
+@cindex Fernzugriff auf den Daemon
+@cindex Daemon, Einrichten auf Clustern
+@cindex Cluster, Einrichtung des Daemons
+These URIs denote connections over TCP/IP, without encryption nor
+authentication of the remote host.  The URI must specify the host name and
+optionally a port number (by default port 44146 is used):
+
+@example
+guix://master.guix.example.org:1234
+@end example
+
+This setup is suitable on local networks, such as clusters, where only
+trusted nodes may connect to the build daemon at
+@code{master.guix.example.org}.
+
+The @code{--listen} option of @command{guix-daemon} can be used to instruct
+it to listen for TCP connections (@pxref{Aufruf des guix-daemon,
+@code{--listen}}).
+
+@item ssh
+@cindex SSH access to build daemons
+These URIs allow you to connect to a remote daemon over SSH@footnote{This

+look like this:
+
+@example
+ssh://charlie@@guix.example.org:22
+@end example
+
+As for @command{guix copy}, the usual OpenSSH client configuration files are
+honored (@pxref{Aufruf von guix copy}).

+@cindex derivations
+Low-level build actions and the environment in which they are performed are
+represented by @dfn{derivations}.  A derivation contains the following
+pieces of information:
+
+@itemize
+@item
+The outputs of the derivation---derivations produce at least one file or
+directory in the store, but may produce more.
+
+@item
+The inputs of the derivations, which may be other derivations or plain files
+in the store (patches, build scripts, etc.)
+
+@item
+The system type targeted by the derivation---e.g., @code{x86_64-linux}.
+
+@item
+The file name of a build script in the store, along with the arguments to be
+passed.
+
+@item
+A list of environment variables to be defined.
+
+@end itemize
+
+@cindex derivation path
+Derivations allow clients of the daemon to communicate build actions to the
+store.  They exist in two forms: as an in-memory representation, both on the
+client- and daemon-side, and as files in the store whose name end in
+@code{.drv}---these files are referred to as @dfn{derivation paths}.
+Derivations paths can be passed to the @code{build-derivations} procedure to
+perform the build actions they prescribe (@pxref{Der Store}).
+
+@cindex fixed-output derivations
+Operations such as file downloads and version-control checkouts for which
+the expected content hash is known in advance are modeled as
+@dfn{fixed-output derivations}.  Unlike regular derivations, the outputs of
+a fixed-output derivation are independent of its inputs---e.g., a source
+code download produces the same result regardless of the download method and
+tools being used.
+
+The @code{(guix derivations)} module provides a representation of
+derivations as Scheme objects, along with procedures to create and otherwise
+manipulate derivations.  The lowest-level primitive to create a derivation
+is the @code{derivation} procedure:
+
+@deffn {Scheme Procedure} derivation @var{store} @var{name} @var{builder} @
+  @var{args} [#:outputs '("out")] [#:hash #f] [#:hash-algo #f] @ [#:recursive?
+#f] [#:inputs '()] [#:env-vars '()] @ [#:system (%current-system)]
+[#:references-graphs #f] @ [#:allowed-references #f]
+[#:disallowed-references #f] @ [#:leaked-env-vars #f] [#:local-build? #f] @
+[#:substitutable? #t] [#:properties '()] Build a derivation with the given
+arguments, and return the resulting @code{<derivation>} object.
+
+When @var{hash} and @var{hash-algo} are given, a @dfn{fixed-output
+derivation} is created---i.e., one whose result is known in advance, such as
+a file download.  If, in addition, @var{recursive?} is true, then that fixed
+output may be an executable file or a directory and @var{hash} must be the
+hash of an archive containing this output.
+
+When @var{references-graphs} is true, it must be a list of file name/store
+path pairs.  In that case, the reference graph of each store path is
+exported in the build environment in the corresponding file, in a simple
+text format.
+
+When @var{allowed-references} is true, it must be a list of store items or
+outputs that the derivation's output may refer to.  Likewise,
+@var{disallowed-references}, if true, must be a list of things the outputs
+may @emph{not} refer to.
+
+When @var{leaked-env-vars} is true, it must be a list of strings denoting
+environment variables that are allowed to ``leak'' from the daemon's
+environment to the build environment.  This is only applicable to
+fixed-output derivations---i.e., when @var{hash} is true.  The main use is
+to allow variables such as @code{http_proxy} to be passed to derivations
+that download files.
+
+When @var{local-build?} is true, declare that the derivation is not a good
+candidate for offloading and should rather be built locally (@pxref{Auslagern des Daemons einrichten}).  This is the case for small derivations where the costs of
+data transfers would outweigh the benefits.
+
+When @var{substitutable?} is false, declare that substitutes of the
+derivation's output should not be used (@pxref{Substitute}).  This is
+useful, for instance, when building packages that capture details of the
+host CPU instruction set.
+
+@var{properties} must be an association list describing ``properties'' of
+the derivation.  It is kept as-is, uninterpreted, in the derivation.
+@end deffn
+
+@noindent
+Here's an example with a shell script as its builder, assuming @var{store}
+is an open connection to the daemon, and @var{bash} points to a Bash
+executable in the store:
+
+@lisp
+(use-modules (guix utils)
+             (guix store)
+             (guix derivations))
+
+(let ((builder   ; add the Bash script to the store
+        (add-text-to-store store "my-builder.sh"
+                           "echo hello world > $out\n" '())))
+  (derivation store "foo"
+              bash `("-e" ,builder)
+              #:inputs `((,bash) (,builder))
+              #:env-vars '(("HOME" . "/homeless"))))
+@result{} #<derivation /gnu/store/@dots{}-foo.drv => /gnu/store/@dots{}-foo>
+@end lisp
+
+As can be guessed, this primitive is cumbersome to use directly.  A better
+approach is to write build scripts in Scheme, of course! The best course of
+action for that is to write the build code as a ``G-expression'', and to
+pass it to @code{gexp->derivation}.  For more information,
+@pxref{G-Ausdrücke}.
+
+Once upon a time, @code{gexp->derivation} did not exist and constructing
+derivations with build code written in Scheme was achieved with
+@code{build-expression->derivation}, documented below.  This procedure is
+now deprecated in favor of the much nicer @code{gexp->derivation}.
+
+@deffn {Scheme Procedure} build-expression->derivation @var{store} @
+       @var{name} @var{exp} @ [#:system (%current-system)] [#:inputs '()] @
+[#:outputs '("out")] [#:hash #f] [#:hash-algo #f] @ [#:recursive? #f]
+[#:env-vars '()] [#:modules '()] @ [#:references-graphs #f]
+[#:allowed-references #f] @ [#:disallowed-references #f] @ [#:local-build?
+#f] [#:substitutable? #t] [#:guile-for-build #f] Return a derivation that
+executes Scheme expression @var{exp} as a builder for derivation
+@var{name}.  @var{inputs} must be a list of @code{(name drv-path sub-drv)}
+tuples; when @var{sub-drv} is omitted, @code{"out"} is assumed.
+@var{modules} is a list of names of Guile modules from the current search
+path to be copied in the store, compiled, and made available in the load
+path during the execution of @var{exp}---e.g., @code{((guix build utils)
+(guix build gnu-build-system))}.
+
+@var{exp} is evaluated in an environment where @code{%outputs} is bound to a
+list of output/path pairs, and where @code{%build-inputs} is bound to a list
+of string/output-path pairs made from @var{inputs}.  Optionally,
+@var{env-vars} is a list of string pairs specifying the name and value of
+environment variables visible to the builder.  The builder terminates by
+passing the result of @var{exp} to @code{exit}; thus, when @var{exp} returns
+@code{#f}, the build is considered to have failed.
+
+@var{exp} is built using @var{guile-for-build} (a derivation).  When
+@var{guile-for-build} is omitted or is @code{#f}, the value of the
+@code{%guile-for-build} fluid is used instead.
+
+See the @code{derivation} procedure for the meaning of
+@var{references-graphs}, @var{allowed-references},
+@var{disallowed-references}, @var{local-build?}, and @var{substitutable?}.

+@cindex monad
+
+The procedures that operate on the store described in the previous sections
+all take an open connection to the build daemon as their first argument.
+Although the underlying model is functional, they either have side effects
+or depend on the current state of the store.
+
+The former is inconvenient: the connection to the build daemon has to be
+carried around in all those functions, making it impossible to compose
+functions that do not take that parameter with functions that do.  The
+latter can be problematic: since store operations have side effects and/or
+depend on external state, they have to be properly sequenced.
+
+@cindex monadic values
+@cindex monadic functions
+This is where the @code{(guix monads)} module comes in.  This module
+provides a framework for working with @dfn{monads}, and a particularly
+useful monad for our uses, the @dfn{store monad}.  Monads are a construct
+that allows two things: associating ``context'' with values (in our case,
+the context is the store), and building sequences of computations (here
+computations include accesses to the store).  Values in a monad---values
+that carry this additional context---are called @dfn{monadic values};
+procedures that return such values are called @dfn{monadic procedures}.
+
+Consider this ``normal'' procedure:
+
+@example
+(define (sh-symlink store)
+  ;; Return a derivation that symlinks the 'bash' executable.
+  (let* ((drv (package-derivation store bash))
+         (out (derivation->output-path drv))
+         (sh  (string-append out "/bin/bash")))
+    (build-expression->derivation store "sh"
+                                  `(symlink ,sh %output))))
+@end example
+
+Using @code{(guix monads)} and @code{(guix gexp)}, it may be rewritten as a
+monadic function:
+
+@example
+(define (sh-symlink)
+  ;; Same, but return a monadic value.
+  (mlet %store-monad ((drv (package->derivation bash)))
+    (gexp->derivation "sh"
+                      #~(symlink (string-append #$drv "/bin/bash")
+                                 #$output))))
+@end example
+
+There are several things to note in the second version: the @code{store}
+parameter is now implicit and is ``threaded'' in the calls to the
+@code{package->derivation} and @code{gexp->derivation} monadic procedures,
+and the monadic value returned by @code{package->derivation} is @dfn{bound}
+using @code{mlet} instead of plain @code{let}.
+
+As it turns out, the call to @code{package->derivation} can even be omitted
+since it will take place implicitly, as we will see later
+(@pxref{G-Ausdrücke}):
+
+@example
+(define (sh-symlink)
+  (gexp->derivation "sh"
+                    #~(symlink (string-append #$bash "/bin/bash")
+                               #$output)))
+@end example
+
+@c See
+@c <https://syntaxexclamation.wordpress.com/2014/06/26/escaping-continuations/>
+@c for the funny quote.
+Calling the monadic @code{sh-symlink} has no effect.  As someone once said,
+``you exit a monad like you exit a building on fire: by running''.  So, to
+exit the monad and get the desired effect, one must use
+@code{run-with-store}:
+
+@example
+(run-with-store (open-connection) (sh-symlink))
+@result{} /gnu/store/...-sh-symlink
+@end example
+
+Note that the @code{(guix monad-repl)} module extends the Guile REPL with
+new ``meta-commands'' to make it easier to deal with monadic procedures:
+@code{run-in-store}, and @code{enter-store-monad}.  The former is used to
+``run'' a single monadic value through the store:
+
+@example
+scheme@@(guile-user)> ,run-in-store (package->derivation hello)
+$1 = #<derivation /gnu/store/@dots{}-hello-2.9.drv => @dots{}>
+@end example
+
+The latter enters a recursive REPL, where all the return values are
+automatically run through the store:
+
+@example
+scheme@@(guile-user)> ,enter-store-monad
+store-monad@@(guile-user) [1]> (package->derivation hello)
+$2 = #<derivation /gnu/store/@dots{}-hello-2.9.drv => @dots{}>
+store-monad@@(guile-user) [1]> (text-file "foo" "Hello!")
+$3 = "/gnu/store/@dots{}-foo"
+store-monad@@(guile-user) [1]> ,q
+scheme@@(guile-user)>
+@end example
+
+@noindent
+Note that non-monadic values cannot be returned in the @code{store-monad}
+REPL.
+
+The main syntactic forms to deal with monads in general are provided by the
+@code{(guix monads)} module and are described below.
+
+@deffn {Scheme Syntax} with-monad @var{monad} @var{body} ...
+Evaluate any @code{>>=} or @code{return} forms in @var{body} as being in
+@var{monad}.
+@end deffn
+
+@deffn {Scheme Syntax} return @var{val}
+Return a monadic value that encapsulates @var{val}.
+@end deffn
+
+@deffn {Scheme Syntax} >>= @var{mval} @var{mproc} ...
+@dfn{Bind} monadic value @var{mval}, passing its ``contents'' to monadic
+procedures @var{mproc}@dots{}@footnote{This operation is commonly referred
+to as ``bind'', but that name denotes an unrelated procedure in Guile.  Thus
+we use this somewhat cryptic symbol inherited from the Haskell language.}.
+There can be one @var{mproc} or several of them, as in this example:
+
+@example
+(run-with-state
+    (with-monad %state-monad
+      (>>= (return 1)
+           (lambda (x) (return (+ 1 x)))
+           (lambda (x) (return (* 2 x)))))
+  'some-state)
+
+@result{} 4
+@result{} some-state
+@end example
+@end deffn
+
+@deffn {Scheme Syntax} mlet @var{monad} ((@var{var} @var{mval}) ...) @
+       @var{body} ...
+@deffnx {Scheme Syntax} mlet* @var{monad} ((@var{var} @var{mval}) ...) @
+       @var{body} ...  Bind the variables @var{var} to the monadic values
+@var{mval} in @var{body}, which is a sequence of expressions.  As with the
+bind operator, this can be thought of as ``unpacking'' the raw, non-monadic
+value ``contained'' in @var{mval} and making @var{var} refer to that raw,
+non-monadic value within the scope of the @var{body}.  The form (@var{var}
+-> @var{val}) binds @var{var} to the ``normal'' value @var{val}, as per
+@code{let}.  The binding operations occur in sequence from left to right.
+The last expression of @var{body} must be a monadic expression, and its
+result will become the result of the @code{mlet} or @code{mlet*} when run in
+the @var{monad}.
+
+@code{mlet*} is to @code{mlet} what @code{let*} is to @code{let}
+(@pxref{Local Bindings,,, guile, GNU Guile Reference Manual}).
+@end deffn
+
+@deffn {Scheme System} mbegin @var{monad} @var{mexp} ...
+Bind @var{mexp} and the following monadic expressions in sequence, returning
+the result of the last expression.  Every expression in the sequence must be
+a monadic expression.
+
+This is akin to @code{mlet}, except that the return values of the monadic
+expressions are ignored.  In that sense, it is analogous to @code{begin},
+but applied to monadic expressions.
+@end deffn
+
+@deffn {Scheme System} mwhen @var{condition} @var{mexp0} @var{mexp*} ...
+When @var{condition} is true, evaluate the sequence of monadic expressions
+@var{mexp0}..@var{mexp*} as in an @code{mbegin}.  When @var{condition} is
+false, return @code{*unspecified*} in the current monad.  Every expression
+in the sequence must be a monadic expression.
+@end deffn
+
+@deffn {Scheme System} munless @var{condition} @var{mexp0} @var{mexp*} ...
+When @var{condition} is false, evaluate the sequence of monadic expressions
+@var{mexp0}..@var{mexp*} as in an @code{mbegin}.  When @var{condition} is
+true, return @code{*unspecified*} in the current monad.  Every expression in
+the sequence must be a monadic expression.
+@end deffn
+
+@cindex state monad
+The @code{(guix monads)} module provides the @dfn{state monad}, which allows
+an additional value---the state---to be @emph{threaded} through monadic
+procedure calls.
+
+@defvr {Scheme Variable} %state-monad
+The state monad.  Procedures in the state monad can access and change the
+state that is threaded.
+
+Consider the example below.  The @code{square} procedure returns a value in
+the state monad.  It returns the square of its argument, but also increments
+the current state value:
+
+@example
+(define (square x)
+  (mlet %state-monad ((count (current-state)))
+    (mbegin %state-monad
+      (set-current-state (+ 1 count))
+      (return (* x x)))))
+
+(run-with-state (sequence %state-monad (map square (iota 3))) 0)
+@result{} (0 1 4)
+@result{} 3
+@end example
+
+When ``run'' through @var{%state-monad}, we obtain that additional state
+value, which is the number of @code{square} calls.
+@end defvr
+
+@deffn {Monadic Procedure} current-state
+Return the current state as a monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} set-current-state @var{value}
+Set the current state to @var{value} and return the previous state as a
+monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} state-push @var{value}
+Push @var{value} to the current state, which is assumed to be a list, and
+return the previous state as a monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} state-pop
+Pop a value from the current state and return it as a monadic value.  The
+state is assumed to be a list.
+@end deffn
+
+@deffn {Scheme Procedure} run-with-state @var{mval} [@var{state}]
+Run monadic value @var{mval} starting with @var{state} as the initial
+state.  Return two values: the resulting value, and the resulting state.
+@end deffn
+
+The main interface to the store monad, provided by the @code{(guix store)}
+module, is as follows.
+
+@defvr {Scheme Variable} %store-monad
+The store monad---an alias for @var{%state-monad}.
+
+Values in the store monad encapsulate accesses to the store.  When its
+effect is needed, a value of the store monad must be ``evaluated'' by
+passing it to the @code{run-with-store} procedure (see below.)
+@end defvr
+
+@deffn {Scheme Procedure} run-with-store @var{store} @var{mval} [#:guile-for-build] [#:system (%current-system)]
+Run @var{mval}, a monadic value in the store monad, in @var{store}, an open
+store connection.
+@end deffn
+
+@deffn {Monadic Procedure} text-file @var{name} @var{text} [@var{references}]
+Return as a monadic value the absolute file name in the store of the file
+containing @var{text}, a string.  @var{references} is a list of store items
+that the resulting text file refers to; it defaults to the empty list.
+@end deffn
+
+@deffn {Monadic Procedure} binary-file @var{name} @var{data} [@var{references}]
+Return as a monadic value the absolute file name in the store of the file
+containing @var{data}, a bytevector.  @var{references} is a list of store
+items that the resulting binary file refers to; it defaults to the empty
+list.
+@end deffn
+
+@deffn {Monadic Procedure} interned-file @var{file} [@var{name}] @
+         [#:recursive? #t] [#:select? (const #t)] Return the name of @var{file} once
+interned in the store.  Use @var{name} as its store name, or the basename of
+@var{file} if @var{name} is omitted.
+
+When @var{recursive?} is true, the contents of @var{file} are added
+recursively; if @var{file} designates a flat file and @var{recursive?} is
+true, its contents are added, and its permission bits are kept.
+
+When @var{recursive?} is true, call @code{(@var{select?} @var{file}
+@var{stat})} for each directory entry, where @var{file} is the entry's
+absolute file name and @var{stat} is the result of @code{lstat}; exclude
+entries for which @var{select?} does not return true.
+
+The example below adds a file to the store, under two different names:
+
+@example
+(run-with-store (open-connection)
+  (mlet %store-monad ((a (interned-file "README"))
+                      (b (interned-file "README" "LEGU-MIN")))
+    (return (list a b))))
+
+@result{} ("/gnu/store/rwm@dots{}-README" "/gnu/store/44i@dots{}-LEGU-MIN")
+@end example
+
+@end deffn
+
+The @code{(guix packages)} module exports the following package-related
+monadic procedures:
+
+@deffn {Monadic Procedure} package-file @var{package} [@var{file}] @
+       [#:system (%current-system)] [#:target #f] @ [#:output "out"] Return as a
+monadic value in the absolute file name of @var{file} within the
+@var{output} directory of @var{package}.  When @var{file} is omitted, return
+the name of the @var{output} directory of @var{package}.  When @var{target}
+is true, use it as a cross-compilation target triplet.
+@end deffn

+@cindex G-expression
+@cindex build code quoting
+So we have ``derivations'', which represent a sequence of build actions to
+be performed to produce an item in the store (@pxref{Ableitungen}).  These
+build actions are performed when asking the daemon to actually build the
+derivations; they are run by the daemon in a container (@pxref{Aufruf des guix-daemon}).
+
+@cindex strata of code
+It should come as no surprise that we like to write these build actions in
+Scheme.  When we do that, we end up with two @dfn{strata} of Scheme
+code@footnote{The term @dfn{stratum} in this context was coined by Manuel
+Serrano et al.@: in the context of their work on Hop.  Oleg Kiselyov, who
+has written insightful
+@url{http://okmij.org/ftp/meta-programming/#meta-scheme, essays and code on
+this topic}, refers to this kind of code generation as @dfn{staging}.}: the
+``host code''---code that defines packages, talks to the daemon, etc.---and
+the ``build code''---code that actually performs build actions, such as
+making directories, invoking @command{make}, etc.
+
+To describe a derivation and its build actions, one typically needs to embed
+build code inside host code.  It boils down to manipulating build code as
+data, and the homoiconicity of Scheme---code has a direct representation as
+data---comes in handy for that.  But we need more than the normal
+@code{quasiquote} mechanism in Scheme to construct build expressions.
+
+The @code{(guix gexp)} module implements @dfn{G-expressions}, a form of
+S-expressions adapted to build expressions.  G-expressions, or @dfn{gexps},
+consist essentially of three syntactic forms: @code{gexp}, @code{ungexp},
+and @code{ungexp-splicing} (or simply: @code{#~}, @code{#$}, and
+@code{#$@@}), which are comparable to @code{quasiquote}, @code{unquote}, and
+@code{unquote-splicing}, respectively (@pxref{Expression Syntax,
+@code{quasiquote},, guile, GNU Guile Reference Manual}).  However, there are
+major differences:
+
+@itemize
+@item
+Gexps are meant to be written to a file and run or manipulated by other
+processes.
+
+@item
+When a high-level object such as a package or derivation is unquoted inside
+a gexp, the result is as if its output file name had been introduced.
+
+@item
+Gexps carry information about the packages or derivations they refer to, and
+these dependencies are automatically added as inputs to the build processes
+that use them.
+@end itemize
+
+@cindex lowering, of high-level objects in gexps
+This mechanism is not limited to package and derivation objects:
+@dfn{compilers} able to ``lower'' other high-level objects to derivations or
+files in the store can be defined, such that these objects can also be
+inserted into gexps.  For example, a useful type of high-level objects that
+can be inserted in a gexp is ``file-like objects'', which make it easy to
+add files to the store and to refer to them in derivations and such (see
+@code{local-file} and @code{plain-file} below.)
+
+To illustrate the idea, here is an example of a gexp:
+
+@example
+(define build-exp
+  #~(begin
+      (mkdir #$output)
+      (chdir #$output)
+      (symlink (string-append #$coreutils "/bin/ls")
+               "list-files")))
+@end example
+
+This gexp can be passed to @code{gexp->derivation}; we obtain a derivation
+that builds a directory containing exactly one symlink to
+@file{/gnu/store/@dots{}-coreutils-8.22/bin/ls}:
+
+@example
+(gexp->derivation "the-thing" build-exp)
+@end example
+
+As one would expect, the @code{"/gnu/store/@dots{}-coreutils-8.22"} string
+is substituted to the reference to the @var{coreutils} package in the actual
+build code, and @var{coreutils} is automatically made an input to the
+derivation.  Likewise, @code{#$output} (equivalent to @code{(ungexp
+output)}) is replaced by a string containing the directory name of the
+output of the derivation.
+
+@cindex cross compilation
+In a cross-compilation context, it is useful to distinguish between
+references to the @emph{native} build of a package---that can run on the
+host---versus references to cross builds of a package.  To that end, the
+@code{#+} plays the same role as @code{#$}, but is a reference to a native
+package build:
+
+@example
+(gexp->derivation "vi"
+   #~(begin
+       (mkdir #$output)
+       (system* (string-append #+coreutils "/bin/ln")
+                "-s"
+                (string-append #$emacs "/bin/emacs")
+                (string-append #$output "/bin/vi")))
+   #:target "mips64el-linux-gnu")
+@end example
+
+@noindent
+In the example above, the native build of @var{coreutils} is used, so that
+@command{ln} can actually run on the host; but then the cross-compiled build
+of @var{emacs} is referenced.
+
+@cindex imported modules, for gexps
+@findex with-imported-modules
+Another gexp feature is @dfn{imported modules}: sometimes you want to be
+able to use certain Guile modules from the ``host environment'' in the gexp,
+so those modules should be imported in the ``build environment''.  The
+@code{with-imported-modules} form allows you to express that:
+
+@example
+(let ((build (with-imported-modules '((guix build utils))
+               #~(begin
+                   (use-modules (guix build utils))
+                   (mkdir-p (string-append #$output "/bin"))))))
+  (gexp->derivation "empty-dir"
+                    #~(begin
+                        #$build
+                        (display "success!\n")
+                        #t)))
+@end example
+
+@noindent
+In this example, the @code{(guix build utils)} module is automatically
+pulled into the isolated build environment of our gexp, such that
+@code{(use-modules (guix build utils))} works as expected.
+
+@cindex module closure
+@findex source-module-closure
+Usually you want the @emph{closure} of the module to be imported---i.e., the
+module itself and all the modules it depends on---rather than just the
+module; failing to do that, attempts to use the module will fail because of
+missing dependent modules.  The @code{source-module-closure} procedure
+computes the closure of a module by looking at its source file headers,
+which comes in handy in this case:
+
+@example
+(use-modules (guix modules))   ;for 'source-module-closure'
+
+(with-imported-modules (source-module-closure
+                         '((guix build utils)
+                           (gnu build vm)))
+  (gexp->derivation "something-with-vms"
+                    #~(begin
+                        (use-modules (guix build utils)
+                                     (gnu build vm))
+                        @dots{})))
+@end example
+
+@cindex extensions, for gexps
+@findex with-extensions
+In the same vein, sometimes you want to import not just pure-Scheme modules,
+but also ``extensions'' such as Guile bindings to C libraries or other
+``full-blown'' packages.  Say you need the @code{guile-json} package
+available on the build side, here's how you would do it:
+
+@example
+(use-modules (gnu packages guile))  ;for 'guile-json'
+
+(with-extensions (list guile-json)
+  (gexp->derivation "something-with-json"
+                    #~(begin
+                        (use-modules (json))
+                        @dots{})))
+@end example
+
+The syntactic form to construct gexps is summarized below.
+
+@deffn {Scheme Syntax} #~@var{exp}
+@deffnx {Scheme Syntax} (gexp @var{exp})
+Return a G-expression containing @var{exp}.  @var{exp} may contain one or
+more of the following forms:
+
+@table @code
+@item #$@var{obj}
+@itemx (ungexp @var{obj})
+Introduce a reference to @var{obj}.  @var{obj} may have one of the supported
+types, for example a package or a derivation, in which case the
+@code{ungexp} form is replaced by its output file name---e.g.,
+@code{"/gnu/store/@dots{}-coreutils-8.22}.
+
+If @var{obj} is a list, it is traversed and references to supported objects
+are substituted similarly.
+
+If @var{obj} is another gexp, its contents are inserted and its dependencies
+are added to those of the containing gexp.
+
+If @var{obj} is another kind of object, it is inserted as is.
+
+@item #$@var{obj}:@var{output}
+@itemx (ungexp @var{obj} @var{output})
+This is like the form above, but referring explicitly to the @var{output} of
+@var{obj}---this is useful when @var{obj} produces multiple outputs
+(@pxref{Pakete mit mehreren Ausgaben.}).
+
+@item #+@var{obj}
+@itemx #+@var{obj}:output
+@itemx (ungexp-native @var{obj})
+@itemx (ungexp-native @var{obj} @var{output})
+Same as @code{ungexp}, but produces a reference to the @emph{native} build
+of @var{obj} when used in a cross compilation context.
+
+@item #$output[:@var{output}]
+@itemx (ungexp output [@var{output}])
+Insert a reference to derivation output @var{output}, or to the main output
+when @var{output} is omitted.
+
+This only makes sense for gexps passed to @code{gexp->derivation}.
+
+@item #$@@@var{lst}
+@itemx (ungexp-splicing @var{lst})
+Like the above, but splices the contents of @var{lst} inside the containing
+list.
+
+@item #+@@@var{lst}
+@itemx (ungexp-native-splicing @var{lst})
+Like the above, but refers to native builds of the objects listed in
+@var{lst}.
+
+@end table
+
+G-expressions created by @code{gexp} or @code{#~} are run-time objects of
+the @code{gexp?} type (see below.)
+@end deffn
+
+@deffn {Scheme Syntax} with-imported-modules @var{modules} @var{body}@dots{}
+Mark the gexps defined in @var{body}@dots{} as requiring @var{modules} in
+their execution environment.
+
+Each item in @var{modules} can be the name of a module, such as @code{(guix
+build utils)}, or it can be a module name, followed by an arrow, followed by
+a file-like object:
+
+@example
+`((guix build utils)
+  (guix gcrypt)
+  ((guix config) => ,(scheme-file "config.scm"
+                                  #~(define-module @dots{}))))
+@end example
+
+@noindent
+In the example above, the first two modules are taken from the search path,
+and the last one is created from the given file-like object.
+
+This form has @emph{lexical} scope: it has an effect on the gexps directly
+defined in @var{body}@dots{}, but not on those defined, say, in procedures
+called from @var{body}@dots{}.
+@end deffn
+
+@deffn {Scheme Syntax} with-extensions @var{extensions} @var{body}@dots{}
+Mark the gexps defined in @var{body}@dots{} as requiring @var{extensions} in
+their build and execution environment.  @var{extensions} is typically a list
+of package objects such as those defined in the @code{(gnu packages guile)}
+module.
+
+Concretely, the packages listed in @var{extensions} are added to the load
+path while compiling imported modules in @var{body}@dots{}; they are also
+added to the load path of the gexp returned by @var{body}@dots{}.
+@end deffn
+
+@deffn {Scheme Procedure} gexp? @var{obj}
+Return @code{#t} if @var{obj} is a G-expression.
+@end deffn
+
+G-expressions are meant to be written to disk, either as code building some
+derivation, or as plain files in the store.  The monadic procedures below
+allow you to do that (@pxref{Die Store-Monade}, for more information about
+monads.)
+
+@deffn {Monadic Procedure} gexp->derivation @var{name} @var{exp} @
+       [#:system (%current-system)] [#:target #f] [#:graft? #t] @ [#:hash #f]
+[#:hash-algo #f] @ [#:recursive? #f] [#:env-vars '()] [#:modules '()] @
+[#:module-path @var{%load-path}] @ [#:effective-version "2.2"] @
+[#:references-graphs #f] [#:allowed-references #f] @
+[#:disallowed-references #f] @ [#:leaked-env-vars #f] @ [#:script-name
+(string-append @var{name} "-builder")] @ [#:deprecation-warnings #f] @
+[#:local-build? #f] [#:substitutable? #t] @ [#:properties '()]
+[#:guile-for-build #f] Return a derivation @var{name} that runs @var{exp} (a
+gexp) with @var{guile-for-build} (a derivation) on @var{system}; @var{exp}
+is stored in a file called @var{script-name}.  When @var{target} is true, it
+is used as the cross-compilation target triplet for packages referred to by
+@var{exp}.
+
+@var{modules} is deprecated in favor of @code{with-imported-modules}.  Its
+meaning is to make @var{modules} available in the evaluation context of
+@var{exp}; @var{modules} is a list of names of Guile modules searched in
+@var{module-path} to be copied in the store, compiled, and made available in
+the load path during the execution of @var{exp}---e.g., @code{((guix build
+utils) (guix build gnu-build-system))}.
+
+@var{effective-version} determines the string to use when adding extensions
+of @var{exp} (see @code{with-extensions}) to the search path---e.g.,
+@code{"2.2"}.
+
+@var{graft?} determines whether packages referred to by @var{exp} should be
+grafted when applicable.
+
+When @var{references-graphs} is true, it must be a list of tuples of one of
+the following forms:
+
+@example
+(@var{file-name} @var{package})
+(@var{file-name} @var{package} @var{output})
+(@var{file-name} @var{derivation})
+(@var{file-name} @var{derivation} @var{output})
+(@var{file-name} @var{store-item})
+@end example
+
+The right-hand-side of each element of @var{references-graphs} is
+automatically made an input of the build process of @var{exp}.  In the build
+environment, each @var{file-name} contains the reference graph of the
+corresponding item, in a simple text format.
+
+@var{allowed-references} must be either @code{#f} or a list of output names
+and packages.  In the latter case, the list denotes store items that the
+result is allowed to refer to.  Any reference to another store item will
+lead to a build error.  Similarly for @var{disallowed-references}, which can
+list items that must not be referenced by the outputs.
+
+@var{deprecation-warnings} determines whether to show deprecation warnings
+while compiling modules.  It can be @code{#f}, @code{#t}, or
+@code{'detailed}.
+
+The other arguments are as for @code{derivation} (@pxref{Ableitungen}).
+@end deffn
+
+@cindex file-like objects
+The @code{local-file}, @code{plain-file}, @code{computed-file},
+@code{program-file}, and @code{scheme-file} procedures below return
+@dfn{file-like objects}.  That is, when unquoted in a G-expression, these
+objects lead to a file in the store.  Consider this G-expression:
+
+@example
+#~(system* #$(file-append glibc "/sbin/nscd") "-f"
+           #$(local-file "/tmp/my-nscd.conf"))
+@end example
+
+The effect here is to ``intern'' @file{/tmp/my-nscd.conf} by copying it to
+the store.  Once expanded, for instance @i{via} @code{gexp->derivation}, the
+G-expression refers to that copy under @file{/gnu/store}; thus, modifying or
+removing the file in @file{/tmp} does not have any effect on what the
+G-expression does.  @code{plain-file} can be used similarly; it differs in
+that the file content is directly passed as a string.
+
+@deffn {Scheme Procedure} local-file @var{file} [@var{name}] @
+   [#:recursive? #f] [#:select? (const #t)] Return an object representing local
+file @var{file} to add to the store; this object can be used in a gexp.  If
+@var{file} is a relative file name, it is looked up relative to the source
+file where this form appears.  @var{file} will be added to the store under
+@var{name}--by default the base name of @var{file}.
+
+When @var{recursive?} is true, the contents of @var{file} are added
+recursively; if @var{file} designates a flat file and @var{recursive?} is
+true, its contents are added, and its permission bits are kept.
+
+When @var{recursive?} is true, call @code{(@var{select?} @var{file}
+@var{stat})} for each directory entry, where @var{file} is the entry's
+absolute file name and @var{stat} is the result of @code{lstat}; exclude
+entries for which @var{select?} does not return true.
+
+This is the declarative counterpart of the @code{interned-file} monadic
+procedure (@pxref{Die Store-Monade, @code{interned-file}}).
+@end deffn
+
+@deffn {Scheme Procedure} plain-file @var{name} @var{content}
+Return an object representing a text file called @var{name} with the given
+@var{content} (a string or a bytevector) to be added to the store.
+
+This is the declarative counterpart of @code{text-file}.
+@end deffn
+
+@deffn {Scheme Procedure} computed-file @var{name} @var{gexp} @
+          [#:options '(#:local-build? #t)] Return an object representing the store
+item @var{name}, a file or directory computed by @var{gexp}.  @var{options}
+is a list of additional arguments to pass to @code{gexp->derivation}.
+
+This is the declarative counterpart of @code{gexp->derivation}.
+@end deffn
+
+@deffn {Monadic Procedure} gexp->script @var{name} @var{exp} @
+  [#:guile (default-guile)] [#:module-path %load-path] Return an executable
+script @var{name} that runs @var{exp} using @var{guile}, with @var{exp}'s
+imported modules in its search path.  Look up @var{exp}'s modules in
+@var{module-path}.
+
+The example below builds a script that simply invokes the @command{ls}
+command:
+
+@example
+(use-modules (guix gexp) (gnu packages base))
+
+(gexp->script "list-files"
+              #~(execl #$(file-append coreutils "/bin/ls")
+                       "ls"))
+@end example
+
+When ``running'' it through the store (@pxref{Die Store-Monade,
+@code{run-with-store}}), we obtain a derivation that produces an executable
+file @file{/gnu/store/@dots{}-list-files} along these lines:
+
+@example
+#!/gnu/store/@dots{}-guile-2.0.11/bin/guile -ds
+!#
+(execl "/gnu/store/@dots{}-coreutils-8.22"/bin/ls" "ls")
+@end example
+@end deffn
+
+@deffn {Scheme Procedure} program-file @var{name} @var{exp} @
+          [#:guile #f] [#:module-path %load-path] Return an object representing the
+executable store item @var{name} that runs @var{gexp}.  @var{guile} is the
+Guile package used to execute that script.  Imported modules of @var{gexp}
+are looked up in @var{module-path}.
+
+This is the declarative counterpart of @code{gexp->script}.
+@end deffn
+
+@deffn {Monadic Procedure} gexp->file @var{name} @var{exp} @
+            [#:set-load-path? #t] [#:module-path %load-path] @ [#:splice? #f] @ [#:guile
+(default-guile)] Return a derivation that builds a file @var{name}
+containing @var{exp}.  When @var{splice?} is true, @var{exp} is considered
+to be a list of expressions that will be spliced in the resulting file.
+
+When @var{set-load-path?} is true, emit code in the resulting file to set
+@code{%load-path} and @code{%load-compiled-path} to honor @var{exp}'s
+imported modules.  Look up @var{exp}'s modules in @var{module-path}.
+
+The resulting file holds references to all the dependencies of @var{exp} or
+a subset thereof.
+@end deffn
+
+@deffn {Scheme Procedure} scheme-file @var{name} @var{exp} [#:splice? #f]
+Return an object representing the Scheme file @var{name} that contains
+@var{exp}.
+
+This is the declarative counterpart of @code{gexp->file}.
+@end deffn
+
+@deffn {Monadic Procedure} text-file* @var{name} @var{text} @dots{}
+Return as a monadic value a derivation that builds a text file containing
+all of @var{text}.  @var{text} may list, in addition to strings, objects of
+any type that can be used in a gexp: packages, derivations, local file
+objects, etc.  The resulting store file holds references to all these.
+
+This variant should be preferred over @code{text-file} anytime the file to
+create will reference items from the store.  This is typically the case when
+building a configuration file that embeds store file names, like this:
+
+@example
+(define (profile.sh)
+  ;; Return the name of a shell script in the store that
+  ;; initializes the 'PATH' environment variable.
+  (text-file* "profile.sh"
+              "export PATH=" coreutils "/bin:"
+              grep "/bin:" sed "/bin\n"))
+@end example
+
+In this example, the resulting @file{/gnu/store/@dots{}-profile.sh} file
+will reference @var{coreutils}, @var{grep}, and @var{sed}, thereby
+preventing them from being garbage-collected during its lifetime.
+@end deffn
+
+@deffn {Scheme Procedure} mixed-text-file @var{name} @var{text} @dots{}
+Return an object representing store file @var{name} containing @var{text}.
+@var{text} is a sequence of strings and file-like objects, as in:
+
+@example
+(mixed-text-file "profile"
+                 "export PATH=" coreutils "/bin:" grep "/bin")
+@end example
+
+This is the declarative counterpart of @code{text-file*}.
+@end deffn
+
+@deffn {Scheme Procedure} file-union @var{name} @var{files}
+Return a @code{<computed-file>} that builds a directory containing all of
+@var{files}.  Each item in @var{files} must be a two-element list where the
+first element is the file name to use in the new directory, and the second
+element is a gexp denoting the target file.  Here's an example:
+
+@example
+(file-union "etc"
+            `(("hosts" ,(plain-file "hosts"
+                                    "127.0.0.1 localhost"))
+              ("bashrc" ,(plain-file "bashrc"
+                                     "alias ls='ls --color=auto'"))))
+@end example
+
+This yields an @code{etc} directory containing these two files.
+@end deffn
+
+@deffn {Scheme Procedure} directory-union @var{name} @var{things}
+Return a directory that is the union of @var{things}, where @var{things} is
+a list of file-like objects denoting directories.  For example:
+
+@example
+(directory-union "guile+emacs" (list guile emacs))
+@end example
+
+yields a directory that is the union of the @code{guile} and @code{emacs}
+packages.
+@end deffn
+
+@deffn {Scheme Procedure} file-append @var{obj} @var{suffix} @dots{}
+Return a file-like object that expands to the concatenation of @var{obj} and
+@var{suffix}, where @var{obj} is a lowerable object and each @var{suffix} is
+a string.
+
+As an example, consider this gexp:
+
+@example
+(gexp->script "run-uname"
+              #~(system* #$(file-append coreutils
+                                        "/bin/uname")))
+@end example
+
+The same effect could be achieved with:
+
+@example
+(gexp->script "run-uname"
+              #~(system* (string-append #$coreutils
+                                        "/bin/uname")))
+@end example
+
+There is one difference though: in the @code{file-append} case, the
+resulting script contains the absolute file name as a string, whereas in the
+second case, the resulting script contains a @code{(string-append @dots{})}
+expression to construct the file name @emph{at run time}.
+@end deffn
+
+
+Of course, in addition to gexps embedded in ``host'' code, there are also
+modules containing build tools.  To make it clear that they are meant to be
+used in the build stratum, these modules are kept in the @code{(guix build
+@dots{})} name space.
+
+@cindex lowering, of high-level objects in gexps
+Internally, high-level objects are @dfn{lowered}, using their compiler, to
+either derivations or store items.  For instance, lowering a package yields
+a derivation, and lowering a @code{plain-file} yields a store item.  This is
+achieved using the @code{lower-object} monadic procedure.
+
+@deffn {Monadic Procedure} lower-object @var{obj} [@var{system}] @
+           [#:target #f] Return as a value in @var{%store-monad} the derivation or
+store item corresponding to @var{obj} for @var{system}, cross-compiling for
+@var{target} if @var{target} is true.  @var{obj} must be an object that has
+an associated gexp compiler, such as a @code{<package>}.

+@cindex REPL, read-eval-print loop
+The @command{guix repl} command spawns a Guile @dfn{read-eval-print loop}
+(REPL) for interactive programming (@pxref{Using Guile Interactively,,,
+guile, GNU Guile Reference Manual}).  Compared to just launching the
+@command{guile} command, @command{guix repl} guarantees that all the Guix
+modules and all its dependencies are available in the search path.  You can
+use it this way:
+
+@example
+$ guix repl
+scheme@@(guile-user)> ,use (gnu packages base)
+scheme@@(guile-user)> coreutils
+$1 = #<package coreutils@@8.29 gnu/packages/base.scm:327 3e28300>
+@end example
+
+@cindex inferiors
+In addition, @command{guix repl} implements a simple machine-readable REPL
+protocol for use by @code{(guix inferior)}, a facility to interact with
+@dfn{inferiors}, separate processes running a potentially different revision
+of Guix.
+
+The available options are as follows:
+
+@table @code
+@item --type=@var{type}
+@itemx -t @var{type}
+Start a REPL of the given @var{TYPE}, which can be one of the following:
+
+@table @code
+@item guile
+This is default, and it spawns a standard full-featured Guile REPL.
+@item machine
+Spawn a REPL that uses the machine-readable protocol.  This is the protocol
+that the @code{(guix inferior)} module speaks.
+@end table
+
+@item --listen=@var{Endpunkt}
+By default, @command{guix repl} reads from standard input and writes to
+standard output.  When this option is passed, it will instead listen for
+connections on @var{endpoint}.  Here are examples of valid options:
+
+@table @code
+@item --listen=tcp:37146
+Accept connections on localhost on port 37146.
+
+@item --listen=unix:/tmp/socket
+Accept connections on the Unix-domain socket @file{/tmp/socket}.

+@cindex package building
+@cindex @command{guix build}
+The @command{guix build} command builds packages or derivations and their
+dependencies, and prints the resulting store paths.  Note that it does not
+modify the user's profile---this is the job of the @command{guix package}
+command (@pxref{Aufruf von guix package}).  Thus, it is mainly useful for
+distribution developers.
+
+The general syntax is:
+
+@example
+guix build @var{options} @var{package-or-derivation}@dots{}
+@end example
+
+As an example, the following command builds the latest versions of Emacs and
+of Guile, displays their build logs, and finally displays the resulting
+directories:
+
+@example
+guix build emacs guile
+@end example
+
+Similarly, the following command builds all the available packages:
+
+@example
+guix build --quiet --keep-going \
+  `guix package -A | cut -f1,2 --output-delimiter=@@`
+@end example
+
+@var{package-or-derivation} may be either the name of a package found in the
+software distribution such as @code{coreutils} or @code{coreutils@@8.20}, or
+a derivation such as @file{/gnu/store/@dots{}-coreutils-8.19.drv}.  In the
+former case, a package with the corresponding name (and optionally version)
+is searched for among the GNU distribution modules (@pxref{Paketmodule}).
+
+Alternatively, the @code{--expression} option may be used to specify a
+Scheme expression that evaluates to a package; this is useful when
+disambiguating among several same-named packages or package variants is
+needed.
+
+There may be zero or more @var{options}.  The available options are
+described in the subsections below.

+@node Gemeinsame Erstellungsoptionen
+@subsection Gemeinsame Erstellungsoptionen
+
+A number of options that control the build process are common to
+@command{guix build} and other commands that can spawn builds, such as
+@command{guix package} or @command{guix archive}.  These are the following:
+
+@table @code
+
+@item --load-path=@var{directory}
+@itemx -L @var{directory}
+Add @var{directory} to the front of the package module search path
+(@pxref{Paketmodule}).
+
+This allows users to define their own packages and make them visible to the
+command-line tools.
+
+@item --keep-failed
+@itemx -K
+Keep the build tree of failed builds.  Thus, if a build fails, its build
+tree is kept under @file{/tmp}, in a directory whose name is shown at the
+end of the build log.  This is useful when debugging build issues.
+@xref{Fehlschläge beim Erstellen untersuchen}, for tips and tricks on how to debug build
+issues.
+
+This option has no effect when connecting to a remote daemon with a
+@code{guix://} URI (@pxref{Der Store, the @code{GUIX_DAEMON_SOCKET}
+variable}).
+
+@item --keep-going
+@itemx -k
+Keep going when some of the derivations fail to build; return only once all
+the builds have either completed or failed.
+
+The default behavior is to stop as soon as one of the specified derivations
+has failed.
+
+@item --dry-run
+@itemx -n
+Do not build the derivations.
+
+@anchor{fallback-option}
+@item --fallback
+When substituting a pre-built binary fails, fall back to building packages
+locally (@pxref{Fehler bei der Substitution}).
+
+@item --substitute-urls=@var{URLs}
+@anchor{client-substitute-urls}
+Consider @var{urls} the whitespace-separated list of substitute source URLs,
+overriding the default list of URLs of @command{guix-daemon}
+(@pxref{daemon-substitute-urls,, @command{guix-daemon} URLs}).
+
+This means that substitutes may be downloaded from @var{urls}, provided they
+are signed by a key authorized by the system administrator
+(@pxref{Substitute}).
+
+When @var{urls} is the empty string, substitutes are effectively disabled.
+
+@item --no-substitutes
+Benutze keine Substitute für Erstellungsergebnisse. Das heißt, dass alle
+Objekte lokal erstellt werden müssen, und kein Herunterladen von vorab
+erstellten Binärdateien erlaubt ist (@pxref{Substitute}).
+
+@item --no-grafts
+Do not ``graft'' packages.  In practice, this means that package updates
+available as grafts are not applied.  @xref{Sicherheitsaktualisierungen}, for more
+information on grafts.
+
+@item --rounds=@var{n}
+Build each derivation @var{n} times in a row, and raise an error if
+consecutive build results are not bit-for-bit identical.
+
+This is a useful way to detect non-deterministic builds processes.
+Non-deterministic build processes are a problem because they make it
+practically impossible for users to @emph{verify} whether third-party
+binaries are genuine.  @xref{Aufruf von guix challenge}, for more.
+
+Note that, currently, the differing build results are not kept around, so
+you will have to manually investigate in case of an error---e.g., by
+stashing one of the build results with @code{guix archive --export}
+(@pxref{Aufruf von guix archive}), then rebuilding, and finally comparing the
+two results.
+
+@item --no-build-hook
+Nicht versuchen, Erstellungen über den »Build-Hook« des Daemons auszulagern
+(@pxref{Auslagern des Daemons einrichten}). Somit wird lokal erstellt, statt
+Erstellungen auf entfernte Maschinen auszulagern.
+
+@item --max-silent-time=@var{Sekunden}

+
+In addition to options explicitly passed on the command line, @command{guix

+@cindex package variants
+Another set of command-line options supported by @command{guix build} and
+also @command{guix package} are @dfn{package transformation options}.  These
+are options that make it possible to define @dfn{package variants}---for
+instance, packages built from different source code.  This is a convenient
+way to create customized packages on the fly without having to type in the
+definitions of package variants (@pxref{Pakete definieren}).
+
+@table @code
+
+@item --with-source=@var{source}
+@itemx --with-source=@var{package}=@var{source}
+@itemx --with-source=@var{package}@@@var{version}=@var{source}
+Use @var{source} as the source of @var{package}, and @var{version} as its
+version number.  @var{source} must be a file name or a URL, as for
+@command{guix download} (@pxref{Aufruf von guix download}).
+
+When @var{package} is omitted, it is taken to be the package name specified
+on the command line that matches the base of @var{source}---e.g., if
+@var{source} is @code{/src/guile-2.0.10.tar.gz}, the corresponding package
+is @code{guile}.
+
+Likewise, when @var{version} is omitted, the version string is inferred from
+@var{source}; in the previous example, it is @code{2.0.10}.
+
+This option allows users to try out versions of packages other than the one
+provided by the distribution.  The example below downloads
+@file{ed-1.7.tar.gz} from a GNU mirror and uses that as the source for the
+@code{ed} package:
+
+@example
+guix build ed --with-source=mirror://gnu/ed/ed-1.7.tar.gz
+@end example
+
+As a developer, @code{--with-source} makes it easy to test release
+candidates:
+
+@example
+guix build guile --with-source=../guile-2.0.9.219-e1bb7.tar.xz
+@end example
+
+@dots{} or to build from a checkout in a pristine environment:
+
+@example
+$ git clone git://git.sv.gnu.org/guix.git
+$ guix build guix --with-source=guix@@1.0=./guix
+@end example
+
+@item --with-input=@var{package}=@var{replacement}
+Replace dependency on @var{package} by a dependency on @var{replacement}.
+@var{package} must be a package name, and @var{replacement} must be a
+package specification such as @code{guile} or @code{guile@@1.8}.
+
+For instance, the following command builds Guix, but replaces its dependency
+on the current stable version of Guile with a dependency on the legacy
+version of Guile, @code{guile@@2.0}:
+
+@example
+guix build --with-input=guile=guile@@2.0 guix
+@end example
+
+This is a recursive, deep replacement.  So in this example, both @code{guix}
+and its dependency @code{guile-json} (which also depends on @code{guile})
+get rebuilt against @code{guile@@2.0}.
+
+This is implemented using the @code{package-input-rewriting} Scheme
+procedure (@pxref{Pakete definieren, @code{package-input-rewriting}}).
+
+@item --with-graft=@var{package}=@var{replacement}
+This is similar to @code{--with-input} but with an important difference:
+instead of rebuilding the whole dependency chain, @var{replacement} is built
+and then @dfn{grafted} onto the binaries that were initially referring to
+@var{package}.  @xref{Sicherheitsaktualisierungen}, for more information on grafts.
+
+For example, the command below grafts version 3.5.4 of GnuTLS onto Wget and
+all its dependencies, replacing references to the version of GnuTLS they
+currently refer to:
+
+@example
+guix build --with-graft=gnutls=gnutls@@3.5.4 wget
+@end example
+
+This has the advantage of being much faster than rebuilding everything.  But
+there is a caveat: it works if and only if @var{package} and
+@var{replacement} are strictly compatible---for example, if they provide a
+library, the application binary interface (ABI) of those libraries must be
+compatible.  If @var{replacement} is somehow incompatible with
+@var{package}, then the resulting package may be unusable.  Use with care!
+
+@item --with-branch=@var{package}=@var{branch}
+@cindex Git, using the latest commit
+@cindex latest commit, building
+Build @var{package} from the latest commit of @var{branch}.  The
+@code{source} field of @var{package} must be an origin with the
+@code{git-fetch} method (@pxref{„origin“-Referenz}) or a @code{git-checkout}
+object; the repository URL is taken from that @code{source}.
+
+For instance, the following command builds @code{guile-sqlite3} from the
+latest commit of its @code{master} branch, and then builds @code{guix}
+(which depends on it) and @code{cuirass} (which depends on @code{guix})
+against this specific @code{guile-sqlite3} build:
+
+@example
+guix build --with-branch=guile-sqlite3=master cuirass
+@end example
+
+@cindex continuous integration
+Obviously, since it uses the latest commit of the given branch, the result
+of such a command varies over time.  Nevertheless it is a convenient way to
+rebuild entire software stacks against the latest commit of one or more
+packages.  This is particularly useful in the context of continuous
+integration (CI).
+
+Checkouts are kept in a cache under @file{~/.cache/guix/checkouts} to speed
+up consecutive accesses to the same repository.  You may want to clean it up
+once in a while to save disk space.
+
+@item --with-commit=@var{package}=@var{commit}
+This is similar to @code{--with-branch}, except that it builds from
+@var{commit} rather than the tip of a branch.  @var{commit} must be a valid
+Git commit SHA1 identifier.

+@subsection Zusätzliche Erstellungsoptionen
+
+The command-line options presented below are specific to @command{guix
+build}.
+
+@table @code
+
+@item --quiet
+@itemx -q
+Build quietly, without displaying the build log.  Upon completion, the build
+log is kept in @file{/var} (or similar) and can always be retrieved using
+the @option{--log-file} option.
+
+@item --file=@var{file}
+@itemx -f @var{Datei}
+Build the package, derivation, or other file-like object that the code
+within @var{file} evaluates to (@pxref{G-Ausdrücke, file-like objects}).
+
+As an example, @var{file} might contain a package definition like this
+(@pxref{Pakete definieren}):
+
+@example
+@verbatiminclude package-hello.scm
+@end example
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Build the package or derivation @var{expr} evaluates to.
+
+For example, @var{expr} may be @code{(@@ (gnu packages guile)  guile-1.8)},
+which unambiguously designates this specific variant of version 1.8 of
+Guile.
+
+Alternatively, @var{expr} may be a G-expression, in which case it is used as
+a build program passed to @code{gexp->derivation} (@pxref{G-Ausdrücke}).
+
+Lastly, @var{expr} may refer to a zero-argument monadic procedure
+(@pxref{Die Store-Monade}).  The procedure must return a derivation as a
+monadic value, which is then passed through @code{run-with-store}.
+
+@item --source
+@itemx -S
+Build the source derivations of the packages, rather than the packages
+themselves.
+
+For instance, @code{guix build -S gcc} returns something like
+@file{/gnu/store/@dots{}-gcc-4.7.2.tar.bz2}, which is the GCC source
+tarball.
+
+The returned source tarball is the result of applying any patches and code
+snippets specified in the package @code{origin} (@pxref{Pakete definieren}).
+
+@item --sources
+Fetch and return the source of @var{package-or-derivation} and all their
+dependencies, recursively.  This is a handy way to obtain a local copy of
+all the source code needed to build @var{packages}, allowing you to
+eventually build them even without network access.  It is an extension of
+the @code{--source} option and can accept one of the following optional
+argument values:
+
+@table @code
+@item package
+This value causes the @code{--sources} option to behave in the same way as
+the @code{--source} option.
+
+@item all
+Build the source derivations of all packages, including any source that
+might be listed as @code{inputs}.  This is the default value.
+
+@example
+$ guix build --sources tzdata
+The following derivations will be built:
+   /gnu/store/@dots{}-tzdata2015b.tar.gz.drv
+   /gnu/store/@dots{}-tzcode2015b.tar.gz.drv
+@end example
+
+@item transitive
+Build the source derivations of all packages, as well of all transitive
+inputs to the packages.  This can be used e.g.@: to prefetch package source
+for later offline building.
+
+@example
+$ guix build --sources=transitive tzdata
+The following derivations will be built:
+   /gnu/store/@dots{}-tzcode2015b.tar.gz.drv
+   /gnu/store/@dots{}-findutils-4.4.2.tar.xz.drv

+
+Similarly, when transparent emulation with QEMU and @code{binfmt_misc} is

+
+@item --log-file
+@cindex build logs, access
+Return the build log file names or URLs for the given

+
+This works regardless of how packages or derivations are specified.  For

+
+@example
+guix build --log-file `guix build -d guile`
+guix build --log-file `guix build guile`
+guix build --log-file guile
+guix build --log-file -e '(@@ (gnu packages guile) guile-2.0)'
+@end example
+
+If a log is unavailable locally, and unless @code{--no-substitutes} is
+passed, the command looks for a corresponding log on one of the substitute
+servers (as specified with @code{--substitute-urls}.)
+
+So for instance, imagine you want to see the build log of GDB on MIPS, but
+you are actually on an @code{x86_64} machine:
+
+@example
+$ guix build --log-file gdb -s mips64el-linux

+@end example
+
+You can freely access a huge library of build logs!

+@node Fehlschläge beim Erstellen untersuchen
+@subsection Fehlschläge beim Erstellen untersuchen
+
+@cindex build failures, debugging
+When defining a new package (@pxref{Pakete definieren}), you will probably
+find yourself spending some time debugging and tweaking the build until it
+succeeds.  To do that, you need to operate the build commands yourself in an
+environment as close as possible to the one the build daemon uses.
+
+To that end, the first thing to do is to use the @option{--keep-failed} or
+@option{-K} option of @command{guix build}, which will keep the failed build
+tree in @file{/tmp} or whatever directory you specified as @code{TMPDIR}
+(@pxref{Aufruf von guix build, @code{--keep-failed}}).
+
+From there on, you can @command{cd} to the failed build tree and source the
+@file{environment-variables} file, which contains all the environment
+variable definitions that were in place when the build failed.  So let's say
+you're debugging a build failure in package @code{foo}; a typical session
+would look like this:
+
+@example
+$ guix build foo -K
+@dots{} @i{build fails}
+$ cd /tmp/guix-build-foo.drv-0
+$ source ./environment-variables
+$ cd foo-1.2
+@end example
+
+Now, you can invoke commands as if you were the daemon (almost) and
+troubleshoot your build process.
+
+Sometimes it happens that, for example, a package's tests pass when you run
+them manually but they fail when the daemon runs them.  This can happen
+because the daemon runs builds in containers where, unlike in our
+environment above, network access is missing, @file{/bin/sh} does not exist,
+etc. (@pxref{Einrichten der Erstellungsumgebung}).
+
+In such cases, you may need to run inspect the build process from within a
+container similar to the one the build daemon creates:
+
+@example
+$ guix build -K foo
+@dots{}
+$ cd /tmp/guix-build-foo.drv-0
+$ guix environment --no-grafts -C foo --ad-hoc strace gdb
+[env]# source ./environment-variables
+[env]# cd foo-1.2
+@end example
+
+Here, @command{guix environment -C} creates a container and spawns a new
+shell in it (@pxref{Aufruf von guix environment}).  The @command{--ad-hoc
+strace gdb} part adds the @command{strace} and @command{gdb} commands to the
+container, which would may find handy while debugging.  The
+@option{--no-grafts} option makes sure we get the exact same environment,
+with ungrafted packages (@pxref{Sicherheitsaktualisierungen}, for more info on grafts).
+
+To get closer to a container like that used by the build daemon, we can
+remove @file{/bin/sh}:
+
+@example
+[env]# rm /bin/sh
+@end example
+
+(Don't worry, this is harmless: this is all happening in the throw-away
+container created by @command{guix environment}.)
+
+The @command{strace} command is probably not in the search path, but we can
+run:
+
+@example
+[env]# $GUIX_ENVIRONMENT/bin/strace -f -o log make check
+@end example
+
+In this way, not only you will have reproduced the environment variables the
+daemon uses, you will also be running the build process in a container
+similar to the one the daemon uses.

+@cindex downloading package sources
+When writing a package definition, developers typically need to download a
+source tarball, compute its SHA256 hash, and write that hash in the package
+definition (@pxref{Pakete definieren}).  The @command{guix download} tool
+helps with this task: it downloads a file from the given URI, adds it to the
+store, and prints both its file name in the store and its SHA256 hash.
+
+The fact that the downloaded file is added to the store saves bandwidth:
+when the developer eventually tries to build the newly defined package with
+@command{guix build}, the source tarball will not have to be downloaded
+again because it is already in the store.  It is also a convenient way to
+temporarily stash files, which may be deleted eventually (@pxref{Aufruf von guix gc}).
+
+The @command{guix download} command supports the same URIs as used in
+package definitions.  In particular, it supports @code{mirror://} URIs.
+@code{https} URIs (HTTP over TLS) are supported @emph{provided} the Guile
+bindings for GnuTLS are available in the user's environment; when they are
+not available, an error is raised.  @xref{Guile Preparations, how to install
+the GnuTLS bindings for Guile,, gnutls-guile, GnuTLS-Guile}, for more

+
+@command{guix download} verifies HTTPS server certificates by loading the
+certificates of X.509 authorities from the directory pointed to by the
+@code{SSL_CERT_DIR} environment variable (@pxref{X.509-Zertifikate}),
+unless @option{--no-check-certificate} is used.

+The @command{guix hash} command computes the SHA256 hash of a file.  It is
+primarily a convenience tool for anyone contributing to the distribution: it
+computes the cryptographic hash of a file, which can be used in the
+definition of a package (@pxref{Pakete definieren}).
+
+The general syntax is:
+
+@example
+guix hash @var{option} @var{file}
+@end example
+
+When @var{file} is @code{-} (a hyphen), @command{guix hash} computes the
+hash of data read from standard input.  @command{guix hash} has the

+
+@table @code
+
+@item --format=@var{fmt}
+@itemx -f @var{fmt}
+Write the hash in the format specified by @var{fmt}.
+
+Supported formats: @code{nix-base32}, @code{base32}, @code{base16}
+(@code{hex} and @code{hexadecimal} can be used as well).
+
+If the @option{--format} option is not specified, @command{guix hash} will

+@itemx -r
+Compute the hash on @var{file} recursively.
+
+@c FIXME: Replace xref above with xref to an ``Archive'' section when

+In this case, the hash is computed on an archive containing @var{file},
+including its children if it is a directory.  Some of the metadata of
+@var{file} is part of the archive; for instance, when @var{file} is a

+The @command{guix import} command is useful for people who would like to add
+a package to the distribution with as little work as possible---a legitimate
+demand.  The command knows of a few repositories from which it can
+``import'' package metadata.  The result is a package definition, or a
+template thereof, in the format we know (@pxref{Pakete definieren}).
+
+The general syntax is:
+
+@example
+guix import @var{importer} @var{options}@dots{}
+@end example
+
+@var{importer} specifies the source from which to import package metadata,
+and @var{options} specifies a package identifier and other options specific
+to @var{importer}.  Currently, the available ``importers'' are:
+
+@table @code
+@item gnu
+Import metadata for the given GNU package.  This provides a template for the
+latest version of that GNU package, including the hash of its source
+tarball, and its canonical synopsis and description.
+
+Additional information such as the package dependencies and its license
+needs to be figured out manually.
+
+For example, the following command returns a package definition for
+GNU@tie{}Hello:
+

+Information is taken from the JSON-formatted description available at
+@code{rubygems.org} and includes most relevant information, including
+runtime dependencies.  There are some caveats, however.  The metadata
+doesn't distinguish between synopses and descriptions, so the same string is
+used for both fields.  Additionally, the details of non-Ruby dependencies
+required to build native extensions is unavailable and left as an exercise
+to the packager.

+
+Information is extracted from the @code{DESCRIPTION} file of the package.
+
+The command command below imports metadata for the @code{Cairo} R package:

+
+When @code{--archive=bioconductor} is added, metadata is imported from
+@uref{https://www.bioconductor.org/, Bioconductor}, a repository of R
+packages for for the analysis and comprehension of high-throughput genomic
+data in bioinformatics.
+
+Information is extracted from the @code{DESCRIPTION} file of a package

+Import metadata from @uref{http://www.ctan.org/, CTAN}, the comprehensive
+TeX archive network for TeX packages that are part of the
+@uref{https://www.tug.org/texlive/, TeX Live distribution}.
+
+Information about the package is obtained through the XML API provided by
+CTAN, while the source code is downloaded from the SVN repository of the Tex
+Live project.  This is done because the CTAN does not keep versioned
+archives.
+
+The command command below imports metadata for the @code{fontspec} TeX
+package:
+
+@example
+guix import texlive fontspec
+@end example
+
+When @code{--archive=DIRECTORY} is added, the source code is downloaded not
+from the @file{latex} sub-directory of the @file{texmf-dist/source} tree in
+the TeX Live SVN repository, but from the specified sibling directory under
+the same root.
+
+The command below imports metadata for the @code{ifxetex} package from CTAN
+while fetching the sources from the directory @file{texmf/source/generic}:
+
+@example
+guix import texlive --archive=generic ifxetex
+@end example
+
+@item json
+@cindex JSON, import
+Import package metadata from a local JSON file@footnote{This functionality
+requires Guile-JSON to be installed.  @xref{Voraussetzungen}.}.  Consider the
+following example package definition in JSON format:
+
+@example
+@{
+  "name": "hello",
+  "version": "2.10",
+  "source": "mirror://gnu/hello/hello-2.10.tar.gz",
+  "build-system": "gnu",
+  "home-page": "https://www.gnu.org/software/hello/",
+  "synopsis": "Hello, GNU world: An example GNU package",
+  "description": "GNU Hello prints a greeting.",
+  "license": "GPL-3.0+",
+  "native-inputs": ["gcc@@6"]
+@}
+@end example
+
+The field names are the same as for the @code{<package>} record
+(@xref{Pakete definieren}).  References to other packages are provided as
+JSON lists of quoted package specification strings such as @code{guile} or
+@code{guile@@2.0}.
+
+The importer also supports a more explicit source definition using the
+common fields for @code{<origin>} records:
+
+@example
+@{
+  @dots{}
+  "source": @{
+    "method": "url-fetch",
+    "uri": "mirror://gnu/hello/hello-2.10.tar.gz",
+    "sha256": @{
+      "base32": "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"
+    @}
+  @}
+  @dots{}
+@}
+@end example
+
+The command below reads metadata from the JSON file @code{hello.json} and
+outputs a package expression:
+
+@example
+guix import json hello.json
+@end example
+
+@item nix
+Import metadata from a local copy of the source of the
+@uref{http://nixos.org/nixpkgs/, Nixpkgs distribution}@footnote{This relies
+on the @command{nix-instantiate} command of @uref{http://nixos.org/nix/,
+Nix}.}.  Package definitions in Nixpkgs are typically written in a mixture
+of Nix-language and Bash code.  This command only imports the high-level
+package structure that is written in the Nix language.  It normally includes
+all the basic fields of a package definition.
+
+When importing a GNU package, the synopsis and descriptions are replaced by
+their canonical upstream variant.
+
+Usually, you will first need to do:
+
+@example
+export NIX_REMOTE=daemon
+@end example
+
+@noindent
+so that @command{nix-instantiate} does not try to open the Nix database.
+
+As an example, the command below imports the package definition of
+LibreOffice (more precisely, it imports the definition of the package bound
+to the @code{libreoffice} top-level attribute):
+
+@example
+guix import nix ~/path/to/nixpkgs libreoffice
+@end example
+
+@item hackage
+@cindex hackage
+Import metadata from the Haskell community's central package archive
+@uref{https://hackage.haskell.org/, Hackage}.  Information is taken from
+Cabal files and includes all the relevant information, including package
+dependencies.
+
+Specific command-line options are:
+
+@table @code
+@item --stdin
+@itemx -s
+Read a Cabal file from standard input.
+@item --no-test-dependencies
+@itemx -t
+Do not include dependencies required only by the test suites.
+@item --cabal-environment=@var{alist}
+@itemx -e @var{alist}
+@var{alist} is a Scheme alist defining the environment in which the Cabal
+conditionals are evaluated.  The accepted keys are: @code{os}, @code{arch},
+@code{impl} and a string representing the name of a flag.  The value
+associated with a flag has to be either the symbol @code{true} or
+@code{false}.  The value associated with other keys has to conform to the
+Cabal file format definition.  The default value associated with the keys
+@code{os}, @code{arch} and @code{impl} is @samp{linux}, @samp{x86_64} and
+@samp{ghc}, respectively.
+@item --recursive
+@itemx -r
+Traverse the dependency graph of the given upstream package recursively and
+generate package expressions for all those packages that are not yet in
+Guix.
+@end table
+
+The command below imports metadata for the latest version of the @code{HTTP}
+Haskell package without including test dependencies and specifying the value
+of the flag @samp{network-uri} as @code{false}:
+
+@example
+guix import hackage -t -e "'((\"network-uri\" . false))" HTTP
+@end example
+
+A specific package version may optionally be specified by following the
+package name by an at-sign and a version number as in the following example:
+
+@example
+guix import hackage mtl@@2.1.3.1
+@end example
+
+@item stackage
+@cindex stackage
+The @code{stackage} importer is a wrapper around the @code{hackage} one.  It
+takes a package name, looks up the package version included in a long-term
+support (LTS) @uref{https://www.stackage.org, Stackage} release and uses the
+@code{hackage} importer to retrieve its metadata.  Note that it is up to you
+to select an LTS release compatible with the GHC compiler used by Guix.
+
+Specific command-line options are:
+
+@table @code
+@item --no-test-dependencies
+@itemx -t
+Do not include dependencies required only by the test suites.
+@item --lts-version=@var{version}
+@itemx -l @var{version}
+@var{version} is the desired LTS release version.  If omitted the latest
+release is used.
+@item --recursive
+@itemx -r
+Traverse the dependency graph of the given upstream package recursively and
+generate package expressions for all those packages that are not yet in
+Guix.
+@end table
+
+The command below imports metadata for the @code{HTTP} Haskell package

+
+@node Aufruf von guix refresh
+@section Invoking @command{guix refresh}
+
+@cindex @command{guix refresh}
+The primary audience of the @command{guix refresh} command is developers of
+the GNU software distribution.  By default, it reports any packages provided
+by the distribution that are outdated compared to the latest upstream
+version, like this:
+
+@example
+$ guix refresh
+gnu/packages/gettext.scm:29:13: gettext would be upgraded from 0.18.1.1 to 0.18.2.1
+gnu/packages/glib.scm:77:12: glib would be upgraded from 2.34.3 to 2.37.0
+@end example
+
+Alternately, one can specify packages to consider, in which case a warning
+is emitted for packages that lack an updater:
+
+@example
+$ guix refresh coreutils guile guile-ssh
+gnu/packages/ssh.scm:205:2: warning: no updater for guile-ssh
+gnu/packages/guile.scm:136:12: guile would be upgraded from 2.0.12 to 2.0.13
+@end example
+
+@command{guix refresh} browses the upstream repository of each package and
+determines the highest version number of the releases therein.  The command
+knows how to update specific types of packages: GNU packages, ELPA packages,
+etc.---see the documentation for @option{--type} below.  There are many
+packages, though, for which it lacks a method to determine whether a new
+upstream release is available.  However, the mechanism is extensible, so
+feel free to get in touch with us to add a new method!
+
+Sometimes the upstream name differs from the package name used in Guix, and
+@command{guix refresh} needs a little help.  Most updaters honor the
+@code{upstream-name} property in package definitions, which can be used to
+that effect:
+
+@example
+(define-public network-manager
+  (package
+    (name "network-manager")
+    ;; @dots{}
+    (properties '((upstream-name . "NetworkManager")))))
+@end example
+
+When passed @code{--update}, it modifies distribution source files to update
+the version numbers and source tarball hashes of those package recipes
+(@pxref{Pakete definieren}).  This is achieved by downloading each package's
+latest source tarball and its associated OpenPGP signature, authenticating
+the downloaded tarball against its signature using @command{gpg}, and
+finally computing its hash.  When the public key used to sign the tarball is
+missing from the user's keyring, an attempt is made to automatically
+retrieve it from a public key server; when this is successful, the key is
+added to the user's keyring; otherwise, @command{guix refresh} reports an
+error.
+
+The following options are supported:
+
+@table @code
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Consider the package @var{expr} evaluates to.
+
+This is useful to precisely refer to a package, as in this example:
+
+@example
+guix refresh -l -e '(@@@@ (gnu packages commencement) glibc-final)'
+@end example
+
+This command lists the dependents of the ``final'' libc (essentially all the
+packages.)
+
+@item --update
+@itemx -u
+Update distribution source files (package recipes) in place.  This is
+usually run from a checkout of the Guix source tree (@pxref{Guix vor der Installation ausführen}):
+
+@example
+$ ./pre-inst-env guix refresh -s non-core -u
+@end example
+
+@xref{Pakete definieren}, for more information on package definitions.
+
+@item --select=[@var{subset}]
+@itemx -s @var{subset}
+Select all the packages in @var{subset}, one of @code{core} or
+@code{non-core}.
+
+The @code{core} subset refers to all the packages at the core of the
+distribution---i.e., packages that are used to build ``everything else''.
+This includes GCC, libc, Binutils, Bash, etc.  Usually, changing one of
+these packages in the distribution entails a rebuild of all the others.
+Thus, such updates are an inconvenience to users in terms of build time or
+bandwidth used to achieve the upgrade.
+
+The @code{non-core} subset refers to the remaining packages.  It is
+typically useful in cases where an update of the core packages would be
+inconvenient.
+
+@item --manifest=@var{Datei}
+@itemx -m @var{Datei}
+Select all the packages from the manifest in @var{file}. This is useful to
+check if any packages of the user manifest can be updated.
+
+@item --type=@var{updater}
+@itemx -t @var{updater}
+Select only packages handled by @var{updater} (may be a comma-separated list
+of updaters).  Currently, @var{updater} may be one of:
+
+@table @code
+@item gnu
+the updater for GNU packages;
+@item gnome
+the updater for GNOME packages;
+@item kde
+the updater for KDE packages;
+@item xorg
+the updater for X.org packages;
+@item kernel.org
+the updater for packages hosted on kernel.org;
+@item elpa
+the updater for @uref{http://elpa.gnu.org/, ELPA} packages;
+@item cran
+the updater for @uref{https://cran.r-project.org/, CRAN} packages;
+@item bioconductor
+the updater for @uref{https://www.bioconductor.org/, Bioconductor} R
+packages;
+@item cpan
+the updater for @uref{http://www.cpan.org/, CPAN} packages;
+@item pypi
+the updater for @uref{https://pypi.python.org, PyPI} packages.
+@item gem
+the updater for @uref{https://rubygems.org, RubyGems} packages.
+@item github
+the updater for @uref{https://github.com, GitHub} packages.
+@item hackage
+the updater for @uref{https://hackage.haskell.org, Hackage} packages.
+@item stackage
+the updater for @uref{https://www.stackage.org, Stackage} packages.
+@item crate
+the updater for @uref{https://crates.io, Crates} packages.
+@end table
+
+For instance, the following command only checks for updates of Emacs
+packages hosted at @code{elpa.gnu.org} and for updates of CRAN packages:
+
+@example
+$ guix refresh --type=elpa,cran
+gnu/packages/statistics.scm:819:13: r-testthat would be upgraded from 0.10.0 to 0.11.0
+gnu/packages/emacs.scm:856:13: emacs-auctex would be upgraded from 11.88.6 to 11.88.9
+@end example
+
+@end table
+
+In addition, @command{guix refresh} can be passed one or more package names,
+as in this example:
+
+@example
+$ ./pre-inst-env guix refresh -u emacs idutils gcc@@4.8
+@end example
+
+@noindent
+The command above specifically updates the @code{emacs} and @code{idutils}
+packages.  The @code{--select} option would have no effect in this case.
+
+When considering whether to upgrade a package, it is sometimes convenient to
+know which packages would be affected by the upgrade and should be checked
+for compatibility.  For this the following option may be used when passing
+@command{guix refresh} one or more package names:
+
+@table @code
+
+@item --list-updaters
+@itemx -L
+List available updaters and exit (see @option{--type} above.)
+
+For each updater, display the fraction of packages it covers; at the end,
+display the fraction of packages covered by all these updaters.
+
+@item --list-dependent
+@itemx -l
+List top-level dependent packages that would need to be rebuilt as a result
+of upgrading one or more packages.
+
+@xref{Aufruf von guix graph, the @code{reverse-package} type of @command{guix
+graph}}, for information on how to visualize the list of dependents of a
+package.
+
+@end table
+
+Be aware that the @code{--list-dependent} option only @emph{approximates}
+the rebuilds that would be required as a result of an upgrade.  More
+rebuilds might be required under some circumstances.
+
+@example
+$ guix refresh --list-dependent flex
+Building the following 120 packages would ensure 213 dependent packages are rebuilt:
+hop@@2.4.0 geiser@@0.4 notmuch@@0.18 mu@@0.9.9.5 cflow@@1.4 idutils@@4.6 @dots{}
+@end example
+
+The command above lists a set of packages that could be built to check for
+compatibility with an upgraded @code{flex} package.
+
+The following options can be used to customize GnuPG operation:
+
+@table @code
+
+@item --gpg=@var{command}
+Use @var{command} as the GnuPG 2.x command.  @var{command} is searched for
+in @code{$PATH}.
+
+@item --keyring=@var{file}
+Use @var{file} as the keyring for upstream keys.  @var{file} must be in the
+@dfn{keybox format}.  Keybox files usually have a name ending in @file{.kbx}
+and the GNU@tie{}Privacy Guard (GPG) can manipulate these files
+(@pxref{kbxutil, @command{kbxutil},, gnupg, Using the GNU Privacy Guard},
+for information on a tool to manipulate keybox files).
+
+When this option is omitted, @command{guix refresh} uses
+@file{~/.config/guix/upstream/trustedkeys.kbx} as the keyring for upstream
+signing keys.  OpenPGP signatures are checked against keys from this
+keyring; missing keys are downloaded to this keyring as well (see
+@option{--key-download} below.)
+
+You can export keys from your default GPG keyring into a keybox file using
+commands like this one:
+
+@example
+gpg --export rms@@gnu.org | kbxutil --import-openpgp >> mykeyring.kbx
+@end example
+
+Likewise, you can fetch keys to a specific keybox file like this:
+
+@example
+gpg --no-default-keyring --keyring mykeyring.kbx \
+  --recv-keys @value{OPENPGP-SIGNING-KEY-ID}
+@end example
+
+@ref{GPG Configuration Options, @option{--keyring},, gnupg, Using the GNU
+Privacy Guard}, for more information on GPG's @option{--keyring} option.
+
+@item --key-download=@var{policy}
+Handle missing OpenPGP keys according to @var{policy}, which may be one of:
+
+@table @code
+@item always
+Always download missing OpenPGP keys from the key server, and add them to
+the user's GnuPG keyring.
+
+@item never
+Never try to download missing OpenPGP keys.  Instead just bail out.
+
+@item interactive
+When a package signed with an unknown OpenPGP key is encountered, ask the
+user whether to download it or not.  This is the default behavior.
+@end table
+
+@item --key-server=@var{host}
+Use @var{host} as the OpenPGP key server when importing a public key.
+
+@end table
+
+The @code{github} updater uses the @uref{https://developer.github.com/v3/,
+GitHub API} to query for new releases.  When used repeatedly e.g.@: when
+refreshing all packages, GitHub will eventually refuse to answer any further
+API requests.  By default 60 API requests per hour are allowed, and a full
+refresh on all GitHub packages in Guix requires more than this.
+Authentication with GitHub through the use of an API token alleviates these
+limits.  To use an API token, set the environment variable
+@code{GUIX_GITHUB_TOKEN} to a token procured from
+@uref{https://github.com/settings/tokens} or otherwise.

+@cindex @command{guix size}
+The @command{guix size} command helps package developers profile the disk
+usage of packages.  It is easy to overlook the impact of an additional
+dependency added to a package, or the impact of using a single output for a
+package that could easily be split (@pxref{Pakete mit mehreren Ausgaben.}).  Such are the typical issues that @command{guix size} can
+highlight.
+
+The command can be passed one or more package specifications such as
+@code{gcc@@4.8} or @code{guile:debug}, or a file name in the store.
+Consider this example:
+
+@example
+$ guix size coreutils
+store item                               total    self
+/gnu/store/@dots{}-gcc-5.5.0-lib           60.4    30.1  38.1%

+/gnu/store/@dots{}-bash-static-4.4.12       1.5     1.5   1.9%
+/gnu/store/@dots{}-acl-2.2.52              61.1     0.4   0.5%
+/gnu/store/@dots{}-attr-2.4.47             60.6     0.2   0.3%
+/gnu/store/@dots{}-libcap-2.25             60.5     0.2   0.2%
+total: 78.9 MiB
+@end example
+
+@cindex Abschluss
+The store items listed here constitute the @dfn{transitive closure} of
+Coreutils---i.e., Coreutils and all its dependencies, recursively---as would
+be returned by:
+
+@example
+$ guix gc -R /gnu/store/@dots{}-coreutils-8.23
+@end example
+
+Here the output shows three columns next to store items.  The first column,
+labeled ``total'', shows the size in mebibytes (MiB) of the closure of the
+store item---that is, its own size plus the size of all its dependencies.
+The next column, labeled ``self'', shows the size of the item itself.  The
+last column shows the ratio of the size of the item itself to the space
+occupied by all the items listed here.
+
+In this example, we see that the closure of Coreutils weighs in at
+79@tie{}MiB, most of which is taken by libc and GCC's run-time support
+libraries.  (That libc and GCC's libraries represent a large fraction of the
+closure is not a problem @i{per se} because they are always available on the
+system anyway.)
+
+When the package(s) passed to @command{guix size} are available in the
+store@footnote{More precisely, @command{guix size} looks for the
+@emph{ungrafted} variant of the given package(s), as returned by @code{guix
+build @var{package} --no-grafts}.  @xref{Sicherheitsaktualisierungen}, for information
+on grafts.}, @command{guix size} queries the daemon to determine its
+dependencies, and measures its size in the store, similar to @command{du -ms
+--apparent-size} (@pxref{du invocation,,, coreutils, GNU Coreutils}).
+
+When the given packages are @emph{not} in the store, @command{guix size}
+reports information based on the available substitutes
+(@pxref{Substitute}).  This makes it possible it to profile disk usage of
+store items that are not even on disk, only available remotely.
+
+You can also specify several package names:
+
+@example
+$ guix size coreutils grep sed bash
+store item                               total    self
+/gnu/store/@dots{}-coreutils-8.24          77.8    13.8  13.4%
+/gnu/store/@dots{}-grep-2.22               73.1     0.8   0.8%
+/gnu/store/@dots{}-bash-4.3.42             72.3     4.7   4.6%
+/gnu/store/@dots{}-readline-6.3            67.6     1.2   1.2%
+@dots{}
+total: 102.3 MiB
+@end example
+
+@noindent
+In this example we see that the combination of the four packages takes
+102.3@tie{}MiB in total, which is much less than the sum of each closure
+since they have a lot of dependencies in common.
+
+The available options are:
+
+@table @option
+
+@item --substitute-urls=@var{URLs}
+Use substitute information from @var{urls}.  @xref{client-substitute-urls,
+the same option for @code{guix build}}.
+
+@item --sort=@var{key}
+Sort lines according to @var{key}, one of the following options:
+
+@table @code
+@item self
+the size of each item (the default);
+@item Abschluss
+the total size of the item's closure.
+@end table
+
+@item --map-file=@var{file}
+Write a graphical map of disk usage in PNG format to @var{file}.
+
+For the example above, the map looks like this:
+
+@image{images/coreutils-size-map,5in,, map of Coreutils disk usage produced
+by @command{guix size}}
+
+This option requires that
+@uref{http://wingolog.org/software/guile-charting/, Guile-Charting} be
+installed and visible in Guile's module search path.  When that is not the
+case, @command{guix size} fails as it tries to load it.

+@cindex DAG
+@cindex @command{guix graph}
+@cindex Paketabhängigkeiten
+Packages and their dependencies form a @dfn{graph}, specifically a directed
+acyclic graph (DAG).  It can quickly become difficult to have a mental model
+of the package DAG, so the @command{guix graph} command provides a visual
+representation of the DAG.  By default, @command{guix graph} emits a DAG
+representation in the input format of @uref{http://www.graphviz.org/,
+Graphviz}, so its output can be passed directly to the @command{dot} command
+of Graphviz.  It can also emit an HTML page with embedded JavaScript code to
+display a ``chord diagram'' in a Web browser, using the
+@uref{https://d3js.org/, d3.js} library, or emit Cypher queries to construct
+a graph in a graph database supporting the @uref{http://www.opencypher.org/,
+openCypher} query language.  The general syntax is:
+
+@example
+guix graph @var{options} @var{package}@dots{}
+@end example
+
+For example, the following command generates a PDF file representing the
+package DAG for the GNU@tie{}Core Utilities, showing its build-time
+dependencies:
+
+@example
+guix graph coreutils | dot -Tpdf > dag.pdf
+@end example
+
+The output looks like this:
+
+@image{images/coreutils-graph,2in,,Dependency graph of the GNU Coreutils}
+
+Nice little graph, no?
+
+But there is more than one graph! The one above is concise: it is the graph
+of package objects, omitting implicit inputs such as GCC, libc, grep, etc.
+It is often useful to have such a concise graph, but sometimes one may want
+to see more details.  @command{guix graph} supports several types of graphs,
+allowing you to choose the level of detail:
+
+@table @code
+@item package
+This is the default type used in the example above.  It shows the DAG of
+package objects, excluding implicit dependencies.  It is concise, but
+filters out many details.
+
+@item reverse-package
+This shows the @emph{reverse} DAG of packages.  For example:
+
+@example
+guix graph --type=reverse-package ocaml
+@end example
+
+...@: yields the graph of packages that depend on OCaml.
+
+Note that for core packages this can yield huge graphs.  If all you want is
+to know the number of packages that depend on a given package, use
+@command{guix refresh --list-dependent} (@pxref{Aufruf von guix refresh,
+@option{--list-dependent}}).
+
+@item bag-emerged
+This is the package DAG, @emph{including} implicit inputs.
+
+For instance, the following command:
+
+@example
+guix graph --type=bag-emerged coreutils | dot -Tpdf > dag.pdf
+@end example
+
+...@: yields this bigger graph:
+
+@image{images/coreutils-bag-graph,,5in,Detailed dependency graph of the GNU
+Coreutils}
+
+At the bottom of the graph, we see all the implicit inputs of
+@var{gnu-build-system} (@pxref{Erstellungssysteme, @code{gnu-build-system}}).
+
+Now, note that the dependencies of these implicit inputs---that is, the
+@dfn{bootstrap dependencies} (@pxref{Bootstrapping})---are not shown here,
+for conciseness.
+
+@item bag
+Similar to @code{bag-emerged}, but this time including all the bootstrap
+dependencies.
+
+@item bag-with-origins
+Similar to @code{bag}, but also showing origins and their dependencies.
+
+@item Ableitung
+This is the most detailed representation: It shows the DAG of derivations
+(@pxref{Ableitungen}) and plain store items.  Compared to the above
+representation, many additional nodes are visible, including build scripts,
+patches, Guile modules, etc.
+
+For this type of graph, it is also possible to pass a @file{.drv} file name
+instead of a package name, as in:
+
+@example
+guix graph -t derivation `guix system build -d my-config.scm`
+@end example
+
+@item module
+This is the graph of @dfn{package modules} (@pxref{Paketmodule}).  For
+example, the following command shows the graph for the package module that
+defines the @code{guile} package:
+
+@example
+guix graph -t module guile | dot -Tpdf > module-graph.pdf
+@end example
+@end table
+
+All the types above correspond to @emph{build-time dependencies}.  The
+following graph type represents the @emph{run-time dependencies}:
+
+@table @code
+@item references
+This is the graph of @dfn{references} of a package output, as returned by
+@command{guix gc --references} (@pxref{Aufruf von guix gc}).
+
+If the given package output is not available in the store, @command{guix
+graph} attempts to obtain dependency information from substitutes.
+
+Here you can also pass a store file name instead of a package name.  For
+example, the command below produces the reference graph of your profile
+(which can be big!):
+
+@example
+guix graph -t references `readlink -f ~/.guix-profile`
+@end example
+
+@item referrers
+This is the graph of the @dfn{referrers} of a store item, as returned by
+@command{guix gc --referrers} (@pxref{Aufruf von guix gc}).
+
+This relies exclusively on local information from your store.  For instance,
+let us suppose that the current Inkscape is available in 10 profiles on your
+machine; @command{guix graph -t referrers inkscape} will show a graph rooted
+at Inkscape and with those 10 profiles linked to it.
+
+It can help determine what is preventing a store item from being garbage
+collected.
+
+@end table
+
+The available options are the following:
+
+@table @option
+@item --type=@var{type}
+@itemx -t @var{type}
+Produce a graph output of @var{type}, where @var{type} must be one of the
+values listed above.
+
+@item --list-types
+List the supported graph types.
+
+@item --backend=@var{backend}
+@itemx -b @var{backend}
+Produce a graph using the selected @var{backend}.
+
+@item --list-backends
+List the supported graph backends.
+
+Currently, the available backends are Graphviz and d3.js.
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Consider the package @var{expr} evaluates to.
+
+This is useful to precisely refer to a package, as in this example:
+
+@example
+guix graph -e '(@@@@ (gnu packages commencement) gnu-make-final)'
+@end example
+
+@item --system=@var{System}
+@itemx -s @var{system}
+Display the graph for @var{system}---e.g., @code{i686-linux}.
+
+The package dependency graph is largely architecture-independent, but there
+are some architecture-dependent bits that this option allows you to
+visualize.

+@cindex reproducible build environments

+@cindex @command{guix environment}
+@cindex environment, package build environment
+The purpose of @command{guix environment} is to assist hackers in creating
+reproducible development environments without polluting their package
+profile.  The @command{guix environment} tool takes one or more packages,
+builds all of their inputs, and creates a shell environment to use them.
+
+The general syntax is:
+
+@example
+guix environment @var{options} @var{package}@dots{}
+@end example
+
+The following example spawns a new shell set up for the development of
+GNU@tie{}Guile:
+
+@example
+guix environment guile
+@end example
+
+If the needed dependencies are not built yet, @command{guix environment}
+automatically builds them.  The environment of the new shell is an augmented
+version of the environment that @command{guix environment} was run in.  It
+contains the necessary search paths for building the given package added to
+the existing environment variables.  To create a ``pure'' environment, in
+which the original environment variables have been unset, use the
+@code{--pure} option@footnote{Users sometimes wrongfully augment environment
+variables such as @code{PATH} in their @file{~/.bashrc} file.  As a
+consequence, when @code{guix environment} launches it, Bash may read
+@file{~/.bashrc}, thereby introducing ``impurities'' in these environment
+variables.  It is an error to define such environment variables in
+@file{.bashrc}; instead, they should be defined in @file{.bash_profile},
+which is sourced only by log-in shells.  @xref{Bash Startup Files,,, bash,
+The GNU Bash Reference Manual}, for details on Bash start-up files.}.
+
+@vindex GUIX_ENVIRONMENT
+@command{guix environment} defines the @code{GUIX_ENVIRONMENT} variable in
+the shell it spawns; its value is the file name of the profile of this
+environment.  This allows users to, say, define a specific prompt for
+development environments in their @file{.bashrc} (@pxref{Bash Startup
+Files,,, bash, The GNU Bash Reference Manual}):
+
+@example
+if [ -n "$GUIX_ENVIRONMENT" ]
+then
+    export PS1="\u@@\h \w [dev]\$ "
+fi
+@end example
+
+@noindent
+...@: or to browse the profile:
+
+@example
+$ ls "$GUIX_ENVIRONMENT/bin"
+@end example
+
+Additionally, more than one package may be specified, in which case the
+union of the inputs for the given packages are used.  For example, the
+command below spawns a shell where all of the dependencies of both Guile and
+Emacs are available:
+
+@example
+guix environment guile emacs
+@end example
+
+Sometimes an interactive shell session is not desired.  An arbitrary command
+may be invoked by placing the @code{--} token to separate the command from
+the rest of the arguments:
+
+@example
+guix environment guile -- make -j4
+@end example
+
+In other situations, it is more convenient to specify the list of packages
+needed in the environment.  For example, the following command runs
+@command{python} from an environment containing Python@tie{}2.7 and NumPy:
+
+@example
+guix environment --ad-hoc python2-numpy python-2.7 -- python
+@end example
+
+Furthermore, one might want the dependencies of a package and also some
+additional packages that are not build-time or runtime dependencies, but are
+useful when developing nonetheless.  Because of this, the @code{--ad-hoc}
+flag is positional.  Packages appearing before @code{--ad-hoc} are
+interpreted as packages whose dependencies will be added to the
+environment.  Packages appearing after are interpreted as packages that will
+be added to the environment directly.  For example, the following command
+creates a Guix development environment that additionally includes Git and
+strace:
+
+@example
+guix environment guix --ad-hoc git strace
+@end example
+
+Sometimes it is desirable to isolate the environment as much as possible,
+for maximal purity and reproducibility.  In particular, when using Guix on a
+host distro that is not GuixSD, it is desirable to prevent access to
+@file{/usr/bin} and other system-wide resources from the development
+environment.  For example, the following command spawns a Guile REPL in a
+``container'' where only the store and the current working directory are
+mounted:
+
+@example
+guix environment --ad-hoc --container guile -- guile
+@end example
+
+@quotation Anmerkung
+The @code{--container} option requires Linux-libre 3.19 or newer.
+@end quotation
+
+The available options are summarized below.
+
+@table @code
+@item --root=@var{file}
+@itemx -r @var{file}
+@cindex persistent environment
+@cindex garbage collector root, for environments
+Make @var{file} a symlink to the profile for this environment, and register
+it as a garbage collector root.
+
+This is useful if you want to protect your environment from garbage
+collection, to make it ``persistent''.
+
+When this option is omitted, the environment is protected from garbage
+collection only for the duration of the @command{guix environment} session.
+This means that next time you recreate the same environment, you could have
+to rebuild or re-download packages.  @xref{Aufruf von guix gc}, for more on GC
+roots.
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Create an environment for the package or list of packages that @var{expr}
+evaluates to.
+
+For example, running:
+
+@example
+guix environment -e '(@@ (gnu packages maths) petsc-openmpi)'
+@end example
+
+starts a shell with the environment for this specific variant of the PETSc
+package.
+
+Running:
+
+@example
+guix environment --ad-hoc -e '(@@ (gnu) %base-packages)'
+@end example
+
+starts a shell with all the GuixSD base packages available.
+
+The above commands only use the default output of the given packages.  To
+select other outputs, two element tuples can be specified:
+
+@example
+guix environment --ad-hoc -e '(list (@@ (gnu packages bash) bash) "include")'
+@end example
+
+@item --load=@var{file}
+@itemx -l @var{file}
+Create an environment for the package or list of packages that the code
+within @var{file} evaluates to.
+
+Zum Beispiel könnte die @var{Datei} eine Definition wie diese enthalten
+(@pxref{Pakete definieren}):
+
+@example
+@verbatiminclude environment-gdb.scm
+@end example
+
+@item --manifest=@var{Datei}
+@itemx -m @var{Datei}
+Create an environment for the packages contained in the manifest object
+returned by the Scheme code in @var{file}.
+
+This is similar to the same-named option in @command{guix package}
+(@pxref{profile-manifest, @option{--manifest}}) and uses the same manifest
+files.
+
+@item --ad-hoc
+Include all specified packages in the resulting environment, as if an @i{ad
+hoc} package were defined with them as inputs.  This option is useful for
+quickly creating an environment without having to write a package expression
+to contain the desired inputs.
+
+For instance, the command:
+
+@example
+guix environment --ad-hoc guile guile-sdl -- guile
+@end example
+
+runs @command{guile} in an environment where Guile and Guile-SDL are
+available.
+
+Note that this example implicitly asks for the default output of
+@code{guile} and @code{guile-sdl}, but it is possible to ask for a specific
+output---e.g., @code{glib:bin} asks for the @code{bin} output of @code{glib}
+(@pxref{Pakete mit mehreren Ausgaben.}).
+
+This option may be composed with the default behavior of @command{guix
+environment}.  Packages appearing before @code{--ad-hoc} are interpreted as
+packages whose dependencies will be added to the environment, the default
+behavior.  Packages appearing after are interpreted as packages that will be
+added to the environment directly.
+
+@item --pure
+Unset existing environment variables when building the new environment.
+This has the effect of creating an environment in which search paths only
+contain package inputs.
+
+@item --search-paths
+Display the environment variable definitions that make up the environment.
+
+@item --system=@var{System}
+@itemx -s @var{system}
+Attempt to build for @var{system}---e.g., @code{i686-linux}.
+
+@item --container
+@itemx -C
+@cindex container
+Run @var{command} within an isolated container.  The current working
+directory outside the container is mapped inside the container.
+Additionally, unless overridden with @code{--user}, a dummy home directory
+is created that matches the current user's home directory, and
+@file{/etc/passwd} is configured accordingly.  The spawned process runs as
+the current user outside the container, but has root privileges in the
+context of the container.
+
+@item --network
+@itemx -N
+For containers, share the network namespace with the host system.
+Containers created without this flag only have access to the loopback
+device.
+
+@item --link-profile
+@itemx -P
+For containers, link the environment profile to @file{~/.guix-profile}
+within the container.  This is equivalent to running the command @command{ln
+-s $GUIX_ENVIRONMENT ~/.guix-profile} within the container.  Linking will
+fail and abort the environment if the directory already exists, which will
+certainly be the case if @command{guix environment} was invoked in the
+user's home directory.
+
+Certain packages are configured to look in @code{~/.guix-profile} for
+configuration files and data;@footnote{For example, the @code{fontconfig}
+package inspects @file{~/.guix-profile/share/fonts} for additional fonts.}
+@code{--link-profile} allows these programs to behave as expected within the
+environment.
+
+@item --user=@var{user}
+@itemx -u @var{user}
+For containers, use the username @var{user} in place of the current user.
+The generated @file{/etc/passwd} entry within the container will contain the
+name @var{user}; the home directory will be @file{/home/USER}; and no user
+GECOS data will be copied.  @var{user} need not exist on the system.
+
+Additionally, any shared or exposed path (see @code{--share} and
+@code{--expose} respectively) whose target is within the current user's home
+directory will be remapped relative to @file{/home/USER}; this includes the
+automatic mapping of the current working directory.
+
+@example
+# will expose paths as /home/foo/wd, /home/foo/test, and /home/foo/target
+cd $HOME/wd
+guix environment --container --user=foo \
+     --expose=$HOME/test \
+     --expose=/tmp/target=$HOME/target
+@end example
+
+While this will limit the leaking of user identity through home paths and
+each of the user fields, this is only one useful component of a broader
+privacy/anonymity solution---not one in and of itself.
+
+@item --expose=@var{source}[=@var{target}]
+For containers, expose the file system @var{source} from the host system as
+the read-only file system @var{target} within the container.  If
+@var{target} is not specified, @var{source} is used as the target mount
+point in the container.
+
+The example below spawns a Guile REPL in a container in which the user's
+home directory is accessible read-only via the @file{/exchange} directory:
+
+@example
+guix environment --container --expose=$HOME=/exchange --ad-hoc guile -- guile
+@end example
+
+@item --share=@var{source}[=@var{target}]
+For containers, share the file system @var{source} from the host system as
+the writable file system @var{target} within the container.  If @var{target}
+is not specified, @var{source} is used as the target mount point in the
+container.
+
+The example below spawns a Guile REPL in a container in which the user's
+home directory is accessible for both reading and writing via the
+@file{/exchange} directory:
+
+@example
+guix environment --container --share=$HOME=/exchange --ad-hoc guile -- guile
+@end example
+@end table
+
+@command{guix environment} also supports all of the common build options
+that @command{guix build} supports (@pxref{Gemeinsame Erstellungsoptionen}).
+
+
+@node Aufruf von guix publish
+@section Invoking @command{guix publish}
+
+@cindex @command{guix publish}
+The purpose of @command{guix publish} is to enable users to easily share
+their store with others, who can then use it as a substitute server
+(@pxref{Substitute}).
+
+When @command{guix publish} runs, it spawns an HTTP server which allows
+anyone with network access to obtain substitutes from it.  This means that
+any machine running Guix can also act as if it were a build farm, since the
+HTTP interface is compatible with Hydra, the software behind the
+@code{hydra.gnu.org} build farm.
+
+For security, each substitute is signed, allowing recipients to check their
+authenticity and integrity (@pxref{Substitute}).  Because @command{guix
+publish} uses the signing key of the system, which is only readable by the
+system administrator, it must be started as root; the @code{--user} option
+makes it drop root privileges early on.
+
+The signing key pair must be generated before @command{guix publish} is
+launched, using @command{guix archive --generate-key} (@pxref{Aufruf von guix archive}).
+
+The general syntax is:
+
+@example
+guix publish @var{options}@dots{}
+@end example
+
+Running @command{guix publish} without any additional arguments will spawn
+an HTTP server on port 8080:
+
+@example
+guix publish
+@end example
+
+Once a publishing server has been authorized (@pxref{Aufruf von guix archive}), the daemon may download substitutes from it:
+
+@example
+guix-daemon --substitute-urls=http://example.org:8080
+@end example
+
+By default, @command{guix publish} compresses archives on the fly as it
+serves them.  This ``on-the-fly'' mode is convenient in that it requires no
+setup and is immediately available.  However, when serving lots of clients,
+we recommend using the @option{--cache} option, which enables caching of the
+archives before they are sent to clients---see below for details.  The
+@command{guix weather} command provides a handy way to check what a server
+provides (@pxref{Aufruf von guix weather}).
+
+As a bonus, @command{guix publish} also serves as a content-addressed mirror
+for source files referenced in @code{origin} records (@pxref{„origin“-Referenz}).  For instance, assuming @command{guix publish} is running on
+@code{example.org}, the following URL returns the raw
+@file{hello-2.10.tar.gz} file with the given SHA256 hash (represented in
+@code{nix-base32} format, @pxref{Aufruf von guix hash}):
+
+@example
+http://example.org/file/hello-2.10.tar.gz/sha256/0ssi1@dots{}ndq1i
+@end example
+
+Obviously, these URLs only work for files that are in the store; in other
+cases, they return 404 (``Not Found'').
+
+@cindex build logs, publication
+Build logs are available from @code{/log} URLs like:
+
+@example
+http://example.org/log/gwspk@dots{}-guile-2.2.3
+@end example
+
+@noindent
+When @command{guix-daemon} is configured to save compressed build logs, as
+is the case by default (@pxref{Aufruf des guix-daemon}), @code{/log} URLs
+return the compressed log as-is, with an appropriate @code{Content-Type}
+and/or @code{Content-Encoding} header.  We recommend running
+@command{guix-daemon} with @code{--log-compression=gzip} since Web browsers
+can automatically decompress it, which is not the case with bzip2
+compression.
+
+The following options are available:
+
+@table @code
+@item --port=@var{port}
+@itemx -p @var{port}
+Listen for HTTP requests on @var{port}.
+
+@item --listen=@var{host}
+Listen on the network interface for @var{host}.  The default is to accept
+connections from any interface.
+
+@item --user=@var{user}
+@itemx -u @var{user}
+Change privileges to @var{user} as soon as possible---i.e., once the server
+socket is open and the signing key has been read.
+
+@item --compression[=@var{level}]
+@itemx -C [@var{level}]
+Compress data using the given @var{level}.  When @var{level} is zero,
+disable compression.  The range 1 to 9 corresponds to different gzip
+compression levels: 1 is the fastest, and 9 is the best (CPU-intensive).
+The default is 3.
+
+Unless @option{--cache} is used, compression occurs on the fly and the
+compressed streams are not cached.  Thus, to reduce load on the machine that
+runs @command{guix publish}, it may be a good idea to choose a low
+compression level, to run @command{guix publish} behind a caching proxy, or
+to use @option{--cache}.  Using @option{--cache} has the advantage that it
+allows @command{guix publish} to add @code{Content-Length} HTTP header to
+its responses.
+
+@item --cache=@var{directory}
+@itemx -c @var{directory}
+Cache archives and meta-data (@code{.narinfo} URLs) to @var{directory} and
+only serve archives that are in cache.
+
+When this option is omitted, archives and meta-data are created on-the-fly.
+This can reduce the available bandwidth, especially when compression is
+enabled, since this may become CPU-bound.  Another drawback of the default
+mode is that the length of archives is not known in advance, so
+@command{guix publish} does not add a @code{Content-Length} HTTP header to
+its responses, which in turn prevents clients from knowing the amount of
+data being downloaded.
+
+Conversely, when @option{--cache} is used, the first request for a store
+item (@i{via} a @code{.narinfo} URL) returns 404 and triggers a background
+process to @dfn{bake} the archive---computing its @code{.narinfo} and
+compressing the archive, if needed.  Once the archive is cached in
+@var{directory}, subsequent requests succeed and are served directly from
+the cache, which guarantees that clients get the best possible bandwidth.
+
+The ``baking'' process is performed by worker threads.  By default, one
+thread per CPU core is created, but this can be customized.  See
+@option{--workers} below.
+
+When @option{--ttl} is used, cached entries are automatically deleted when
+they have expired.
+
+@item --workers=@var{N}
+When @option{--cache} is used, request the allocation of @var{N} worker
+threads to ``bake'' archives.
+
+@item --ttl=@var{ttl}
+Produce @code{Cache-Control} HTTP headers that advertise a time-to-live
+(TTL) of @var{ttl}.  @var{ttl} must denote a duration: @code{5d} means 5
+days, @code{1m} means 1 month, and so on.
+
+This allows the user's Guix to keep substitute information in cache for
+@var{ttl}.  However, note that @code{guix publish} does not itself guarantee
+that the store items it provides will indeed remain available for as long as
+@var{ttl}.
+
+Additionally, when @option{--cache} is used, cached entries that have not
+been accessed for @var{ttl} and that no longer have a corresponding item in
+the store, may be deleted.
+
+@item --nar-path=@var{path}
+Use @var{path} as the prefix for the URLs of ``nar'' files (@pxref{Aufruf von guix archive, normalized archives}).
+
+By default, nars are served at a URL such as
+@code{/nar/gzip/@dots{}-coreutils-8.25}.  This option allows you to change
+the @code{/nar} part to @var{path}.
+
+@item --public-key=@var{file}
+@itemx --private-key=@var{file}
+Use the specific @var{file}s as the public/private key pair used to sign the
+store items being published.
+
+The files must correspond to the same key pair (the private key is used for
+signing and the public key is merely advertised in the signature metadata).
+They must contain keys in the canonical s-expression format as produced by
+@command{guix archive --generate-key} (@pxref{Aufruf von guix archive}).  By
+default, @file{/etc/guix/signing-key.pub} and
+@file{/etc/guix/signing-key.sec} are used.
+
+@item --repl[=@var{port}]
+@itemx -r [@var{port}]
+Spawn a Guile REPL server (@pxref{REPL Servers,,, guile, GNU Guile Reference
+Manual}) on @var{port} (37146 by default).  This is used primarily for
+debugging a running @command{guix publish} server.
+@end table
+
+Enabling @command{guix publish} on a GuixSD system is a one-liner: just
+instantiate a @code{guix-publish-service-type} service in the
+@code{services} field of the @code{operating-system} declaration
+(@pxref{guix-publish-service-type, @code{guix-publish-service-type}}).
+
+If you are instead running Guix on a ``foreign distro'', follow these
+instructions:”
+
+@itemize
+@item
+If your host distro uses the systemd init system:
+
+@example
+# ln -s ~root/.guix-profile/lib/systemd/system/guix-publish.service \

+# systemctl start guix-publish && systemctl enable guix-publish

+@cindex verifiable builds
+@cindex @command{guix challenge}
+@cindex challenge
+Do the binaries provided by this server really correspond to the source code
+it claims to build? Is a package build process deterministic? These are the
+questions the @command{guix challenge} command attempts to answer.
+
+The former is obviously an important question: Before using a substitute
+server (@pxref{Substitute}), one had better @emph{verify} that it provides
+the right binaries, and thus @emph{challenge} it.  The latter is what
+enables the former: If package builds are deterministic, then independent
+builds of the package should yield the exact same result, bit for bit; if a
+server provides a binary different from the one obtained locally, it may be
+either corrupt or malicious.
+
+We know that the hash that shows up in @file{/gnu/store} file names is the
+hash of all the inputs of the process that built the file or
+directory---compilers, libraries, build scripts,
+etc. (@pxref{Einführung}).  Assuming deterministic build processes, one
+store file name should map to exactly one build output.  @command{guix
+challenge} checks whether there is, indeed, a single mapping by comparing
+the build outputs of several independent builds of any given store item.
+
+The command output looks like this:
+
+@smallexample

+  - 525 (8.2%) differed
+  - 1,132 (17.7%) were inconclusive
+@end smallexample
+
+@noindent
+In this example, @command{guix challenge} first scans the store to determine
+the set of locally-built derivations---as opposed to store items that were
+downloaded from a substitute server---and then queries all the substitute
+servers.  It then reports those store items for which the servers obtained a
+result different from the local build.
+
+@cindex non-determinism, in package builds
+As an example, @code{guix.example.org} always gets a different answer.
+Conversely, @code{hydra.gnu.org} agrees with local builds, except in the
+case of Git.  This might indicate that the build process of Git is
+non-deterministic, meaning that its output varies as a function of various
+things that Guix does not fully control, in spite of building packages in
+isolated environments (@pxref{Funktionalitäten}).  Most common sources of
+non-determinism include the addition of timestamps in build results, the
+inclusion of random numbers, and directory listings sorted by inode number.
+See @uref{https://reproducible-builds.org/docs/}, for more information.
+
+To find out what is wrong with this Git binary, we can do something along
+these lines (@pxref{Aufruf von guix archive}):
+
+@example
+$ wget -q -O - https://hydra.gnu.org/nar/@dots{}-git-2.5.0 \
+   | guix archive -x /tmp/git
+$ diff -ur --no-dereference /gnu/store/@dots{}-git.2.5.0 /tmp/git
+@end example
+
+This command shows the difference between the files resulting from the local
+build, and the files resulting from the build on @code{hydra.gnu.org}
+(@pxref{Overview, Comparing and Merging Files,, diffutils, Comparing and
+Merging Files}).  The @command{diff} command works great for text files.
+When binary files differ, a better option is @uref{https://diffoscope.org/,
+Diffoscope}, a tool that helps visualize differences for all kinds of files.
+
+Once you have done that work, you can tell whether the differences are due
+to a non-deterministic build process or to a malicious server.  We try hard
+to remove sources of non-determinism in packages to make it easier to verify
+substitutes, but of course, this is a process that involves not just Guix,
+but a large part of the free software community.  In the meantime,
+@command{guix challenge} is one tool to help address the problem.
+
+If you are writing packages for Guix, you are encouraged to check whether
+@code{hydra.gnu.org} and other substitute servers obtain the same build
+result as you did with:
+
+@example
+$ guix challenge @var{package}
+@end example
+
+@noindent
+where @var{package} is a package specification such as @code{guile@@2.0} or
+@code{glibc:debug}.
+
+The general syntax is:
+
+@example
+guix challenge @var{options} [@var{packages}@dots{}]
+@end example
+
+When a difference is found between the hash of a locally-built item and that
+of a server-provided substitute, or among substitutes provided by different
+servers, the command displays it as in the example above and its exit code
+is 2 (other non-zero exit codes denote other kinds of errors.)
+
+The one option that matters is:
+
+@table @code
+
+@item --substitute-urls=@var{URLs}
+Consider @var{urls} the whitespace-separated list of substitute source URLs
+to compare to.
+
+@item --verbose
+@itemx -v
+Show details about matches (identical contents) in addition to information
+about mismatches.

+@cindex sharing store items across machines
+@cindex transferring store items across machines
+The @command{guix copy} command copies items from the store of one machine
+to that of another machine over a secure shell (SSH)
+connection@footnote{This command is available only when Guile-SSH was
+found.  @xref{Voraussetzungen}, for details.}.  For example, the following
+command copies the @code{coreutils} package, the user's profile, and all
+their dependencies over to @var{host}, logged in as @var{user}:
+
+@example
+guix copy --to=@var{user}@@@var{host} \
+          coreutils `readlink -f ~/.guix-profile`
+@end example
+
+If some of the items to be copied are already present on @var{host}, they
+are not actually sent.
+
+The command below retrieves @code{libreoffice} and @code{gimp} from
+@var{host}, assuming they are available there:
+
+@example
+guix copy --from=@var{host} libreoffice gimp
+@end example
+
+The SSH connection is established using the Guile-SSH client, which is
+compatible with OpenSSH: it honors @file{~/.ssh/known_hosts} and
+@file{~/.ssh/config}, and uses the SSH agent for authentication.
+
+The key used to sign items that are sent must be accepted by the remote
+machine.  Likewise, the key used by the remote machine to sign items you are
+retrieving must be in @file{/etc/guix/acl} so it is accepted by your own
+daemon.  @xref{Aufruf von guix archive}, for more information about store item
+authentication.
+
+The general syntax is:
+
+@example
+guix copy [--to=@var{spec}|--from=@var{spec}] @var{items}@dots{}
+@end example
+
+You must always specify one of the following options:
+
+@table @code
+@item --to=@var{spec}
+@itemx --from=@var{spec}
+Specify the host to send to or receive from.  @var{spec} must be an SSH spec
+such as @code{example.org}, @code{charlie@@example.org}, or
+@code{charlie@@example.org:2222}.

+
+The @var{items} can be either package names, such as @code{gimp}, or store
+items, such as @file{/gnu/store/@dots{}-idutils-4.6}.

+provided by the server, the size the corresponding store items occupy in the

+The second part gives continuous integration (CI) statistics, if the server
+supports it.
+
+To achieve that, @command{guix weather} queries over HTTP(S) meta-data
+(@dfn{narinfos}) for all the relevant store items.  Like @command{guix

+@item --system=@var{System}
+@itemx -s @var{system}
+Query substitutes for @var{system}---e.g., @code{aarch64-linux}.  This
+option can be repeated, in which case @command{guix weather} will query
+substitutes for several system types.
+
+@item --manifest=@var{Datei}
+Instead of querying substitutes for all the packages, only ask for those

+continuous integration tool; their process identifier (PID) is given by the
+@code{ClientPID} field.  The @code{SessionPID} field gives the PID of the
+@command{guix-daemon} sub-process of this particular session.
+
+The @code{LockHeld} fields show which store items are currently locked by
+this session, which corresponds to store items being built or substituted
+(the @code{LockHeld} field is not displayed when @command{guix processes} is
+not running as root.)  Last, by looking at the @code{ChildProcess} field, we
+understand that these three builds are being offloaded (@pxref{Auslagern des Daemons einrichten}).
+
+The output is in Recutils format so we can use the handy @command{recsel}
+command to select sessions of interest (@pxref{Selection Expressions,,,
+recutils, GNU recutils manual}).  As an example, the command shows the
+command line and PID of the client that triggered the build of a Perl
+package:
+
+@example
+$ sudo guix processes | \
+    recsel -p ClientPID,ClientCommand -e 'LockHeld ~ "perl"'
+ClientPID: 19419
+ClientCommand: cuirass --cache-directory /var/cache/cuirass @dots{}

+@cindex Guix System Distribution
+@cindex GuixSD
+Guix comes with a distribution of the GNU system consisting entirely of free
+software@footnote{The term ``free'' here refers to the
+@url{http://www.gnu.org/philosophy/free-sw.html,freedom provided to users of
+that software}.}.  The distribution can be installed on its own
+(@pxref{Systeminstallation}), but it is also possible to install Guix as a
+package manager on top of an installed GNU/Linux system
+(@pxref{Installation}).  To distinguish between the two, we refer to the
+standalone distribution as the Guix System Distribution, or GuixSD.
+
+The distribution provides core GNU packages such as GNU libc, GCC, and
+Binutils, as well as many GNU and non-GNU applications.  The complete list
+of available packages can be browsed
+@url{http://www.gnu.org/software/guix/packages,on-line} or by running
+@command{guix package} (@pxref{Aufruf von guix package}):
+
+@example
+guix package --list-available
+@end example
+
+Our goal is to provide a practical 100% free software distribution of
+Linux-based and other variants of GNU, with a focus on the promotion and
+tight integration of GNU components, and an emphasis on programs and tools
+that help users exert that freedom.
+
+Packages are currently available on the following platforms:
+
+@table @code
+
+@item x86_64-linux
+Intel/AMD @code{x86_64} architecture, Linux-Libre kernel;
+

+
+@item armhf-linux
+ARMv7-A architecture with hard float, Thumb-2 and NEON, using the EABI
+hard-float application binary interface (ABI), and Linux-Libre kernel.

+@subsection Einschränkungen
+
+As of version @value{VERSION}, the Guix System Distribution (GuixSD) is not
+production-ready.  It may contain bugs and lack important features.  Thus,
+if you are looking for a stable production system that respects your freedom
+as a computer user, a good solution at this point is to consider
+@url{http://www.gnu.org/distros/free-distros.html, one of the more
+established GNU/Linux distributions}.  We hope you can soon switch to the
+GuixSD without fear, of course.  In the meantime, you can also keep using
+your distribution and try out the package manager on top of it
+(@pxref{Installation}).
+
+Before you proceed with the installation, be aware of the following
+noteworthy limitations applicable to version @value{VERSION}:
+
+@itemize
+@item
+The installation process does not include a graphical user interface and
+requires familiarity with GNU/Linux (see the following subsections to get a
+feel of what that means.)
+
+@item
+Support for the Logical Volume Manager (LVM) is missing.
+
+@item
+More and more system services are provided (@pxref{Dienste}), but some may
+be missing.
+
+@item
+More than 7,500 packages are available, but you might occasionally find that
+a useful package is missing.
+
+@item
+GNOME, Xfce, LXDE, and Enlightenment are available (@pxref{Desktop-Dienste}), as well as a number of X11 window managers.  However, some
+graphical applications may be missing, as well as KDE.

+@node Hardware-Überlegungen
+@subsection Hardware-Überlegungen
+
+@cindex hardware support on GuixSD
+GNU@tie{}GuixSD focuses on respecting the user's computing freedom.  It
+builds around the kernel Linux-libre, which means that only hardware for
+which free software drivers and firmware exist is supported.  Nowadays, a
+wide range of off-the-shelf hardware is supported on GNU/Linux-libre---from
+keyboards to graphics cards to scanners and Ethernet controllers.
+Unfortunately, there are still areas where hardware vendors deny users
+control over their own computing, and such hardware is not supported on
+GuixSD.
+
+@cindex WiFi, hardware support
+One of the main areas where free drivers or firmware are lacking is WiFi
+devices.  WiFi devices known to work include those using Atheros chips
+(AR9271 and AR7010), which corresponds to the @code{ath9k} Linux-libre
+driver, and those using Broadcom/AirForce chips (BCM43xx with Wireless-Core
+Revision 5), which corresponds to the @code{b43-open} Linux-libre driver.
+Free firmware exists for both and is available out-of-the-box on GuixSD, as
+part of @var{%base-firmware} (@pxref{„operating-system“-Referenz,
+@code{firmware}}).
+
+@cindex RYF, Respects Your Freedom
+The @uref{https://www.fsf.org/, Free Software Foundation} runs
+@uref{https://www.fsf.org/ryf, @dfn{Respects Your Freedom}} (RYF), a
+certification program for hardware products that respect your freedom and
+your privacy and ensure that you have control over your device.  We
+encourage you to check the list of RYF-certified devices.
+
+Another useful resource is the @uref{https://www.h-node.org/, H-Node} web
+site.  It contains a catalog of hardware devices with information about
+their support in GNU/Linux.

+
+@node Installation von USB-Stick oder DVD
+@subsection Installation von USB-Stick oder DVD
+
+An ISO-9660 installation image that can be written to a USB stick or burnt
+to a DVD can be downloaded from
+@indicateurl{https://alpha.gnu.org/gnu/guix/guixsd-install-@value{VERSION}.@var{system}.iso.xz},
+where @var{system} is one of:
+
+@table @code

+und den Befehl @code{gpg --verify} erneut ausführen.
+
+This image contains the tools necessary for an installation.  It is meant to
+be copied @emph{as is} to a large-enough USB stick or DVD.
+
+@unnumberedsubsubsec Copying to a USB Stick
+
+To copy the image to a USB stick, follow these steps:
+
+@enumerate
+@item
+Decompress the image using the @command{xz} command:
+
+@example
+xz -d guixsd-install-@value{VERSION}.@var{system}.iso.xz
+@end example
+
+@item
+Insert a USB stick of 1@tie{}GiB or more into your machine, and determine
+its device name.  Assuming that the USB stick is known as @file{/dev/sdX},
+copy the image with:
+
+@example
+dd if=guixsd-install-@value{VERSION}.x86_64-linux.iso of=/dev/sdX
+sync
+@end example
+
+Access to @file{/dev/sdX} usually requires root privileges.
+@end enumerate
+
+@unnumberedsubsubsec Burning on a DVD
+
+To copy the image to a DVD, follow these steps:
+
+@enumerate
+@item
+Decompress the image using the @command{xz} command:
+
+@example
+xz -d guixsd-install-@value{VERSION}.@var{system}.iso.xz
+@end example
+
+@item
+Insert a blank DVD into your machine, and determine its device name.
+Assuming that the DVD drive is known as @file{/dev/srX}, copy the image
+with:
+
+@example
+growisofs -dvd-compat -Z /dev/srX=guixsd-install-@value{VERSION}.x86_64.iso
+@end example
+
+Access to @file{/dev/srX} usually requires root privileges.
+@end enumerate
+
+@unnumberedsubsubsec Booting
+
+Once this is done, you should be able to reboot the system and boot from the
+USB stick or DVD.  The latter usually requires you to get in the BIOS or
+UEFI boot menu, where you can choose to boot from the USB stick.
+
+@xref{GuixSD in einer VM installieren}, if, instead, you would like to install
+GuixSD in a virtual machine (VM).
+
+
+@node Vor der Installation
+@subsection Vor der Installation
+
+Once you have successfully booted your computer using the installation
+medium, you should end up with a root prompt.  Several console TTYs are
+configured and can be used to run commands as root.  TTY2 shows this
+documentation, browsable using the Info reader commands (@pxref{Top,,,
+info-stnd, Stand-alone GNU Info}).  The installation system runs the GPM
+mouse daemon, which allows you to select text with the left mouse button and
+to paste it with the middle button.
+
+@quotation Anmerkung
+Installation requires access to the Internet so that any missing
+dependencies of your system configuration can be downloaded.  See the
+``Networking'' section below.
+@end quotation
+
+The installation system includes many common tools needed for this task.
+But it is also a full-blown GuixSD system, which means that you can install
+additional packages, should you need it, using @command{guix package}
+(@pxref{Aufruf von guix package}).
+
+@subsubsection Keyboard Layout
+
+@cindex keyboard layout
+The installation image uses the US qwerty keyboard layout.  If you want to
+change it, you can use the @command{loadkeys} command.  For example, the
+following command selects the Dvorak keyboard layout:
+
+@example
+loadkeys dvorak
+@end example
+
+See the files under @file{/run/current-system/profile/share/keymaps} for a
+list of available keyboard layouts.  Run @command{man loadkeys} for more
+information.
+
+@subsubsection Networking
+
+Run the following command to see what your network interfaces are called:
+
+@example
+ifconfig -a
+@end example
+
+@noindent
+@dots{} or, using the GNU/Linux-specific @command{ip} command:
+
+@example
+ip a
+@end example
+
+@c http://cgit.freedesktop.org/systemd/systemd/tree/src/udev/udev-builtin-net_id.c#n20
+Wired interfaces have a name starting with @samp{e}; for example, the
+interface corresponding to the first on-board Ethernet controller is called
+@samp{eno1}.  Wireless interfaces have a name starting with @samp{w}, like
+@samp{w1p2s0}.
+
+@table @asis
+@item Wired connection
+To configure a wired network run the following command, substituting
+@var{interface} with the name of the wired interface you want to use.
+
+@example
+ifconfig @var{interface} up
+@end example
+
+@item Wireless connection
+@cindex wireless
+@cindex WiFi
+To configure wireless networking, you can create a configuration file for
+the @command{wpa_supplicant} configuration tool (its location is not
+important) using one of the available text editors such as @command{nano}:
+
+@example
+nano wpa_supplicant.conf
+@end example
+
+As an example, the following stanza can go to this file and will work for
+many wireless networks, provided you give the actual SSID and passphrase for
+the network you are connecting to:
+
+@example
+network=@{
+  ssid="@var{my-ssid}"
+  key_mgmt=WPA-PSK
+  psk="the network's secret passphrase"
+@}
+@end example
+
+Start the wireless service and run it in the background with the following
+command (substitute @var{interface} with the name of the network interface
+you want to use):
+
+@example
+wpa_supplicant -c wpa_supplicant.conf -i @var{interface} -B
+@end example
+
+Run @command{man wpa_supplicant} for more information.
+@end table
+
+@cindex DHCP
+At this point, you need to acquire an IP address.  On a network where IP
+addresses are automatically assigned @i{via} DHCP, you can run:
+
+@example
+dhclient -v @var{interface}
+@end example
+
+Try to ping a server to see if networking is up and running:
+
+@example
+ping -c 3 gnu.org
+@end example
+
+Setting up network access is almost always a requirement because the image
+does not contain all the software and tools that may be needed.
+
+@cindex installing over SSH
+If you want to, you can continue the installation remotely by starting an
+SSH server:
+
+@example
+herd start ssh-daemon
+@end example
+
+Make sure to either set a password with @command{passwd}, or configure
+OpenSSH public key authentication before logging in.
+
+@subsubsection Disk Partitioning
+
+Unless this has already been done, the next step is to partition, and then
+format the target partition(s).
+
+The installation image includes several partitioning tools, including Parted
+(@pxref{Overview,,, parted, GNU Parted User Manual}), @command{fdisk}, and
+@command{cfdisk}.  Run it and set up your disk with the partition layout you
+want:
+
+@example
+cfdisk
+@end example
+
+If your disk uses the GUID Partition Table (GPT) format and you plan to
+install BIOS-based GRUB (which is the default), make sure a BIOS Boot
+Partition is available (@pxref{BIOS installation,,, grub, GNU GRUB manual}).
+
+@cindex EFI, installation
+@cindex UEFI, installation
+@cindex ESP, EFI system partition
+If you instead wish to use EFI-based GRUB, a FAT32 @dfn{EFI System
+Partition} (ESP) is required.  This partition should be mounted at
+@file{/boot/efi} and must have the @code{esp} flag set.  E.g., for
+@command{parted}:
+
+@example
+parted /dev/sda set 1 esp on
+@end example
+
+@quotation Anmerkung
+@vindex grub-bootloader
+@vindex grub-efi-bootloader
+Unsure whether to use EFI- or BIOS-based GRUB? If the directory
+@file{/sys/firmware/efi} exists in the installation image, then you should
+probably perform an EFI installation, using @code{grub-efi-bootloader}.
+Otherwise you should use the BIOS-based GRUB, known as
+@code{grub-bootloader}.  @xref{Bootloader-Konfiguration}, for more info on
+bootloaders.
+@end quotation
+
+Once you are done partitioning the target hard disk drive, you have to
+create a file system on the relevant partition(s)@footnote{Currently GuixSD
+only supports ext4 and btrfs file systems.  In particular, code that reads
+file system UUIDs and labels only works for these file system types.}.  For
+the ESP, if you have one and assuming it is @file{/dev/sda1}, run:
+
+@example
+mkfs.fat -F32 /dev/sda1
+@end example
+
+Preferably, assign file systems a label so that you can easily and reliably
+refer to them in @code{file-system} declarations (@pxref{Dateisysteme}).
+This is typically done using the @code{-L} option of @command{mkfs.ext4} and
+related commands.  So, assuming the target root partition lives at
+@file{/dev/sda2}, a file system with the label @code{my-root} can be created
+with:
+
+@example
+mkfs.ext4 -L my-root /dev/sda2
+@end example
+
+@cindex encrypted disk
+If you are instead planning to encrypt the root partition, you can use the
+Cryptsetup/LUKS utilities to do that (see @inlinefmtifelse{html,
+@uref{https://linux.die.net/man/8/cryptsetup, @code{man cryptsetup}},
+@code{man cryptsetup}} for more information.)  Assuming you want to store
+the root partition on @file{/dev/sda2}, the command sequence would be along
+these lines:
+
+@example
+cryptsetup luksFormat /dev/sda2
+cryptsetup open --type luks /dev/sda2 my-partition
+mkfs.ext4 -L my-root /dev/mapper/my-partition
+@end example
+
+Once that is done, mount the target file system under @file{/mnt} with a
+command like (again, assuming @code{my-root} is the label of the root file
+system):
+
+@example
+mount LABEL=my-root /mnt
+@end example
+
+Also mount any other file systems you would like to use on the target system
+relative to this path.  If you have @file{/boot} on a separate partition for
+example, mount it at @file{/mnt/boot} now so it is found by @code{guix
+system init} afterwards.
+
+Finally, if you plan to use one or more swap partitions (@pxref{Memory
+Concepts, swap space,, libc, The GNU C Library Reference Manual}), make sure
+to initialize them with @command{mkswap}.  Assuming you have one swap
+partition on @file{/dev/sda3}, you would run:
+
+@example
+mkswap /dev/sda3
+swapon /dev/sda3
+@end example
+
+Alternatively, you may use a swap file.  For example, assuming that in the
+new system you want to use the file @file{/swapfile} as a swap file, you
+would run@footnote{This example will work for many types of file systems
+(e.g., ext4).  However, for copy-on-write file systems (e.g., btrfs), the
+required steps may be different.  For details, see the manual pages for
+@command{mkswap} and @command{swapon}.}:
+
+@example
+# This is 10 GiB of swap space.  Adjust "count" to change the size.
+dd if=/dev/zero of=/mnt/swapfile bs=1MiB count=10240
+# For security, make the file readable and writable only by root.
+chmod 600 /mnt/swapfile
+mkswap /mnt/swapfile
+swapon /mnt/swapfile
+@end example
+
+Note that if you have encrypted the root partition and created a swap file
+in its file system as described above, then the encryption also protects the
+swap file, just like any other file in that file system.
+
+@node Fortfahren mit der Installation
+@subsection Fortfahren mit der Installation
+
+With the target partitions ready and the target root mounted on @file{/mnt},
+we're ready to go.  First, run:
+
+@example
+herd start cow-store /mnt
+@end example
+
+This makes @file{/gnu/store} copy-on-write, such that packages added to it
+during the installation phase are written to the target disk on @file{/mnt}
+rather than kept in memory.  This is necessary because the first phase of
+the @command{guix system init} command (see below) entails downloads or
+builds to @file{/gnu/store} which, initially, is an in-memory file system.
+
+Next, you have to edit a file and provide the declaration of the operating
+system to be installed.  To that end, the installation system comes with
+three text editors.  We recommend GNU nano (@pxref{Top,,, nano, GNU nano
+Manual}), which supports syntax highlighting and parentheses matching; other
+editors include GNU Zile (an Emacs clone), and nvi (a clone of the original
+BSD @command{vi} editor).  We strongly recommend storing that file on the
+target root file system, say, as @file{/mnt/etc/config.scm}.  Failing to do
+that, you will have lost your configuration file once you have rebooted into
+the newly-installed system.
+
+@xref{Das Konfigurationssystem nutzen}, for an overview of the configuration
+file.  The example configurations discussed in that section are available
+under @file{/etc/configuration} in the installation image.  Thus, to get
+started with a system configuration providing a graphical display server (a
+``desktop'' system), you can run something along these lines:
+
+@example
+# mkdir /mnt/etc
+# cp /etc/configuration/desktop.scm /mnt/etc/config.scm
+# nano /mnt/etc/config.scm
+@end example
+
+You should pay attention to what your configuration file contains, and in
+particular:
+
+@itemize
+@item
+Make sure the @code{bootloader-configuration} form refers to the target you
+want to install GRUB on.  It should mention @code{grub-bootloader} if you
+are installing GRUB in the legacy way, or @code{grub-efi-bootloader} for
+newer UEFI systems.  For legacy systems, the @code{target} field names a
+device, like @code{/dev/sda}; for UEFI systems it names a path to a mounted
+EFI partition, like @code{/boot/efi}, and do make sure the path is actually
+mounted.
+
+@item
+Be sure that your file system labels match the value of their respective
+@code{device} fields in your @code{file-system} configuration, assuming your
+@code{file-system} configuration uses the @code{file-system-label} procedure
+in its @code{device} field.
+
+@item
+If there are encrypted or RAID partitions, make sure to add a
+@code{mapped-devices} field to describe them (@pxref{Abgebildete Geräte}).
+@end itemize
+
+Once you are done preparing the configuration file, the new system must be
+initialized (remember that the target root file system is mounted under
+@file{/mnt}):
+
+@example
+guix system init /mnt/etc/config.scm /mnt
+@end example
+
+@noindent
+This copies all the necessary files and installs GRUB on @file{/dev/sdX},
+unless you pass the @option{--no-bootloader} option.  For more information,
+@pxref{Aufruf von guix system}.  This command may trigger downloads or builds
+of missing packages, which can take some time.
+
+Once that command has completed---and hopefully succeeded!---you can run
+@command{reboot} and boot into the new system.  The @code{root} password in
+the new system is initially empty; other users' passwords need to be
+initialized by running the @command{passwd} command as @code{root}, unless
+your configuration specifies otherwise (@pxref{user-account-password, user
+account passwords}).
+
+@cindex upgrading GuixSD
+From then on, you can update GuixSD whenever you want by running
+@command{guix pull} as @code{root} (@pxref{Aufruf von guix pull}), and then
+running @command{guix system reconfigure} to build a new system generation
+with the latest packages and services (@pxref{Aufruf von guix system}).  We
+recommend doing that regularly so that your system includes the latest
+security updates (@pxref{Sicherheitsaktualisierungen}).

+private server (VPS) rather than on your beloved machine, this section is
+for you.
+
+To boot a @uref{http://qemu.org/,QEMU} VM for installing GuixSD in a disk
+image, follow these steps:
+
+@enumerate
+@item
+First, retrieve and decompress the GuixSD installation image as described
+previously (@pxref{Installation von USB-Stick oder DVD}).
+
+@item
+Create a disk image that will hold the installed system.  To make a
+qcow2-formatted disk image, use the @command{qemu-img} command:
+
+@example
+qemu-img create -f qcow2 guixsd.img 50G
+@end example
+
+The resulting file will be much smaller than 50 GB (typically less than 1
+MB), but it will grow as the virtualized storage device is filled up.
+
+@item
+Boot the USB installation image in an VM:
+
+@example
+qemu-system-x86_64 -m 1024 -smp 1 \
+  -net user -net nic,model=virtio -boot menu=on \
+  -drive file=guixsd-install-@value{VERSION}.@var{system}.iso \
+  -drive file=guixsd.img
+@end example
+
+The ordering of the drives matters.
+
+In the VM console, quickly press the @kbd{F12} key to enter the boot menu.
+Then press the @kbd{2} key and the @kbd{RET} key to validate your selection.
+
+@item
+You're now root in the VM, proceed with the installation process.
+@xref{Vor der Installation}, and follow the instructions.
+@end enumerate
+
+Once installation is complete, you can boot the system that's on your
+@file{guixsd.img} image.  @xref{GuixSD in einer VM starten}, for how to do that.
+
+@node Ein Abbild zur Installation erstellen
+@subsection Ein Abbild zur Installation erstellen
+
+@cindex installation image
+The installation image described above was built using the @command{guix
+system} command, specifically:
+
+@example
+guix system disk-image gnu/system/install.scm
+@end example
+
+Have a look at @file{gnu/system/install.scm} in the source tree, and see
+also @ref{Aufruf von guix system} for more information about the installation
+image.
+
+@subsection Building the Installation Image for ARM Boards
+
+Many ARM boards require a specific variant of the
+@uref{http://www.denx.de/wiki/U-Boot/, U-Boot} bootloader.
+
+If you build a disk image and the bootloader is not available otherwise (on
+another boot drive etc), it's advisable to build an image that includes the
+bootloader, specifically:
+
+@example
+guix system disk-image --system=armhf-linux -e '((@@ (gnu system install) os-with-u-boot) (@@ (gnu system install) installation-os) "A20-OLinuXino-Lime2")'
+@end example
+
+@code{A20-OLinuXino-Lime2} is the name of the board.  If you specify an
+invalid board, a list of possible boards will be printed.
+
+@node Systemkonfiguration
+@section Systemkonfiguration
+
+@cindex system configuration
+The Guix System Distribution supports a consistent whole-system
+configuration mechanism.  By that we mean that all aspects of the global
+system configuration---such as the available system services, timezone and
+locale settings, user accounts---are declared in a single place.  Such a
+@dfn{system configuration} can be @dfn{instantiated}---i.e., effected.
+
+@c Yes, we're talking of Puppet, Chef, & co. here.  ↑
+One of the advantages of putting all the system configuration under the
+control of Guix is that it supports transactional system upgrades, and makes
+it possible to roll back to a previous system instantiation, should
+something go wrong with the new one (@pxref{Funktionalitäten}).  Another advantage
+is that it makes it easy to replicate the exact same configuration across
+different machines, or at different points in time, without having to resort
+to additional administration tools layered on top of the own tools of the
+system.
+
+This section describes this mechanism.  First we focus on the system
+administrator's viewpoint---explaining how the system is configured and
+instantiated.  Then we show how this mechanism can be extended, for instance
+to support new system services.

+@subsection Das Konfigurationssystem nutzen
+
+The operating system is configured by providing an @code{operating-system}
+declaration in a file that can then be passed to the @command{guix system}
+command (@pxref{Aufruf von guix system}).  A simple setup, with the default
+system services, the default Linux-Libre kernel, initial RAM disk, and boot
+loader looks like this:
+
+@findex operating-system
+@lisp
+@include os-config-bare-bones.texi
+@end lisp
+
+This example should be self-describing.  Some of the fields defined above,
+such as @code{host-name} and @code{bootloader}, are mandatory.  Others, such
+as @code{packages} and @code{services}, can be omitted, in which case they
+get a default value.
+
+Below we discuss the effect of some of the most important fields
+(@pxref{„operating-system“-Referenz}, for details about all the available
+fields), and how to @dfn{instantiate} the operating system using
+@command{guix system}.
+
+@unnumberedsubsubsec Bootloader
+
+@cindex legacy boot, on Intel machines
+@cindex BIOS boot, on Intel machines
+@cindex UEFI boot
+@cindex EFI boot
+The @code{bootloader} field describes the method that will be used to boot
+your system.  Machines based on Intel processors can boot in ``legacy'' BIOS
+mode, as in the example above.  However, more recent machines rely instead
+on the @dfn{Unified Extensible Firmware Interface} (UEFI) to boot.  In that
+case, the @code{bootloader} field should contain something along these
+lines:
+
+@example
+(bootloader-configuration
+  (bootloader grub-efi-bootloader)
+  (target "/boot/efi"))
+@end example
+
+@xref{Bootloader-Konfiguration}, for more information on the available
+configuration options.
+
+@unnumberedsubsubsec Globally-Visible Packages
+
+@vindex %base-packages
+The @code{packages} field lists packages that will be globally visible on
+the system, for all user accounts---i.e., in every user's @code{PATH}
+environment variable---in addition to the per-user profiles (@pxref{Aufruf von guix package}).  The @var{%base-packages} variable provides all the tools
+one would expect for basic user and administrator tasks---including the GNU
+Core Utilities, the GNU Networking Utilities, the GNU Zile lightweight text
+editor, @command{find}, @command{grep}, etc.  The example above adds
+GNU@tie{}Screen to those, taken from the @code{(gnu packages screen)} module
+(@pxref{Paketmodule}).  The @code{(list package output)} syntax can be
+used to add a specific output of a package:
+
+@lisp
+(use-modules (gnu packages))
+(use-modules (gnu packages dns))
+
+(operating-system
+  ;; ...
+  (packages (cons (list bind "utils")
+                  %base-packages)))
+@end lisp
+
+@findex specification->package
+Referring to packages by variable name, like @code{bind} above, has the
+advantage of being unambiguous; it also allows typos and such to be
+diagnosed right away as ``unbound variables''.  The downside is that one
+needs to know which module defines which package, and to augment the
+@code{use-package-modules} line accordingly.  To avoid that, one can use the
+@code{specification->package} procedure of the @code{(gnu packages)} module,
+which returns the best package for a given name or name and version:
+
+@lisp
+(use-modules (gnu packages))
+
+(operating-system
+  ;; ...
+  (packages (append (map specification->package
+                         '("tcpdump" "htop" "gnupg@@2.0"))
+                    %base-packages)))
+@end lisp
+
+@unnumberedsubsubsec System Services
+
+@cindex services
+@vindex %base-services
+The @code{services} field lists @dfn{system services} to be made available
+when the system starts (@pxref{Dienste}).  The @code{operating-system}
+declaration above specifies that, in addition to the basic services, we want
+the @command{lshd} secure shell daemon listening on port 2222
+(@pxref{Netzwerkdienste, @code{lsh-service}}).  Under the hood,
+@code{lsh-service} arranges so that @code{lshd} is started with the right
+command-line options, possibly with supporting configuration files generated
+as needed (@pxref{Dienste definieren}).
+
+@cindex customization, of services
+@findex modify-services
+Occasionally, instead of using the base services as is, you will want to
+customize them.  To do this, use @code{modify-services} (@pxref{Service-Referenz, @code{modify-services}}) to modify the list.
+
+For example, suppose you want to modify @code{guix-daemon} and Mingetty (the
+console log-in) in the @var{%base-services} list (@pxref{Basisdienste,
+@code{%base-services}}).  To do that, you can write the following in your
+operating system declaration:
+
+@lisp
+(define %my-services
+  ;; My very own list of services.
+  (modify-services %base-services
+    (guix-service-type config =>
+                       (guix-configuration
+                        (inherit config)
+                        (use-substitutes? #f)
+                        (extra-options '("--gc-keep-derivations"))))
+    (mingetty-service-type config =>
+                           (mingetty-configuration
+                            (inherit config)))))
+
+(operating-system
+  ;; @dots{}
+  (services %my-services))
+@end lisp
+
+This changes the configuration---i.e., the service parameters---of the
+@code{guix-service-type} instance, and that of all the
+@code{mingetty-service-type} instances in the @var{%base-services} list.
+Observe how this is accomplished: first, we arrange for the original
+configuration to be bound to the identifier @code{config} in the @var{body},
+and then we write the @var{body} so that it evaluates to the desired
+configuration.  In particular, notice how we use @code{inherit} to create a
+new configuration which has the same values as the old configuration, but
+with a few modifications.
+
+@cindex encrypted disk
+The configuration for a typical ``desktop'' usage, with an encrypted root
+partition, the X11 display server, GNOME and Xfce (users can choose which of
+these desktop environments to use at the log-in screen by pressing
+@kbd{F1}), network management, power management, and more, would look like
+this:
+
+@lisp
+@include os-config-desktop.texi
+@end lisp
+
+A graphical system with a choice of lightweight window managers instead of
+full-blown desktop environments would look like this:
+
+@lisp
+@include os-config-lightweight-desktop.texi
+@end lisp
+
+This example refers to the @file{/boot/efi} file system by its UUID,
+@code{1234-ABCD}.  Replace this UUID with the right UUID on your system, as
+returned by the @command{blkid} command.
+
+@xref{Desktop-Dienste}, for the exact list of services provided by
+@var{%desktop-services}.  @xref{X.509-Zertifikate}, for background
+information about the @code{nss-certs} package that is used here.
+
+Again, @var{%desktop-services} is just a list of service objects.  If you
+want to remove services from there, you can do so using the procedures for
+list filtering (@pxref{SRFI-1 Filtering and Partitioning,,, guile, GNU Guile
+Reference Manual}).  For instance, the following expression returns a list
+that contains all the services in @var{%desktop-services} minus the Avahi
+service:
+
+@example
+(remove (lambda (service)
+          (eq? (service-kind service) avahi-service-type))
+        %desktop-services)
+@end example
+
+@unnumberedsubsubsec Instantiating the System
+
+Assuming the @code{operating-system} declaration is stored in the
+@file{my-system-config.scm} file, the @command{guix system reconfigure
+my-system-config.scm} command instantiates that configuration, and makes it
+the default GRUB boot entry (@pxref{Aufruf von guix system}).
+
+The normal way to change the system configuration is by updating this file
+and re-running @command{guix system reconfigure}.  One should never have to
+touch files in @file{/etc} or to run commands that modify the system state
+such as @command{useradd} or @command{grub-install}.  In fact, you must
+avoid that since that would not only void your warranty but also prevent you
+from rolling back to previous versions of your system, should you ever need
+to.
+
+@cindex roll-back, of the operating system
+Speaking of roll-back, each time you run @command{guix system reconfigure},
+a new @dfn{generation} of the system is created---without modifying or
+deleting previous generations.  Old system generations get an entry in the
+bootloader boot menu, allowing you to boot them in case something went wrong
+with the latest generation.  Reassuring, no? The @command{guix system
+list-generations} command lists the system generations available on disk.
+It is also possible to roll back the system via the commands @command{guix
+system roll-back} and @command{guix system switch-generation}.
+
+Although the @command{guix system reconfigure} command will not modify
+previous generations, you must take care when the current generation is not
+the latest (e.g., after invoking @command{guix system roll-back}), since the
+operation might overwrite a later generation (@pxref{Aufruf von guix system}).
+
+@unnumberedsubsubsec The Programming Interface
+
+At the Scheme level, the bulk of an @code{operating-system} declaration is
+instantiated with the following monadic procedure (@pxref{Die Store-Monade}):
+
+@deffn {Monadic Procedure} operating-system-derivation os
+Return a derivation that builds @var{os}, an @code{operating-system} object
+(@pxref{Ableitungen}).
+
+The output of the derivation is a single directory that refers to all the
+packages, configuration files, and other supporting files needed to
+instantiate @var{os}.
+@end deffn
+
+This procedure is provided by the @code{(gnu system)} module.  Along with
+@code{(gnu services)} (@pxref{Dienste}), this module contains the guts of
+GuixSD.  Make sure to visit it!
+

+
+@end table
+@end deftp
+
+@node Dateisysteme
+@subsection Dateisysteme
+
+The list of file systems to be mounted is specified in the
+@code{file-systems} field of the operating system declaration (@pxref{Das Konfigurationssystem nutzen}).  Each file system is declared using the
+@code{file-system} form, like this:
+
+@example
+(file-system
+  (mount-point "/home")
+  (device "/dev/sda3")
+  (type "ext4"))
+@end example
+
+As usual, some of the fields are mandatory---those shown in the example
+above---while others can be omitted.  These are described below.
+
+@deftp {Data Type} file-system
+Objects of this type represent file systems to be mounted.  They contain the
+following members:
+
+@table @asis
+@item @code{type}
+This is a string specifying the type of the file system---e.g.,
+@code{"ext4"}.
+
+@item @code{mount-point}
+This designates the place where the file system is to be mounted.
+
+@item @code{device}
+This names the ``source'' of the file system.  It can be one of three
+things: a file system label, a file system UUID, or the name of a
+@file{/dev} node.  Labels and UUIDs offer a way to refer to file systems
+without having to hard-code their actual device name@footnote{Note that,
+while it is tempting to use @file{/dev/disk/by-uuid} and similar device
+names to achieve the same result, this is not recommended: These special
+device nodes are created by the udev daemon and may be unavailable at the
+time the device is mounted.}.
+
+@findex file-system-label
+File system labels are created using the @code{file-system-label} procedure,
+UUIDs are created using @code{uuid}, and @file{/dev} node are plain
+strings.  Here's an example of a file system referred to by its label, as
+shown by the @command{e2label} command:
+
+@example
+(file-system
+  (mount-point "/home")
+  (type "ext4")
+  (device (file-system-label "my-home")))
+@end example
+
+@findex uuid
+UUIDs are converted from their string representation (as shown by the
+@command{tune2fs -l} command) using the @code{uuid} form@footnote{The
+@code{uuid} form expects 16-byte UUIDs as defined in
+@uref{https://tools.ietf.org/html/rfc4122, RFC@tie{}4122}.  This is the form
+of UUID used by the ext2 family of file systems and others, but it is
+different from ``UUIDs'' found in FAT file systems, for instance.}, like
+this:
+
+@example
+(file-system
+  (mount-point "/home")
+  (type "ext4")
+  (device (uuid "4dab5feb-d176-45de-b287-9b0a6e4c01cb")))
+@end example
+
+When the source of a file system is a mapped device (@pxref{Abgebildete Geräte}), its @code{device} field @emph{must} refer to the mapped device
+name---e.g., @file{"/dev/mapper/root-partition"}.  This is required so that
+the system knows that mounting the file system depends on having the
+corresponding device mapping established.
+
+@item @code{flags} (default: @code{'()})
+This is a list of symbols denoting mount flags.  Recognized flags include
+@code{read-only}, @code{bind-mount}, @code{no-dev} (disallow access to
+special files), @code{no-suid} (ignore setuid and setgid bits), and
+@code{no-exec} (disallow program execution.)
+
+@item @code{options} (default: @code{#f})
+This is either @code{#f}, or a string denoting mount options.
+
+@item @code{mount?} (default: @code{#t})
+This value indicates whether to automatically mount the file system when the
+system is brought up.  When set to @code{#f}, the file system gets an entry
+in @file{/etc/fstab} (read by the @command{mount} command) but is not
+automatically mounted.
+
+@item @code{needed-for-boot?} (default: @code{#f})
+This Boolean value indicates whether the file system is needed when
+booting.  If that is true, then the file system is mounted when the initial
+RAM disk (initrd) is loaded.  This is always the case, for instance, for the
+root file system.
+
+@item @code{check?} (default: @code{#t})
+This Boolean indicates whether the file system needs to be checked for
+errors before being mounted.
+
+@item @code{create-mount-point?} (default: @code{#f})
+When true, the mount point is created if it does not exist yet.
+

+This is a list of @code{<file-system>} or @code{<mapped-device>} objects
+representing file systems that must be mounted or mapped devices that must
+be opened before (and unmounted or closed after) this one.
+
+As an example, consider a hierarchy of mounts: @file{/sys/fs/cgroup} is a
+dependency of @file{/sys/fs/cgroup/cpu} and @file{/sys/fs/cgroup/memory}.
+
+Another example is a file system that depends on a mapped device, for

+@cindex device mapping
+@cindex mapped devices
+The Linux kernel has a notion of @dfn{device mapping}: a block device, such
+as a hard disk partition, can be @dfn{mapped} into another device, usually
+in @code{/dev/mapper/}, with additional processing over the data that flows
+through it@footnote{Note that the GNU@tie{}Hurd makes no difference between
+the concept of a ``mapped device'' and that of a file system: both boil down
+to @emph{translating} input/output operations made on a file to operations
+on its backing store.  Thus, the Hurd implements mapped devices, like file
+systems, using the generic @dfn{translator} mechanism (@pxref{Translators,,,
+hurd, The GNU Hurd Reference Manual}).}.  A typical example is encryption
+device mapping: all writes to the mapped device are encrypted, and all reads
+are deciphered, transparently.  Guix extends this notion by considering any
+device or set of devices that are @dfn{transformed} in some way to create a
+new device; for instance, RAID devices are obtained by @dfn{assembling}
+several other devices, such as hard disks or partitions, into a new one that
+behaves as one partition.  Other examples, not yet implemented, are LVM
+logical volumes.
+
+Mapped devices are declared using the @code{mapped-device} form, defined as
+follows; for examples, see below.
+
+@deftp {Data Type} mapped-device
+Objects of this type represent device mappings that will be made when the
+system boots up.
+
+@table @code
+@item source
+This is either a string specifying the name of the block device to be
+mapped, such as @code{"/dev/sda3"}, or a list of such strings when several
+devices need to be assembled for creating a new one.
+
+@item target
+This string specifies the name of the resulting mapped device.  For kernel
+mappers such as encrypted devices of type @code{luks-device-mapping},
+specifying @code{"my-partition"} leads to the creation of the
+@code{"/dev/mapper/my-partition"} device.  For RAID devices of type
+@code{raid-device-mapping}, the full device name such as @code{"/dev/md0"}
+needs to be given.
+
+@item type
+This must be a @code{mapped-device-kind} object, which specifies how
+@var{source} is mapped to @var{target}.
+@end table
+@end deftp
+
+@defvr {Scheme Variable} luks-device-mapping
+This defines LUKS block device encryption using the @command{cryptsetup}
+command from the package with the same name.  It relies on the
+@code{dm-crypt} Linux kernel module.
+@end defvr
+
+@defvr {Scheme Variable} raid-device-mapping
+This defines a RAID device, which is assembled using the @code{mdadm}
+command from the package with the same name.  It requires a Linux kernel
+module for the appropriate RAID level to be loaded, such as @code{raid456}
+for RAID-4, RAID-5 or RAID-6, or @code{raid10} for RAID-10.
+@end defvr
+
+@cindex disk encryption
+@cindex LUKS
+The following example specifies a mapping from @file{/dev/sda3} to
+@file{/dev/mapper/home} using LUKS---the
+@url{https://gitlab.com/cryptsetup/cryptsetup,Linux Unified Key Setup}, a
+standard mechanism for disk encryption.  The @file{/dev/mapper/home} device
+can then be used as the @code{device} of a @code{file-system} declaration
+(@pxref{Dateisysteme}).
+
+@example
+(mapped-device
+  (source "/dev/sda3")
+  (target "home")
+  (type luks-device-mapping))
+@end example
+
+Alternatively, to become independent of device numbering, one may obtain the
+LUKS UUID (@dfn{unique identifier}) of the source device by a command like:
+
+@example
+cryptsetup luksUUID /dev/sda3
+@end example
+
+and use it as follows:
+
+@example
+(mapped-device
+  (source (uuid "cb67fc72-0d54-4c88-9d4b-b225f30b0f44"))
+  (target "home")
+  (type luks-device-mapping))
+@end example
+
+@cindex swap encryption
+It is also desirable to encrypt swap space, since swap space may contain
+sensitive data.  One way to accomplish that is to use a swap file in a file
+system on a device mapped via LUKS encryption.  In this way, the swap file
+is encrypted because the entire device is encrypted.  @xref{Vor der Installation,,Disk Partitioning}, for an example.
+
+A RAID device formed of the partitions @file{/dev/sda1} and @file{/dev/sdb1}
+may be declared as follows:
+
+@example
+(mapped-device
+  (source (list "/dev/sda1" "/dev/sdb1"))
+  (target "/dev/md0")
+  (type raid-device-mapping))
+@end example
+
+The @file{/dev/md0} device can then be used as the @code{device} of a
+@code{file-system} declaration (@pxref{Dateisysteme}).  Note that the RAID
+level need not be given; it is chosen during the initial creation and
+formatting of the RAID device and is determined automatically later.

+@cindex users
+@cindex accounts
+@cindex user accounts
+User accounts and groups are entirely managed through the
+@code{operating-system} declaration.  They are specified with the
+@code{user-account} and @code{user-group} forms:
+
+@example
+(user-account

+  (comment "Bob's sister")
+  (home-directory "/home/alice"))
+@end example
+
+When booting or upon completion of @command{guix system reconfigure}, the
+system ensures that only the user accounts and groups specified in the
+@code{operating-system} declaration exist, and with the specified
+properties.  Thus, account or group creations or modifications made by
+directly invoking commands such as @command{useradd} are lost upon
+reconfiguration or reboot.  This ensures that the system remains exactly as
+declared.
+
+@deftp {Data Type} user-account
+Objects of this type represent user accounts.  The following members may be
+specified:
+
+@table @asis
+@item @code{name}
+The name of the user account.
+
+@item @code{group}
+@cindex groups
+This is the name (a string) or identifier (a number) of the user group this
+account belongs to.
+
+@item @code{supplementary-groups} (default: @code{'()})
+Optionally, this can be defined as a list of group names that this account
+belongs to.
+
+@item @code{uid} (default: @code{#f})
+This is the user ID for this account (a number), or @code{#f}.  In the
+latter case, a number is automatically chosen by the system when the account
+is created.
+
+@item @code{comment} (default: @code{""})
+A comment about the account, such as the account owner's full name.
+
+@item @code{home-directory}
+This is the name of the home directory for the account.
+
+@item @code{create-home-directory?} (default: @code{#t})
+Indicates whether the home directory of this account should be created if it
+does not exist yet.
+
+@item @code{shell} (default: Bash)
+This is a G-expression denoting the file name of a program to be used as the
+shell (@pxref{G-Ausdrücke}).
+
+@item @code{system?} (default: @code{#f})
+This Boolean value indicates whether the account is a ``system'' account.
+System accounts are sometimes treated specially; for instance, graphical
+login managers do not list them.
+
+@anchor{user-account-password}
+@item @code{password} (default: @code{#f})
+You would normally leave this field to @code{#f}, initialize user passwords
+as @code{root} with the @command{passwd} command, and then let users change
+it with @command{passwd}.  Passwords set with @command{passwd} are of course
+preserved across reboot and reconfiguration.
+
+If you @emph{do} want to have a preset password for an account, then this
+field must contain the encrypted password, as a string.  @xref{crypt,,,

+@item @code{name}
+The name of the group.
+
+@item @code{id} (default: @code{#f})
+The group identifier (a number).  If @code{#f}, a new number is

+
+@item @code{system?} (default: @code{#f})
+This Boolean value indicates whether the group is a ``system'' group.
+System groups have low numerical IDs.
+
+@item @code{password} (default: @code{#f})
+What, user groups can have a password? Well, apparently yes.  Unless
+@code{#f}, this field specifies the password of the group.
+
+@end table

+
+For convenience, a variable lists all the basic user groups one may expect:

+@node Locales
+@subsection Locales
+
+@cindex locale
+A @dfn{locale} defines cultural conventions for a particular language and
+region of the world (@pxref{Locales,,, libc, The GNU C Library Reference
+Manual}).  Each locale has a name that typically has the form
+@code{@var{language}_@var{territory}.@var{codeset}}---e.g.,
+@code{fr_LU.utf8} designates the locale for the French language, with
+cultural conventions from Luxembourg, and using the UTF-8 encoding.
+
+@cindex locale definition
+Usually, you will want to specify the default locale for the machine using
+the @code{locale} field of the @code{operating-system} declaration
+(@pxref{„operating-system“-Referenz, @code{locale}}).
+
+The selected locale is automatically added to the @dfn{locale definitions}
+known to the system if needed, with its codeset inferred from its
+name---e.g., @code{bo_CN.utf8} will be assumed to use the @code{UTF-8}
+codeset.  Additional locale definitions can be specified in the
+@code{locale-definitions} slot of @code{operating-system}---this is useful,
+for instance, if the codeset could not be inferred from the locale name.
+The default set of locale definitions includes some widely used locales, but
+not all the available locales, in order to save space.
+
+For instance, to add the North Frisian locale for Germany, the value of that
+field may be:
+
+@example
+(cons (locale-definition
+        (name "fy_DE.utf8") (source "fy_DE"))
+      %default-locale-definitions)
+@end example
+
+Likewise, to save space, one might want @code{locale-definitions} to list
+only the locales that are actually used, as in:
+
+@example
+(list (locale-definition
+        (name "ja_JP.eucjp") (source "ja_JP")
+        (charset "EUC-JP")))
+@end example
+
+@vindex LOCPATH
+The compiled locale definitions are available at
+@file{/run/current-system/locale/X.Y}, where @code{X.Y} is the libc version,
+which is the default location where the GNU@tie{}libc provided by Guix looks
+for locale data.  This can be overridden using the @code{LOCPATH}
+environment variable (@pxref{locales-and-locpath, @code{LOCPATH} and locale
+packages}).
+
+The @code{locale-definition} form is provided by the @code{(gnu system
+locale)} module.  Details are given below.
+
+@deftp {Data Type} locale-definition
+This is the data type of a locale definition.
+
+@table @asis
+
+@item @code{name}
+The name of the locale.  @xref{Locale Names,,, libc, The GNU C Library
+Reference Manual}, for more information on locale names.
+
+@item @code{source}
+The name of the source for that locale.  This is typically the
+@code{@var{language}_@var{territory}} part of the locale name.
+
+@item @code{charset} (default: @code{"UTF-8"})
+The ``character set'' or ``code set'' for that locale,
+@uref{http://www.iana.org/assignments/character-sets, as defined by IANA}.
+
+@end table
+@end deftp
+
+@defvr {Scheme Variable} %default-locale-definitions
+A list of commonly used UTF-8 locales, used as the default value of the
+@code{locale-definitions} field of @code{operating-system} declarations.
+
+@cindex locale name
+@cindex normalized codeset in locale names
+These locale definitions use the @dfn{normalized codeset} for the part that
+follows the dot in the name (@pxref{Using gettextized software, normalized
+codeset,, libc, The GNU C Library Reference Manual}).  So for instance it
+has @code{uk_UA.utf8} but @emph{not}, say, @code{uk_UA.UTF-8}.
+@end defvr
+
+@subsubsection Locale Data Compatibility Considerations
+
+@cindex incompatibility, of locale data
+@code{operating-system} declarations provide a @code{locale-libcs} field to
+specify the GNU@tie{}libc packages that are used to compile locale
+declarations (@pxref{„operating-system“-Referenz}).  ``Why would I care?'',
+you may ask.  Well, it turns out that the binary format of locale data is
+occasionally incompatible from one libc version to another.
+
+@c See <https://sourceware.org/ml/libc-alpha/2015-09/msg00575.html>
+@c and <https://lists.gnu.org/archive/html/guix-devel/2015-08/msg00737.html>.
+For instance, a program linked against libc version 2.21 is unable to read
+locale data produced with libc 2.22; worse, that program @emph{aborts}
+instead of simply ignoring the incompatible locale data@footnote{Versions
+2.23 and later of GNU@tie{}libc will simply skip the incompatible locale
+data, which is already an improvement.}.  Similarly, a program linked
+against libc 2.22 can read most, but not all, of the locale data from libc
+2.21 (specifically, @code{LC_COLLATE} data is incompatible); thus calls to
+@code{setlocale} may fail, but programs will not abort.
+
+The ``problem'' in GuixSD is that users have a lot of freedom: They can
+choose whether and when to upgrade software in their profiles, and might be
+using a libc version different from the one the system administrator used to
+build the system-wide locale data.
+
+Fortunately, unprivileged users can also install their own locale data and
+define @var{GUIX_LOCPATH} accordingly (@pxref{locales-and-locpath,
+@code{GUIX_LOCPATH} and locale packages}).
+
+Still, it is best if the system-wide locale data at
+@file{/run/current-system/locale} is built for all the libc versions
+actually in use on the system, so that all the programs can access it---this
+is especially crucial on a multi-user system.  To do that, the administrator
+can specify several libc packages in the @code{locale-libcs} field of
+@code{operating-system}:
+
+@example
+(use-package-modules base)
+
+(operating-system
+  ;; @dots{}
+  (locale-libcs (list glibc-2.21 (canonical-package glibc))))
+@end example
+
+This example would lead to a system containing locale definitions for both
+libc 2.21 and the current version of libc in
+@file{/run/current-system/locale}.
+
+
+@node Dienste
+@subsection Dienste
+
+@cindex system services
+An important part of preparing an @code{operating-system} declaration is
+listing @dfn{system services} and their configuration (@pxref{Das Konfigurationssystem nutzen}).  System services are typically daemons launched when
+the system boots, or other actions needed at that time---e.g., configuring
+network access.
+
+GuixSD has a broad definition of ``service'' (@pxref{Dienstkompositionen}),
+but many services are managed by the GNU@tie{}Shepherd (@pxref{Shepherd-Dienste}).  On a running system, the @command{herd} command allows you to
+list the available services, show their status, start and stop them, or do
+other specific operations (@pxref{Jump Start,,, shepherd, The GNU Shepherd
+Manual}).  For example:
+
+@example
+# herd status
+@end example
+
+The above command, run as @code{root}, lists the currently defined
+services.  The @command{herd doc} command shows a synopsis of the given
+service and its associated actions:
+
+@example
+# herd doc nscd
+Run libc's name service cache daemon (nscd).
+
+# herd doc nscd action invalidate
+invalidate: Invalidate the given cache--e.g., 'hosts' for host name lookups.
+@end example
+
+The @command{start}, @command{stop}, and @command{restart} sub-commands have
+the effect you would expect.  For instance, the commands below stop the nscd
+service and restart the Xorg display server:
+
+@example
+# herd stop nscd
+Service nscd has been stopped.
+# herd restart xorg-server
+Service xorg-server has been stopped.
+Service xorg-server has been started.
+@end example
+
+The following sections document the available services, starting with the
+core services, that may be used in an @code{operating-system} declaration.

+@subsubsection Basisdienste
+
+The @code{(gnu services base)} module provides definitions for the basic
+services that one expects from the system.  The services exported by this
+module are listed below.
+
+@defvr {Scheme Variable} %base-services
+This variable contains a list of basic services (@pxref{Diensttypen und Dienste}, for more information on service objects) one would expect from
+the system: a login service (mingetty) on each tty, syslogd, the libc name
+service cache daemon (nscd), the udev device manager, and more.
+
+This is the default value of the @code{services} field of
+@code{operating-system} declarations.  Usually, when customizing a system,
+you will want to append services to @var{%base-services}, like this:
+
+@example
+(cons* (avahi-service) (lsh-service) %base-services)
+@end example
+@end defvr
+
+@defvr {Scheme Variable} special-files-service-type
+This is the service that sets up ``special files'' such as @file{/bin/sh};
+an instance of it is part of @code{%base-services}.
+
+The value associated with @code{special-files-service-type} services must be
+a list of tuples where the first element is the ``special file'' and the
+second element is its target.  By default it is:
+
+@cindex @file{/bin/sh}
+@cindex @file{sh}, in @file{/bin}
+@example
+`(("/bin/sh" ,(file-append @var{bash} "/bin/sh")))
+@end example
+
+@cindex @file{/usr/bin/env}
+@cindex @file{env}, in @file{/usr/bin}
+If you want to add, say, @code{/usr/bin/env} to your system, you can change
+it to:
+
+@example
+`(("/bin/sh" ,(file-append @var{bash} "/bin/sh"))
+  ("/usr/bin/env" ,(file-append @var{coreutils} "/bin/env")))
+@end example
+
+Since this is part of @code{%base-services}, you can use
+@code{modify-services} to customize the set of special files (@pxref{Service-Referenz, @code{modify-services}}).  But the simple way to add a special
+file is @i{via} the @code{extra-special-file} procedure (see below.)
+@end defvr
+
+@deffn {Scheme Procedure} extra-special-file @var{file} @var{target}
+Use @var{target} as the ``special file'' @var{file}.
+
+For example, adding the following lines to the @code{services} field of your
+operating system declaration leads to a @file{/usr/bin/env} symlink:
+
+@example
+(extra-special-file "/usr/bin/env"
+                    (file-append coreutils "/bin/env"))
+@end example
+@end deffn

+the status messages produced by certain types of modems.
+
+@item @code{skip-login?} (default: @code{#f})
+When set to @code{#t}, do not prompt the user for a login name.  This can be

+from @var{baud-rate} are used when agetty receives a @key{BREAK} character.
+
+@item @code{timeout} (default: @code{#f})
+When set to an integer value, terminate if no user name could be read within
+@var{timeout} seconds.
+
+@item @code{detect-case?} (default: @code{#f})
+When set to @code{#t}, turn on support for detecting an uppercase-only
+terminal.  This setting will detect a login name containing only uppercase
+letters as indicating an uppercase-only terminal and turn on some
+upper-to-lower case conversions.  Note that this will not support Unicode
+characters.
+
+@item @code{wait-cr?} (default: @code{#f})

+
+@item @code{kill-characters} (default: @code{#f})
+This option accepts a string that should be interpreted to mean "ignore all
+previous characters" (also called a "kill" character) when the types their
+login name.
+
+@item @code{chdir} (default: @code{#f})
+This option accepts, as a string, a directory path that will be changed to
+before login.

+@cindex X Window System
+@cindex login manager
+Support for the X Window graphical display system---specifically Xorg---is
+provided by the @code{(gnu services xorg)} module.  Note that there is no
+@code{xorg-service} procedure.  Instead, the X server is started by the
+@dfn{login manager}, by default SLiM.
+
+@cindex window manager
+To use X11, you must install at least one @dfn{window manager}---for example
+the @code{windowmaker} or @code{openbox} packages---preferably by adding it
+to the @code{packages} field of your operating system definition
+(@pxref{„operating-system“-Referenz, system-wide packages}).
+
+@defvr {Scheme Variable} slim-service-type
+This is the type for the SLiM graphical login manager for X11.
+
+@cindex session types (X11)
+@cindex X11 session types
+SLiM looks for @dfn{session types} described by the @file{.desktop} files in
+@file{/run/current-system/profile/share/xsessions} and allows users to
+choose a session from the log-in screen using @kbd{F1}.  Packages such as
+@code{xfce}, @code{sawfish}, and @code{ratpoison} provide @file{.desktop}
+files; adding them to the system-wide set of packages automatically makes
+them available at the log-in screen.
+
+In addition, @file{~/.xsession} files are honored.  When available,
+@file{~/.xsession} must be an executable that starts a window manager and/or
+other X clients.

+@var{xorg-server}] Return a @code{startx} script in which @var{modules}, a
+list of X module packages, and @var{fonts}, a list of X font directories,
+are available.  See @code{xorg-wrapper} for more details on the arguments.
+The result should be used in place of @code{startx}.

+
+@var{modules} must be a list of @dfn{module packages} loaded by the Xorg
+server---e.g., @code{xf86-video-vesa}, @code{xf86-input-keyboard}, and so
+on.  @var{fonts} must be a list of font directories to add to the server's
+@dfn{font path}.
+
+@var{drivers} must be either the empty list, in which case Xorg chooses a
+graphics driver automatically, or a list of driver names that will be tried
+in this order---e.g., @code{("modesetting" "vesa")}.
+
+Likewise, when @var{resolutions} is the empty list, Xorg chooses an
+appropriate screen resolution; otherwise, it must be a list of
+resolutions---e.g., @code{((1024 768) (640 480))}.
+
+Last, @var{extra-config} is a list of strings or objects appended to the
+configuration file.  It is used to pass extra text to be added verbatim to
+the configuration file.
+
+@cindex keymap
+@cindex keyboard layout
+This procedure is especially useful to configure a different keyboard layout
+than the default US keymap.  For instance, to use the ``bépo'' keymap by

+
+@example
+(define bepo-evdev
+  "Section \"InputClass\"
+        Identifier \"evdev keyboard catchall\"
+        Driver \"evdev\"
+        MatchIsKeyboard \"on\"
+        Option \"xkb_layout\" \"fr\"

+                     #:extra-config
+                     (list bepo-evdev)))))))))
+@end example
+
+The @code{MatchIsKeyboard} line specifies that we only apply the
+configuration to keyboards.  Without this line, other devices such as
+touchpad may not work correctly because they will be attached to the wrong
+driver.  In this example, the user typically used @code{setxkbmap fr bepo}
+to set their favorite keymap once logged in.  The first argument corresponds
+to the layout, while the second argument corresponds to the variant.  The
+@code{xkb_variant} line can be omitted to select the default variant.

+@cindex printer support with CUPS
+The @code{(gnu services cups)} module provides a Guix service definition for
+the CUPS printing service.  To add printer support to a GuixSD system, add a
+@code{cups-service} to the operating system definition:
+
+@deffn {Scheme Variable} cups-service-type
+The service type for the CUPS print server.  Its value should be a valid
+CUPS configuration (see below).  To use the default settings, simply write:
+@example
+(service cups-service-type)
+@end example
+@end deffn
+
+The CUPS configuration controls the basic things about your CUPS
+installation: what interfaces it listens on, what to do if a print job
+fails, how much logging to do, and so on.  To actually add a printer, you
+have to visit the @url{http://localhost:631} URL, or use a tool such as
+GNOME's printer configuration services.  By default, configuring a CUPS
+service will generate a self-signed certificate if needed, for secure
+connections to the print server.
+
+Suppose you want to enable the Web interface of CUPS and also add support
+for Epson printers @i{via} the @code{escpr} package and for HP printers
+@i{via} the @code{hplip-minimal} package.  You can do that directly, like
+this (you need to use the @code{(gnu packages cups)} module):
+
+@example
+(service cups-service-type
+         (cups-configuration
+           (web-interface? #t)
+           (extensions
+             (list cups-filters escpr hplip-minimal))))
+@end example
+
+Note: If you wish to use the Qt5 based GUI which comes with the hplip
+package then it is suggested that you install the @code{hplip} package,
+either in your OS configuration file or as your user.
+
+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  There is
+also a way to specify the configuration as a string, if you have an old
+@code{cupsd.conf} file that you want to port over from some other system;
+see the end for more details.
+
+@c The following documentation was initially generated by
+@c (generate-documentation) in (gnu services cups).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change

+At this point you're probably thinking ``oh dear, Guix manual, I like you
+but you can stop already with the configuration options''.  Indeed.
+However, one more point: it could be that you have an existing

+@code{opaque-cups-configuration} as the configuration of a
+@code{cups-service-type}.

+@node Desktop-Dienste
+@subsubsection Desktop-Dienste
+
+The @code{(gnu services desktop)} module provides services that are usually
+useful in the context of a ``desktop'' setup---that is, on a machine running
+a graphical display server, possibly with graphical user interfaces, etc.
+It also defines services that provide specific desktop environments like
+GNOME, XFCE or MATE.
+
+To simplify things, the module defines a variable containing the set of
+services that users typically expect on a machine with a graphical
+environment and networking:
+
+@defvr {Scheme Variable} %desktop-services
+This is a list of services that builds upon @var{%base-services} and adds or
+adjusts services for a typical ``desktop'' setup.
+
+In particular, it adds a graphical login manager (@pxref{X Window,
+@code{slim-service}}), screen lockers, a network management tool
+(@pxref{Netzwerkdienste, @code{network-manager-service-type}}), energy
+and color management services, the @code{elogind} login and seat manager,
+the Polkit privilege service, the GeoClue location service, the
+AccountsService daemon that allows authorized users change system passwords,
+an NTP client (@pxref{Netzwerkdienste}), the Avahi daemon, and has the
+name service switch service configured to be able to use @code{nss-mdns}
+(@pxref{Name Service Switch, mDNS}).
+@end defvr
+
+The @var{%desktop-services} variable can be used as the @code{services}
+field of an @code{operating-system} declaration (@pxref{„operating-system“-Referenz, @code{services}}).
+
+Additionally, the @code{gnome-desktop-service}, @code{xfce-desktop-service},
+@code{mate-desktop-service} and @code{enlightenment-desktop-service-type}
+procedures can add GNOME, XFCE, MATE and/or Enlightenment to a system.  To
+``add GNOME'' means that system-level services like the backlight adjustment
+helpers and the power management utilities are added to the system,
+extending @code{polkit} and @code{dbus} appropriately, allowing GNOME to
+operate with elevated privileges on a limited number of special-purpose
+system interfaces.  Additionally, adding a service made by
+@code{gnome-desktop-service} adds the GNOME metapackage to the system
+profile.  Likewise, adding the XFCE service not only adds the @code{xfce}
+metapackage to the system profile, but it also gives the Thunar file manager
+the ability to open a ``root-mode'' file management window, if the user
+authenticates using the administrator's password via the standard polkit
+graphical interface.  To ``add MATE'' means that @code{polkit} and
+@code{dbus} are extended appropriately, allowing MATE to operate with
+elevated privileges on a limited number of special-purpose system
+interfaces.  Additionally, adding a service made by
+@code{mate-desktop-service} adds the MATE metapackage to the system
+profile.  ``Adding ENLIGHTENMENT'' means that @code{dbus} is extended
+appropriately, and several of Enlightenment's binaries are set as setuid,
+allowing Enlightenment's screen locker and other functionality to work as
+expetected.
+
+The desktop environments in Guix use the Xorg display server by default.  If
+you'd like to use the newer display server protocol called Wayland, you need
+to use the @code{sddm-service} instead of the @code{slim-service} for the
+graphical login manager.  You should then select the ``GNOME (Wayland)''
+session in SDDM.  Alternatively you can also try starting GNOME on Wayland
+manually from a TTY with the command ``XDG_SESSION_TYPE=wayland exec
+dbus-run-session gnome-session``.  Currently only GNOME has support for
+Wayland.
+
+@deffn {Scheme Procedure} gnome-desktop-service
+Return a service that adds the @code{gnome} package to the system profile,
+and extends polkit with the actions from @code{gnome-settings-daemon}.
+@end deffn
+
+@deffn {Scheme Procedure} xfce-desktop-service
+Return a service that adds the @code{xfce} package to the system profile,
+and extends polkit with the ability for @code{thunar} to manipulate the file
+system as root from within a user session, after the user has authenticated
+with the administrator's password.
+@end deffn
+
+@deffn {Scheme Procedure} mate-desktop-service
+Return a service that adds the @code{mate} package to the system profile,
+and extends polkit with the actions from @code{mate-settings-daemon}.
+@end deffn
+
+@deffn {Scheme Procedure} enlightenment-desktop-service-type
+Return a service that adds the @code{enlightenment} package to the system
+profile, and extends dbus with actions from @code{efl}.
+@end deffn
+
+@deftp {Data Type} enlightenment-desktop-service-configuration
+@table @asis
+@item @code{enlightenment} (default @code{enlightenment})
+The enlightenment package to use.
+@end table
+@end deftp
+
+Because the GNOME, XFCE and MATE desktop services pull in so many packages,
+the default @code{%desktop-services} variable doesn't include any of them by
+default.  To add GNOME, XFCE or MATE, just @code{cons} them onto
+@code{%desktop-services} in the @code{services} field of your
+@code{operating-system}:
+
+@example
+(use-modules (gnu))
+(use-service-modules desktop)
+(operating-system
+  ...
+  ;; cons* adds items to the list given as its last argument.
+  (services (cons* (gnome-desktop-service)
+                   (xfce-desktop-service)
+                   %desktop-services))
+  ...)
+@end example
+
+These desktop environments will then be available as options in the
+graphical login window.
+
+The actual service definitions included in @code{%desktop-services} and
+provided by @code{(gnu services dbus)} and @code{(gnu services desktop)} are
+described below.
+
+@deffn {Scheme Procedure} dbus-service [#:dbus @var{dbus}] [#:services '()]
+Return a service that runs the ``system bus'', using @var{dbus}, with
+support for @var{services}.
+
+@uref{http://dbus.freedesktop.org/, D-Bus} is an inter-process communication
+facility.  Its system bus is used to allow system services to communicate
+and to be notified of system-wide events.
+
+@var{services} must be a list of packages that provide an
+@file{etc/dbus-1/system.d} directory containing additional D-Bus
+configuration and policy files.  For example, to allow avahi-daemon to use
+the system bus, @var{services} must be equal to @code{(list avahi)}.
+@end deffn
+
+@deffn {Scheme Procedure} elogind-service [#:config @var{config}]
+Return a service that runs the @code{elogind} login and seat management
+daemon.  @uref{https://github.com/elogind/elogind, Elogind} exposes a D-Bus
+interface that can be used to know which users are logged in, know what kind
+of sessions they have open, suspend the system, inhibit system suspend,
+reboot the system, and other tasks.
+
+Elogind handles most system-level power events for a computer, for example
+suspending the system when a lid is closed, or shutting it down when the
+power button is pressed.
+
+The @var{config} keyword argument specifies the configuration for elogind,
+and should be the result of an @code{(elogind-configuration (@var{parameter}
+@var{value})...)} invocation.  Available parameters and their default values
+are:

+@node Mail-Dienste
+@subsubsection Mail-Dienste
+
+@cindex mail
+@cindex email
+The @code{(gnu services mail)} module provides Guix service definitions for
+email services: IMAP, POP3, and LMTP servers, as well as mail transport
+agents (MTAs).  Lots of acronyms! These services are detailed in the
+subsections below.
+
+@subsubheading Dovecot Service
+
+@deffn {Scheme Procedure} dovecot-service [#:config (dovecot-configuration)]
+Return a service that runs the Dovecot IMAP/POP3/LMTP mail server.
+@end deffn
+
+By default, Dovecot does not need much configuration; the default
+configuration object created by @code{(dovecot-configuration)} will suffice
+if your mail is delivered to @code{~/Maildir}.  A self-signed certificate
+will be generated for TLS-protected connections, though Dovecot will also
+listen on cleartext ports by default.  There are a number of options,
+though, which mail administrators might need to change, and as is the case
+with other services, Guix allows the system administrator to specify these
+parameters via a uniform Scheme interface.
+
+For example, to specify that mail is located at @code{maildir~/.mail}, one
+would instantiate the Dovecot service like this:
+
+@example
+(dovecot-service #:config
+                 (dovecot-configuration
+                  (mail-location "maildir:~/.mail")))
+@end example
+
+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  There is
+also a way to specify the configuration as a string, if you have an old
+@code{dovecot.conf} file that you want to port over from some other system;
+see the end for more details.
+
+@c The following documentation was initially generated by
+@c (generate-documentation) in (gnu services mail).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as dovecot updates.

+
+@deftypevr {@code{mailbox-configuration} parameter} space-separated-string-list special-use
+List of IMAP @code{SPECIAL-USE} attributes as specified by RFC 6154.  Valid

+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list login-trusted-networks
+List of trusted network ranges.  Connections from these IPs are allowed to
+override their IP addresses and ports (for logging and for authentication
+checks).  @samp{disable-plaintext-auth} is also ignored for these networks.
+Typically you would specify your IMAP proxy servers here.  Defaults to
+@samp{()}.

+List of login access check sockets (e.g.@: tcpwrap).  Defaults to @samp{()}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean verbose-proctitle?
+Show more verbose process titles (in ps).  Currently shows user name and IP
+address.  Useful for seeing who is actually using the IMAP processes (e.g.@:
+shared mailboxes or if the same uid is used for multiple accounts).
+Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean shutdown-clients?
+Should all processes be killed when Dovecot master process shuts down.
+Setting this to @code{#f} means that Dovecot can be upgraded without forcing
+existing client connections to close (although that could also be a problem
+if the upgrade is e.g.@: due to a security fix).  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer doveadm-worker-count
+If non-zero, run mail commands via this many connections to doveadm server,
+instead of running them directly in the same process.  Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string doveadm-socket-path
+UNIX socket or host:port used for connecting to doveadm server.  Defaults to

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean disable-plaintext-auth?
+Disable LOGIN command and all other plaintext authentications unless SSL/TLS
+is used (LOGINDISABLED capability).  Note that if the remote IP matches the
+local IP (i.e.@: you're connecting from the same computer), the connection
+is considered secure and plaintext authentication is allowed.  See also
+ssl=required setting.  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer auth-cache-size
+Authentication cache size (e.g.@: @samp{#e10e6}).  0 means it's disabled.
+Note that bsdauth, PAM and vpopmail require @samp{cache-key} to be set for
+caching to be used.  Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-cache-ttl
+Time to live for cached data.  After TTL expires the cached record is no
+longer used, *except* if the main database lookup returns internal failure.
+We also try to handle password changes automatically: If user's previous
+authentication was successful, but this one wasn't, the cache isn't used.
+For now this works only with plaintext authentication.  Defaults to @samp{"1
+hour"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-cache-negative-ttl
+TTL for negative hits (user not found, password mismatch).  0 disables

+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list auth-realms
+List of realms for SASL authentication mechanisms that need them.  You can
+leave it empty if you don't want to support multiple realms.  Many clients

+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-default-realm
+Default realm/domain to use if none was specified.  This is used for both

+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-chars
+List of allowed characters in username.  If the user-given username contains
+a character not listed in here, the login automatically fails.  This is just
+an extra check to make sure user can't exploit any potential quote escaping
+vulnerabilities with SQL/LDAP databases.  If you want to allow all
+characters, set this value to empty.  Defaults to
+@samp{"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@@"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-translation
+Username character translations before it's looked up from databases.  The
+value contains series of from -> to characters.  For example @samp{#@@/@@}

+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-format
+Username formatting before it's looked up from databases.  You can use the
+standard variables here, e.g.@: %Lu would lowercase the username, %n would
+drop away the domain if it was given, or @samp{%n-AT-%d} would change the
+@samp{@@} into @samp{-AT-}.  This translation is done after

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-master-user-separator
+If you want to allow master users to log in by specifying the master
+username within the normal username string (i.e.@: not using SASL
+mechanism's support for it), you can specify the separator character here.
+The format is then <username><separator><master username>.  UW-IMAP uses
+@samp{*} as the separator, so that could be a good choice.  Defaults to
+@samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-anonymous-username
+Username to use for users logging in with ANONYMOUS SASL mechanism.
+Defaults to @samp{"anonymous"}.

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-gssapi-hostname
+Host name to use in GSSAPI principal names.  The default is to use the name

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-krb5-keytab
+Kerberos keytab to use for the GSSAPI mechanism.  Will use the system

+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list director-servers
+List of IPs or hostnames to all director servers, including ourself.  Ports

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string director-username-hash
+How the username is translated before being hashed.  Useful values include
+%Ln if user can log in with or without @@domain, %Ld if mailboxes are shared

+
+@deftypevr {@code{dovecot-configuration} parameter} string syslog-facility
+Syslog facility to use if you're logging to syslog.  Usually if you don't

+Log unsuccessful authentication attempts and the reasons why they failed.
+Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean auth-verbose-passwords?
+In case of password mismatches, log the attempted password.  Valid values
+are no, plain and sha1.  sha1 can be useful for detecting brute force
+password attempts vs.  user simply trying the same password over and over
+again.  You can also truncate the value to n chars by appending ":n" (e.g.@:
+sha1:6).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean auth-debug?
+Even more verbose logging for debugging purposes.  Shows for example SQL

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean auth-debug-passwords?
+In case of password mismatches, log the passwords and used scheme so the

+Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-debug?
+Enable mail process debugging.  This can help you figure out why Dovecot
+isn't finding your mails.  Defaults to @samp{#f}.

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string login-log-format
+Login log format.  %s contains @samp{login-log-format-elements} string, %$

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-log-prefix
+Log prefix for mail processes.  See doc/wiki/Variables.txt for list of

+@samp{"\"%s(%u)<%@{pid@}><%@{session@}>: \""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string deliver-log-format
+Format to use for logging mail deliveries.  You can use variables:
+@table @code
+@item %$
+Delivery status message (e.g.@: @samp{saved to INBOX})
+@item %m
+Message-ID
+@item %s
+Subject
+@item %f
+From address
+@item %p
+Physical size
+@item %w
+Virtual size.
+@end table
+Defaults to @samp{"msgid=%m: %$"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-location
+Location for users' mailboxes.  The default is empty, which means that
+Dovecot tries to find the mailboxes automatically.  This won't work if the
+user doesn't yet have any mail, so you should explicitly tell Dovecot the
+full location.
+
+If you're using mbox, giving a path to the INBOX file (e.g.@: /var/mail/%u)
+isn't enough.  You'll also need to tell Dovecot where the other mailboxes
+are kept.  This is called the "root mail directory", and it must be the
+first path given in the @samp{mail-location} setting.
+
+There are a few special variables you can use, eg.:
+
+@table @samp
+@item %u
+username
+@item %n
+user part in user@@domain, same as %u if there's no domain
+@item %d
+domain part in user@@domain, empty if there's no domain
+@item %h
+home director
+@end table
+
+See doc/wiki/Variables.txt for full list.  Some examples:

+@end table
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-uid
+System user and group used to access mails.  If you use multiple, userdb can
+override these by returning uid or gid fields.  You can use either numbers
+or names.  <doc/wiki/UserIds.txt>.  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-gid
+
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-privileged-group
+Group to enable temporarily for privileged operations.  Currently this is
+used only with INBOX when either its initial creation or dotlocking fails.
+Typically this is set to "mail" to give access to /var/mail.  Defaults to
+@samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-access-groups
+Grant access to these supplementary groups for mail processes.  Typically
+these are used to set up access to shared mailboxes.  Note that it may be
+dangerous to set these if users can create symlinks (e.g.@: if "mail" group
+is set here, ln -s /var/mail ~/mail/var could allow a user to delete others'
+mailboxes, or ln -s /secret/shared/box ~/mail/mybox would allow reading
+it).  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-full-filesystem-access?
+Allow full file system access to clients.  There's no access checks other
+than what the operating system does for the active UID/GID.  It works with
+both maildir and mboxes, allowing you to prefix mailboxes names with e.g.@:
+/path/ or ~user/.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mmap-disable?
+Don't use mmap() at all.  This is required if you store indexes to shared
+file systems (NFS or clustered file system).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean dotlock-use-excl?
+Rely on @samp{O_EXCL} to work when creating dotlock files.  NFS supports
+@samp{O_EXCL} since version 3, so this should be safe to use nowadays by
+default.  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-fsync
+When to use fsync() or fdatasync() calls:
+@table @code
+@item optimized
+Whenever necessary to avoid losing important data
+@item always
+Useful with e.g.@: NFS when write()s are delayed
+@item never
+Never use it (best performance, but crashes can lose data).
+@end table
+Defaults to @samp{"optimized"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-nfs-storage?
+Mail storage exists in NFS.  Set this to yes to make Dovecot flush NFS
+caches whenever needed.  If you're using only a single mail server this
+isn't needed.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-nfs-index?
+Mail index files also exist in NFS.  Setting this to yes requires
+@samp{mmap-disable? #t} and @samp{fsync-disable? #f}.  Defaults to
+@samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string lock-method
+Locking method for index files.  Alternatives are fcntl, flock and dotlock.
+Dotlocking uses some tricks which may create more disk I/O than other
+locking methods.  NFS users: flock doesn't work, remember to change
+@samp{mmap-disable}.  Defaults to @samp{"fcntl"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name mail-temp-dir
+Directory in which LDA/LMTP temporarily stores incoming mails >128 kB.
+Defaults to @samp{"/tmp"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer first-valid-uid
+Valid UID range for users.  This is mostly to make sure that users can't log
+in as daemons or other system users.  Note that denying root logins is
+hardcoded to dovecot binary and can't be done even if @samp{first-valid-uid}
+is set to 0.  Defaults to @samp{500}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer last-valid-uid
+
+Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer first-valid-gid
+Valid GID range for users.  Users having non-valid GID as primary group ID
+aren't allowed to log in.  If user belongs to supplementary groups with
+non-valid GIDs, those groups are not set.  Defaults to @samp{1}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer last-valid-gid
+
+Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mail-max-keyword-length
+Maximum allowed length for mail keyword name.  It's only forced when trying
+to create new keywords.  Defaults to @samp{50}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} colon-separated-file-name-list valid-chroot-dirs
+List of directories under which chrooting is allowed for mail processes
+(i.e.@: /var/mail will allow chrooting to /var/mail/foo/bar too).  This
+setting doesn't affect @samp{login-chroot} @samp{mail-chroot} or auth chroot
+settings.  If this setting is empty, "/./" in home dirs are ignored.
+WARNING: Never add directories here which local users can modify, that may
+lead to root exploit.  Usually this should be done only if you don't allow
+shell access for users.  <doc/wiki/Chrooting.txt>.  Defaults to @samp{()}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-chroot
+Default chroot directory for mail processes.  This can be overridden for
+specific users in user database by giving /./ in user's home directory
+(e.g.@: /home/./user chroots into /home).  Note that usually there is no
+real need to do chrooting, Dovecot doesn't allow users to access files
+outside their mail directory anyway.  If your home directories are prefixed
+with the chroot directory, append "/."@: to @samp{mail-chroot}.
+<doc/wiki/Chrooting.txt>.  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name auth-socket-path
+UNIX socket path to master authentication server to find users.  This is
+used by imap (for shared users) and lda.  Defaults to
+@samp{"/var/run/dovecot/auth-userdb"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name mail-plugin-dir
+Directory where to look up mail plugins.  Defaults to
+@samp{"/usr/lib/dovecot"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list mail-plugins
+List of plugins to load for all services.  Plugins specific to IMAP, LDA,

+@samp{()}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mail-cache-min-mail-count
+The minimum number of mails in a mailbox before updates are done to cache
+file.  This allows optimizing Dovecot's behavior to do less disk writes at
+the cost of more disk reads.  Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mailbox-idle-check-interval
+When IDLE command is running, mailbox is checked once in a while to see if
+there are any new mails or other changes.  This setting defines the minimum
+time to wait between those checks.  Dovecot can also use dnotify, inotify
+and kqueue to find out immediately when changes occur.  Defaults to
+@samp{"30 secs"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-save-crlf?
+Save mails with CR+LF instead of plain LF.  This makes sending those mails
+take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
+But it also creates a bit more disk I/O which may just make it slower.  Also
+note that if other software reads the mboxes/maildirs, they may handle the
+extra CRs wrong and cause problems.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-stat-dirs?
+By default LIST command returns all entries in maildir beginning with a
+dot.  Enabling this option makes Dovecot return only entries which are
+directories.  This is done by stat()ing each entry, so it causes more disk
+I/O.  (For systems setting struct @samp{dirent->d_type} this check is free
+and it's done always regardless of this setting).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-copy-with-hardlinks?
+When copying a message, do it with hard links whenever possible.  This makes
+the performance much better, and it's unlikely to have any side effects.
+Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-very-dirty-syncs?
+Assume Dovecot is the only MUA accessing Maildir: Scan cur/ directory only
+when its mtime changes unexpectedly or when we can't find the mail
+otherwise.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list mbox-read-locks
+Which locking methods to use for locking mbox.  There are four available:
+
+@table @code
+@item dotlock
+Create <mailbox>.lock file.  This is the oldest and most NFS-safe solution.
+If you want to use /var/mail/ like directory, the users will need write

+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mbox-dirty-syncs?
+When mbox changes unexpectedly we have to fully read it to find out what
+changed.  If the mbox is large this can take a long time.  Since the change
+is usually just a newly appended mail, it'd be faster to simply read the new
+mails.  If this setting is enabled, Dovecot does this but still safely
+fallbacks to re-reading the whole mbox file whenever something in mbox isn't
+how it's expected to be.  The only real downside to this setting is that if
+some other MUA changes message flags, Dovecot doesn't notice it
+immediately.  Note that a full sync is done with SELECT, EXAMINE, EXPUNGE

+with this workaround if synchronization is set to "Headers Only".
+
+@item tb-extra-mailbox-sep
+Thunderbird gets somehow confused with LAYOUT=fs (mbox and dbox) and adds

+ignore the extra @samp{/} instead of treating it as invalid mailbox name.
+
+@item tb-lsub-flags
+Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g.@: mbox).  This

+
+
+Whew! Lots of configuration options.  The nice thing about it though is that
+GuixSD has a complete interface to Dovecot's configuration language.  This
+allows not only a nice way to declare configurations, but also offers
+reflective capabilities as well: users can write code to inspect and
+transform configurations from within Scheme.
+
+However, it could be that you just want to get a @code{dovecot.conf} up and
+running.  In that case, you can pass an @code{opaque-dovecot-configuration}
+as the @code{#:config} parameter to @code{dovecot-service}.  As its name
+indicates, an opaque configuration does not have easy reflective
+capabilities.
+
+Available @code{opaque-dovecot-configuration} fields are:

+The dovecot package.
+@end deftypevr
+

+@subsubheading Prosody Service
+
+@deffn {Scheme Variable} prosody-service-type
+This is the type for the @uref{https://prosody.im, Prosody XMPP

+@end example
+
+See below for details about @code{prosody-configuration}.
+
+@end deffn
+
+By default, Prosody does not need much configuration.  Only one
+@code{virtualhosts} field is needed: it specifies the domain you wish
+Prosody to serve.
+
+You can perform various sanity checks on the generated configuration with
+the @code{prosodyctl check} command.
+
+Prosodyctl will also help you to import certificates from the
+@code{letsencrypt} directory so that the @code{prosody} user can access
+them.  See @url{https://prosody.im/doc/letsencrypt}.
+
+@example
+prosodyctl --root cert import /etc/letsencrypt/live
+@end example
+
+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  Types
+starting with @code{maybe-} denote parameters that won't show up in
+@code{prosody.cfg.lua} when their value is @code{'disabled}.
+
+There is also a way to specify the configuration as a string, if you have an
+old @code{prosody.cfg.lua} file that you want to port over from some other
+system; see the end for more details.
+
+The @code{file-object} type designates either a file-like object
+(@pxref{G-Ausdrücke, file-like objects}) or a file name.

+@subsubheading FastCGI
+@cindex fastcgi
+@cindex fcgiwrap
+FastCGI is an interface between the front-end and the back-end of a web
+service.  It is a somewhat legacy facility; new web services should
+generally just talk HTTP between the front-end and the back-end.  However
+there are a number of back-end services such as PHP or the optimized HTTP
+Git repository access that use FastCGI, so we have support for it in Guix.
+
+To use FastCGI, you configure the front-end web server (e.g., nginx) to
+dispatch some subset of its requests to the fastcgi backend, which listens
+on a local TCP or UNIX socket.  There is an intermediary @code{fcgiwrap}
+program that sits between the actual backend process and the web server.
+The front-end indicates which backend program to run, passing that
+information to the @code{fcgiwrap} process.
+
+@defvr {Scheme Variable} fcgiwrap-service-type
+A service type for the @code{fcgiwrap} FastCGI proxy.
+@end defvr
+
+@deftp {Data Type} fcgiwrap-configuration

+The fcgiwrap package to use.
+
+@item @code{socket} (default: @code{tcp:127.0.0.1:9000})
+The socket on which the @code{fcgiwrap} process should listen, as a string.
+Valid @var{socket} values include @code{unix:@var{/path/to/unix/socket}},
+@code{tcp:@var{dot.ted.qu.ad}:@var{port}} and
+@code{tcp6:[@var{ipv6_addr}]:port}.
+
+@item @code{user} (default: @code{fcgiwrap})
+@itemx @code{group} (default: @code{fcgiwrap})
+The user and group names, as strings, under which to run the @code{fcgiwrap}
+process.  The @code{fastcgi} service will ensure that if the user asks for
+the specific user or group names @code{fcgiwrap} that the corresponding user
+and/or group is present on the system.
+
+It is possible to configure a FastCGI-backed web service to pass HTTP
+authentication information from the front-end to the back-end, and to allow
+@code{fcgiwrap} to run the back-end process as a corresponding local user.
+To enable this capability on the back-end., run @code{fcgiwrap} as the
+@code{root} user and group.  Note that this capability also has to be
+configured on the front-end as well.

+
+Thus, make sure to add @code{nss-certs} or another certificate package to

+@cindex HTTP, HTTPS
+@cindex Let's Encrypt
+@cindex TLS certificates
+The @code{(gnu services certbot)} module provides a service to automatically
+obtain a valid TLS certificate from the Let's Encrypt certificate
+authority.  These certificates can then be used to serve content securely
+over HTTPS or other TLS-based protocols, with the knowledge that the client
+will be able to verify the server's authenticity.
+
+@url{https://letsencrypt.org/, Let's Encrypt} provides the @code{certbot}
+tool to automate the certification process.  This tool first securely
+generates a key on the server.  It then makes a request to the Let's Encrypt
+certificate authority (CA) to sign the key.  The CA checks that the request
+originates from the host in question by using a challenge-response protocol,
+requiring the server to provide its response over HTTP.  If that protocol
+completes successfully, the CA signs the key, resulting in a certificate.
+That certificate is valid for a limited period of time, and therefore to
+continue to provide TLS services, the server needs to periodically ask the
+CA to renew its signature.
+
+The certbot service automates this process: the initial key generation, the
+initial certification request to the Let's Encrypt service, the web server
+challenge/response integration, writing the certificate to disk, the
+automated periodic renewals, and the deployment tasks associated with the
+renewal (e.g.@: reloading services, copying keys with different
+permissions).
+
+Certbot is run twice a day, at a random minute within the hour.  It won't do
+anything until your certificates are due for renewal or revoked, but running
+it regularly would give your service a chance of staying online in case a
+Let's Encrypt-initiated revocation happened for some reason.
+
+By using this service, you agree to the ACME Subscriber Agreement, which can
+be found there: @url{https://acme-v01.api.letsencrypt.org/directory}.

+
+The @code{(gnu services dns)} module provides services related to the
+@dfn{domain name system} (DNS).  It provides a server service for hosting an
+@emph{authoritative} DNS server for multiple zones, slave or master.  This
+service uses @uref{https://www.knot-dns.cz/, Knot DNS}.  And also a caching
+and forwarding DNS server for the LAN, which uses
+@uref{http://www.thekelleys.org.uk/dnsmasq/doc.html, dnsmasq}.

+@end lisp
+
+@deffn {Scheme Variable} knot-service-type
+This is the type for the Knot DNS server.
+
+Knot DNS is an authoritative DNS server, meaning that it can serve multiple
+zones, that is to say domain names you would buy from a registrar.  This
+server is not a resolver, meaning that it can only resolve names for which
+it is authoritative.  This server can be configured to serve zones as a
+master server or a slave server as a per-zone basis.  Slave zones will get
+their data from masters, and will serve it as an authoritative server.  From
+the point of view of a resolver, there is no difference between master and
+slave.
+
+The following data types are used to configure the Knot DNS server:
+@end deffn
+
+@deftp {Data Type} knot-key-configuration
+Data type representing a key.  This type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for other configuration fields to refer to this key. IDs must
+be unique and must not be empty.
+
+@item @code{algorithm} (default: @code{#f})
+The algorithm to use.  Choose between @code{#f}, @code{'hmac-md5},
+@code{'hmac-sha1}, @code{'hmac-sha224}, @code{'hmac-sha256},
+@code{'hmac-sha384} and @code{'hmac-sha512}.
+
+@item @code{secret} (default: @code{""})
+The secret key itself.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-acl-configuration
+Data type representing an Access Control List (ACL) configuration.  This
+type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for ether configuration fields to refer to this key. IDs must
+be unique and must not be empty.
+
+@item @code{address} (default: @code{'()})
+An ordered list of IP addresses, network subnets, or network ranges
+represented with strings.  The query must match one of them.  Empty value
+means that address match is not required.
+
+@item @code{key} (default: @code{'()})
+An ordered list of references to keys represented with strings.  The string
+must match a key ID defined in a @code{knot-key-configuration}.  No key
+means that a key is not require to match that ACL.
+
+@item @code{action} (default: @code{'()})
+An ordered list of actions that are permitted or forbidden by this ACL.
+Possible values are lists of zero or more elements from @code{'transfer},
+@code{'notify} and @code{'update}.
+
+@item @code{deny?} (default: @code{#f})
+When true, the ACL defines restrictions.  Listed actions are forbidden.
+When false, listed actions are allowed.
+
+@end table
+@end deftp
+
+@deftp {Data Type} zone-entry
+Data type represnting a record entry in a zone file.  This type has the
+following parameters:
+
+@table @asis
+@item @code{name} (default: @code{"@@"})
+The name of the record.  @code{"@@"} refers to the origin of the zone.
+Names are relative to the origin of the zone.  For example, in the
+@code{example.org} zone, @code{"ns.example.org"} actually refers to
+@code{ns.example.org.example.org}.  Names ending with a dot are absolute,
+which means that @code{"ns.example.org."} refers to @code{ns.example.org}.
+
+@item @code{ttl} (default: @code{""})
+The Time-To-Live (TTL) of this record.  If not set, the default TTL is used.
+
+@item @code{class} (default: @code{"IN"})
+The class of the record.  Knot currently supports only @code{"IN"} and
+partially @code{"CH"}.
+
+@item @code{type} (default: @code{"A"})
+The type of the record.  Common types include A (IPv4 address), AAAA (IPv6
+address), NS (Name Server) and MX (Mail eXchange).  Many other types are
+defined.
+
+@item @code{data} (default: @code{""})
+The data contained in the record.  For instance an IP address associated
+with an A record, or a domain name associated with an NS record.  Remember
+that domain names are relative to the origin unless they end with a dot.
+
+@end table
+@end deftp
+
+@deftp {Data Type} zone-file
+Data type representing the content of a zone file.  This type has the
+following parameters:
+
+@table @asis
+@item @code{entries} (default: @code{'()})
+The list of entries.  The SOA record is taken care of, so you don't need to
+put it in the list of entries.  This list should probably contain an entry
+for your primary authoritative DNS server.  Other than using a list of
+entries directly, you can use @code{define-zone-entries} to define a object
+containing the list of entries more easily, that you can later pass to the
+@code{entries} field of the @code{zone-file}.
+
+@item @code{origin} (default: @code{""})
+The name of your zone.  This parameter cannot be empty.
+
+@item @code{ns} (default: @code{"ns"})
+The domain of your primary authoritative DNS server.  The name is relative
+to the origin, unless it ends with a dot.  It is mandatory that this primary
+DNS server corresponds to an NS record in the zone and that it is associated
+to an IP address in the list of entries.
+
+@item @code{mail} (default: @code{"hostmaster"})
+An email address people can contact you at, as the owner of the zone.  This
+is translated as @code{<mail>@@<origin>}.
+
+@item @code{serial} (default: @code{1})
+The serial number of the zone.  As this is used to keep track of changes by
+both slaves and resolvers, it is mandatory that it @emph{never} decreases.
+Always increment it when you make a change in your zone.
+
+@item @code{refresh} (default: @code{(* 2 24 3600)})
+The frequency at which slaves will do a zone transfer.  This value is a
+number of seconds.  It can be computed by multiplications or with
+@code{(string->duration)}.
+
+@item @code{retry} (default: @code{(* 15 60)})
+The period after which a slave will retry to contact its master when it
+fails to do so a first time.
+
+@item @code{expiry} (default: @code{(* 14 24 3600)})
+Default TTL of records.  Existing records are considered correct for at most
+this amount of time.  After this period, resolvers will invalidate their
+cache and check again that it still exists.
+
+@item @code{nx} (default: @code{3600})
+Default TTL of inexistant records.  This delay is usually short because you
+want your new domains to reach everyone quickly.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-remote-configuration
+Data type representing a remote configuration.  This type has the following
+parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for other configuration fields to refer to this remote. IDs
+must be unique and must not be empty.
+
+@item @code{address} (default: @code{'()})
+An ordered list of destination IP addresses.  Addresses are tried in
+sequence.  An optional port can be given with the @@ separator.  For
+instance: @code{(list "1.2.3.4" "2.3.4.5@@53")}.  Default port is 53.
+
+@item @code{via} (default: @code{'()})
+An ordered list of source IP addresses.  An empty list will have Knot choose
+an appropriate source IP.  An optional port can be given with the @@
+separator.  The default is to choose at random.
+
+@item @code{key} (default: @code{#f})
+A reference to a key, that is a string containing the identifier of a key
+defined in a @code{knot-key-configuration} field.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-keystore-configuration
+Data type representing a keystore to hold dnssec keys.  This type has the
+following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+The id of the keystore.  It must not be empty.
+
+@item @code{backend} (default: @code{'pem})
+The backend to store the keys in.  Can be @code{'pem} or @code{'pkcs11}.
+
+@item @code{config} (default: @code{"/var/lib/knot/keys/keys"})
+The configuration string of the backend.  An example for the PKCS#11 is:
+@code{"pkcs11:token=knot;pin-value=1234
+/gnu/store/.../lib/pkcs11/libsofthsm2.so"}.  For the pem backend, the string
+reprensents a path in the file system.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-policy-configuration
+Data type representing a dnssec policy.  Knot DNS is able to automatically
+sign your zones.  It can either generate and manage your keys automatically
+or use keys that you generate.
+
+Dnssec is usually implemented using two keys: a Key Signing Key (KSK) that
+is used to sign the second, and a Zone Signing Key (ZSK) that is used to
+sign the zone.  In order to be trusted, the KSK needs to be present in the
+parent zone (usually a top-level domain).  If your registrar supports
+dnssec, you will have to send them your KSK's hash so they can add a DS
+record in their zone.  This is not automated and need to be done each time
+you change your KSK.
+
+The policy also defines the lifetime of keys.  Usually, ZSK can be changed
+easily and use weaker cryptographic functions (they use lower parameters) in
+order to sign records quickly, so they are changed often.  The KSK however
+requires manual interaction with the registrar, so they are changed less
+often and use stronger parameters because they sign only one record.
+
+This type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+The id of the policy.  It must not be empty.
+
+@item @code{keystore} (default: @code{"default"})
+A reference to a keystore, that is a string containing the identifier of a
+keystore defined in a @code{knot-keystore-configuration} field.  The
+@code{"default"} identifier means the default keystore (a kasp database that
+was setup by this service).
+
+@item @code{manual?} (default: @code{#f})
+Whether the key management is manual or automatic.
+
+@item @code{single-type-signing?} (default: @code{#f})
+When @code{#t}, use the Single-Type Signing Scheme.
+
+@item @code{algorithm} (default: @code{"ecdsap256sha256"})
+An algorithm of signing keys and issued signatures.
+
+@item @code{ksk-size} (default: @code{256})
+The length of the KSK.  Note that this value is correct for the default
+algorithm, but would be unsecure for other algorithms.
+
+@item @code{zsk-size} (default: @code{256})
+The length of the ZSK.  Note that this value is correct for the default
+algorithm, but would be unsecure for other algorithms.
+
+@item @code{dnskey-ttl} (default: @code{'default})
+The TTL value for DNSKEY records added into zone apex.  The special
+@code{'default} value means same as the zone SOA TTL.
+
+@item @code{zsk-lifetime} (default: @code{(* 30 24 3600)})
+The period between ZSK publication and the next rollover initiation.
+
+@item @code{propagation-delay} (default: @code{(* 24 3600)})
+An extra delay added for each key rollover step.  This value should be high
+enough to cover propagation of data from the master server to all slaves.
+
+@item @code{rrsig-lifetime} (default: @code{(* 14 24 3600)})
+A validity period of newly issued signatures.
+
+@item @code{rrsig-refresh} (default: @code{(* 7 24 3600)})
+A period how long before a signature expiration the signature will be
+refreshed.
+
+@item @code{nsec3?} (default: @code{#f})
+When @code{#t}, NSEC3 will be used instead of NSEC.
+
+@item @code{nsec3-iterations} (default: @code{5})
+The number of additional times the hashing is performed.
+
+@item @code{nsec3-salt-length} (default: @code{8})
+The length of a salt field in octets, which is appended to the original
+owner name before hashing.
+
+@item @code{nsec3-salt-lifetime} (default: @code{(* 30 24 3600)})
+The validity period of newly issued salt field.

+
+@deftp {Data Type} knot-zone-configuration
+Data type representing a zone served by Knot.  This type has the following
+parameters:

+The domain served by this configuration.  It must not be empty.
+
+@item @code{file} (default: @code{""})

+zones.  Empty means default location that depends on the domain name.
+
+@item @code{zone} (default: @code{(zone-file)})
+The content of the zone file.  This parameter is ignored by slave zones.  It
+must contain a zone-file record.

+@node Power Management Services
+@subsubsection Power Management Services
+
+@cindex tlp
+@cindex power management with TLP
+@subsubheading TLP daemon
+
+The @code{(gnu services pm)} module provides a Guix service definition for
+the Linux power management tool TLP.
+
+TLP enables various powersaving modes in userspace and kernel.  Contrary to
+@code{upower-service}, it is not a passive, monitoring tool, as it will
+apply custom settings each time a new power source is detected.  More
+information can be found at @uref{http://linrunner.de/en/tlp/tlp.html, TLP
+home page}.
+
+@deffn {Scheme Variable} tlp-service-type
+The service type for the TLP tool.  Its value should be a valid TLP
+configuration (see below).  To use the default settings, simply write:
+@example
+(service tlp-service-type)
+@end example
+@end deffn
+
+By default TLP does not need much configuration but most TLP parameters can
+be tweaked using @code{tlp-configuration}.
+
+Each parameter definition is preceded by its type; for example,
+@samp{boolean foo} indicates that the @code{foo} parameter should be
+specified as a boolean.  Types starting with @code{maybe-} denote parameters
+that won't show up in TLP config file when their value is @code{'disabled}.
+
+@c The following documentation was initially generated by
+@c (generate-tlp-documentation) in (gnu services pm).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as TLP updates.

+@subsubheading Transparent Emulation with QEMU
+
+@cindex emulation
+@cindex @code{binfmt_misc}
+@code{qemu-binfmt-service-type} provides support for transparent emulation
+of program binaries built for different architectures---e.g., it allows you
+to transparently execute an ARMv7 program on an x86_64 machine.  It achieves
+this by combining the @uref{https://www.qemu.org, QEMU} emulator and the
+@code{binfmt_misc} feature of the kernel Linux.
+
+@defvr {Scheme Variable} qemu-binfmt-service-type
+This is the type of the QEMU/binfmt service for transparent emulation.  Its
+value must be a @code{qemu-binfmt-configuration} object, which specifies the
+QEMU package to use as well as the architecture we want to emulated:
+
+@example
+(service qemu-binfmt-service-type
+         (qemu-binfmt-configuration
+           (platforms (lookup-qemu-platforms "arm" "aarch64" "ppc"))))
+@end example
+
+In this example, we enable transparent emulation for the ARM and aarch64
+platforms.  Running @code{herd stop qemu-binfmt} turns it off, and running
+@code{herd start qemu-binfmt} turns it back on (@pxref{Invoking herd, the
+@command{herd} command,, shepherd, The GNU Shepherd Manual}).
+@end defvr
+
+@deftp {Data Type} qemu-binfmt-configuration
+This is the configuration for the @code{qemu-binfmt} service.
+
+@table @asis
+@item @code{platforms} (default: @code{'()})
+The list of emulated QEMU platforms.  Each item must be a @dfn{platform
+object} as returned by @code{lookup-qemu-platforms} (see below).
+
+@item @code{guix-support?} (default: @code{#f})
+When it is true, QEMU and all its dependencies are added to the build
+environment of @command{guix-daemon} (@pxref{Aufruf des guix-daemon,
+@code{--chroot-directory} option}).  This allows the @code{binfmt_misc}
+handlers to be used within the build environment, which in turn means that
+you can transparently build programs for another architecture.
+
+For example, let's suppose you're on an x86_64 machine and you have this
+service:
+
+@example
+(service qemu-binfmt-service-type
+         (qemu-binfmt-configuration
+           (platforms (lookup-qemu-platforms "arm"))
+           (guix-support? #t)))
+@end example
+
+You can run:
+
+@example
+guix build -s armhf-linux inkscape
+@end example
+
+@noindent
+and it will build Inkscape for ARMv7 @emph{as if it were a native build},
+transparently using QEMU to emulate the ARMv7 CPU.  Pretty handy if you'd
+like to test a package build for an architecture you don't have access to!
+
+@item @code{qemu} (default: @code{qemu})
+The QEMU package to use.
+@end table
+@end deftp
+
+@deffn {Scheme Procedure} lookup-qemu-platforms @var{platforms}@dots{}

+@cindex Gitolite service
+@cindex Git, hosting
+@uref{http://gitolite.com/gitolite/, Gitolite} is a tool for hosting Git
+repositories on a central server.
+
+Gitolite can handle multiple repositories and users, and supports flexible
+configuration of the permissions for the users on the repositories.
+
+The following example will configure Gitolite using the default @code{git}
+user, and the provided SSH public key.
+
+@example
+(service gitolite-service-type
+         (gitolite-configuration
+           (admin-pubkey (plain-file

+                           "ssh-rsa AAAA... guix@@example.com"))))
+@end example
+
+Gitolite is configured through a special admin repository which you can
+clone, for example, if you setup Gitolite on @code{example.com}, you would
+run the following command to clone the admin repository.
+
+@example
+git clone git@@example.com:gitolite-admin
+@end example
+
+When the Gitolite service is activated, the provided @code{admin-pubkey}
+will be inserted in to the @file{keydir} directory in the gitolite-admin
+repository.  If this results in a change in the repository, it will be
+committed using the message ``gitolite setup by GNU Guix''.

+
+@cindex setuid programs
+Some programs need to run with ``root'' privileges, even when they are
+launched by unprivileged users.  A notorious example is the @command{passwd}
+program, which users can run to change their password, and which needs to
+access the @file{/etc/passwd} and @file{/etc/shadow} files---something
+normally restricted to root, for obvious security reasons.  To address that,
+these executables are @dfn{setuid-root}, meaning that they always run with
+root privileges (@pxref{How Change Persona,,, libc, The GNU C Library
+Reference Manual}, for more info about the setuid mechanism.)
+
+The store itself @emph{cannot} contain setuid programs: that would be a
+security issue since any user on the system can write derivations that
+populate the store (@pxref{Der Store}).  Thus, a different mechanism is
+used: instead of changing the setuid bit directly on files that are in the
+store, we let the system administrator @emph{declare} which programs should
+be setuid root.
+
+The @code{setuid-programs} field of an @code{operating-system} declaration
+contains a list of G-expressions denoting the names of programs to be
+setuid-root (@pxref{Das Konfigurationssystem nutzen}).  For instance, the
+@command{passwd} program, which is part of the Shadow package, can be
+designated by this G-expression (@pxref{G-Ausdrücke}):
+
+@example
+#~(string-append #$shadow "/bin/passwd")

+A default set of setuid programs is defined by the @code{%setuid-programs}

+Under the hood, the actual setuid programs are created in the

+@node X.509-Zertifikate
+@subsection X.509-Zertifikate
+
+@cindex HTTPS, certificates
+@cindex X.509 certificates
+@cindex TLS
+Web servers available over HTTPS (that is, HTTP over the transport-layer
+security mechanism, TLS) send client programs an @dfn{X.509 certificate}
+that the client can then use to @emph{authenticate} the server.  To do that,
+clients verify that the server's certificate is signed by a so-called
+@dfn{certificate authority} (CA).  But to verify the CA's signature, clients
+must have first acquired the CA's certificate.
+
+Web browsers such as GNU@tie{}IceCat include their own set of CA
+certificates, such that they are able to verify CA signatures
+out-of-the-box.
+
+However, most other programs that can talk HTTPS---@command{wget},
+@command{git}, @command{w3m}, etc.---need to be told where CA certificates
+can be found.
+
+@cindex @code{nss-certs}
+In GuixSD, this is done by adding a package that provides certificates to
+the @code{packages} field of the @code{operating-system} declaration
+(@pxref{„operating-system“-Referenz}).  GuixSD includes one such package,
+@code{nss-certs}, which is a set of CA certificates provided as part of
+Mozilla's Network Security Services.
+
+Note that it is @emph{not} part of @var{%base-packages}, so you need to
+explicitly add it.  The @file{/etc/ssl/certs} directory, which is where most
+applications and libraries look for certificates by default, points to the
+certificates installed globally.
+
+Unprivileged users, including users of Guix on a foreign distro, can also
+install their own certificate package in their profile.  A number of
+environment variables need to be defined so that applications and libraries
+know where to find them.  Namely, the OpenSSL library honors the
+@code{SSL_CERT_DIR} and @code{SSL_CERT_FILE} variables.  Some applications
+add their own environment variables; for instance, the Git version control
+system honors the certificate bundle pointed to by the @code{GIT_SSL_CAINFO}
+environment variable.  Thus, you would typically run something like:
+
+@example
+$ guix package -i nss-certs
+$ export SSL_CERT_DIR="$HOME/.guix-profile/etc/ssl/certs"
+$ export SSL_CERT_FILE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
+$ export GIT_SSL_CAINFO="$SSL_CERT_FILE"
+@end example
+
+As another example, R requires the @code{CURL_CA_BUNDLE} environment
+variable to point to a certificate bundle, so you would have to run
+something like this:
+
+@example
+$ guix package -i nss-certs
+$ export CURL_CA_BUNDLE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
+@end example
+
+For other applications you may want to look up the required environment
+variable in the relevant documentation.

+@node Name Service Switch
+@subsection Name Service Switch
+
+@cindex name service switch
+@cindex NSS
+The @code{(gnu system nss)} module provides bindings to the configuration
+file of the libc @dfn{name service switch} or @dfn{NSS} (@pxref{NSS
+Configuration File,,, libc, The GNU C Library Reference Manual}).  In a
+nutshell, the NSS is a mechanism that allows libc to be extended with new
+``name'' lookup methods for system databases, which includes host names,
+service names, user accounts, and more (@pxref{Name Service Switch, System
+Databases and Name Service Switch,, libc, The GNU C Library Reference
+Manual}).
+
+The NSS configuration specifies, for each system database, which lookup
+method is to be used, and how the various methods are chained together---for
+instance, under which circumstances NSS should try the next method in the
+list.  The NSS configuration is given in the @code{name-service-switch}
+field of @code{operating-system} declarations (@pxref{„operating-system“-Referenz, @code{name-service-switch}}).
+
+@cindex nss-mdns
+@cindex .local, host name lookup
+As an example, the declaration below configures the NSS to use the
+@uref{http://0pointer.de/lennart/projects/nss-mdns/, @code{nss-mdns}
+back-end}, which supports host name lookups over multicast DNS (mDNS)  for
+host names ending in @code{.local}:
+
+@example
+(name-service-switch
+   (hosts (list %files    ;first, check /etc/hosts
+
+                ;; If the above did not succeed, try
+                ;; with 'mdns_minimal'.
+                (name-service
+                  (name "mdns_minimal")
+
+                  ;; 'mdns_minimal' is authoritative for
+                  ;; '.local'.  When it returns "not found",
+                  ;; no need to try the next methods.
+                  (reaction (lookup-specification
+                             (not-found => return))))
+
+                ;; Then fall back to DNS.
+                (name-service
+                  (name "dns"))
+
+                ;; Finally, try with the "full" 'mdns'.
+                (name-service
+                  (name "mdns")))))
+@end example
+
+Do not worry: the @code{%mdns-host-lookup-nss} variable (see below)
+contains this configuration, so you will not have to type it if all you want
+is to have @code{.local} host lookup working.
+
+Note that, in this case, in addition to setting the
+@code{name-service-switch} of the @code{operating-system} declaration, you
+also need to use @code{avahi-service} (@pxref{Netzwerkdienste,
+@code{avahi-service}}), or @var{%desktop-services}, which includes it
+(@pxref{Desktop-Dienste}).  Doing this makes @code{nss-mdns} accessible to
+the name service cache daemon (@pxref{Basisdienste, @code{nscd-service}}).
+
+For convenience, the following variables provide typical NSS configurations.
+
+@defvr {Scheme Variable} %default-nss
+This is the default name service switch configuration, a
+@code{name-service-switch} object.
+@end defvr
+
+@defvr {Scheme Variable} %mdns-host-lookup-nss
+This is the name service switch configuration with support for host name
+lookup over multicast DNS (mDNS) for host names ending in @code{.local}.

+direct mapping of the configuration file format of the C library , so please
+refer to the C library manual for more information (@pxref{NSS Configuration
+File,,, libc, The GNU C Library Reference Manual}).  Compared to the
+configuration file format of libc NSS, it has the advantage not only of
+adding this warm parenthetic feel that we like, but also static checks: you
+will know about syntax errors and typos as soon as you run @command{guix
+system}.
+
+@deftp {Data Type} name-service-switch

+@node Initiale RAM-Disk
+@subsection Initiale RAM-Disk
+
+@cindex initrd
+@cindex initial RAM disk
+For bootstrapping purposes, the Linux-Libre kernel is passed an @dfn{initial
+RAM disk}, or @dfn{initrd}.  An initrd contains a temporary root file system
+as well as an initialization script.  The latter is responsible for mounting
+the real root file system, and for loading any kernel modules that may be
+needed to achieve that.
+
+The @code{initrd-modules} field of an @code{operating-system} declaration
+allows you to specify Linux-libre kernel modules that must be available in
+the initrd.  In particular, this is where you would list modules needed to
+actually drive the hard disk where your root partition is---although the
+default value of @code{initrd-modules} should cover most use cases.  For
+example, assuming you need the @code{megaraid_sas} module in addition to the
+default modules to be able to access your root file system, you would write:
+
+@example
+(operating-system
+  ;; @dots{}
+  (initrd-modules (cons "megaraid_sas" %base-initrd-modules)))
+@end example
+
+@defvr {Scheme Variable} %base-initrd-modules
+This is the list of kernel modules included in the initrd by default.
+@end defvr
+
+Furthermore, if you need lower-level customization, the @code{initrd} field
+of an @code{operating-system} declaration allows you to specify which initrd
+you would like to use.  The @code{(gnu system linux-initrd)} module provides
+three ways to build an initrd: the high-level @code{base-initrd} procedure
+and the low-level @code{raw-initrd} and @code{expression->initrd}
+procedures.
+
+The @code{base-initrd} procedure is intended to cover most common uses.  For
+example, if you want to add a bunch of kernel modules to be loaded at boot
+time, you can define the @code{initrd} field of the operating system
+declaration like this:
+
+@example
+(initrd (lambda (file-systems . rest)
+          ;; Create a standard initrd but set up networking
+          ;; with the parameters QEMU expects by default.
+          (apply base-initrd file-systems
+                 #:qemu-networking? #t
+                 rest)))
+@end example
+
+The @code{base-initrd} procedure also handles common use cases that involves
+using the system as a QEMU guest, or as a ``live'' system with volatile root
+file system.
+
+The @code{base-initrd} procedure is built from @code{raw-initrd} procedure.
+Unlike @code{base-initrd}, @code{raw-initrd} doesn't do anything high-level,
+such as trying to guess which kernel modules and packages should be included
+to the initrd. An example use of @code{raw-initrd} is when a user has a
+custom Linux kernel configuration and default kernel modules included by
+@code{base-initrd} are not available.
+
+The initial RAM disk produced by @code{base-initrd} or @code{raw-initrd}
+honors several options passed on the Linux kernel command line (that is,
+arguments passed @i{via} the @code{linux} command of GRUB, or the
+@code{-append} option of QEMU), notably:
+
+@table @code
+@item --load=@var{boot}
+Tell the initial RAM disk to load @var{boot}, a file containing a Scheme
+program, once it has mounted the root file system.
+
+GuixSD uses this option to yield control to a boot program that runs the
+service activation programs and then spawns the GNU@tie{}Shepherd, the
+initialization system.
+
+@item --root=@var{root}
+Mount @var{root} as the root file system.  @var{root} can be a device name
+like @code{/dev/sda1}, a file system label, or a file system UUID.
+
+@item --system=@var{System}
+Have @file{/run/booted-system} and @file{/run/current-system} point to
+@var{system}.
+
+@item modprobe.blacklist=@var{modules}@dots{}
+@cindex module, black-listing
+@cindex black list, of kernel modules
+Instruct the initial RAM disk as well as the @command{modprobe} command
+(from the kmod package) to refuse to load @var{modules}.  @var{modules} must
+be a comma-separated list of module names---e.g., @code{usbkbd,9pnet}.
+
+@item --repl
+Start a read-eval-print loop (REPL) from the initial RAM disk before it
+tries to load kernel modules and to mount the root file system.  Our
+marketing team calls it @dfn{boot-to-Guile}.  The Schemer in you will love
+it.  @xref{Using Guile Interactively,,, guile, GNU Guile Reference Manual},
+for more information on Guile's REPL.

+@subsection Bootloader-Konfiguration
+
+@cindex bootloader
+@cindex boot loader
+
+The operating system supports multiple bootloaders.  The bootloader is
+configured using @code{bootloader-configuration} declaration.  All the
+fields of this structure are bootloader agnostic except for one field,
+@code{bootloader} that indicates the bootloader to be configured and
+installed.
+
+Some of the bootloaders do not honor every field of
+@code{bootloader-configuration}.  For instance, the extlinux bootloader does
+not support themes and thus ignores the @code{theme} field.
+
+@deftp {Data Type} bootloader-configuration
+The type of a bootloader configuration declaration.
+
+@table @asis
+
+@item @code{bootloader}
+@cindex EFI, bootloader
+@cindex UEFI, bootloader
+@cindex BIOS, bootloader
+The bootloader to use, as a @code{bootloader} object. For now
+@code{grub-bootloader}, @code{grub-efi-bootloader},
+@code{extlinux-bootloader} and @code{u-boot-bootloader} are supported.
+
+@vindex grub-efi-bootloader
+@code{grub-efi-bootloader} allows to boot on modern systems using the
+@dfn{Unified Extensible Firmware Interface} (UEFI).  This is what you should
+use if the installation image contains a @file{/sys/firmware/efi} directory
+when you boot it on your system.
+
+@vindex grub-bootloader
+@code{grub-bootloader} allows you to boot in particular Intel-based machines
+in ``legacy'' BIOS mode.
+
+@cindex ARM, bootloaders
+@cindex AArch64, bootloaders
+Available bootloaders are described in @code{(gnu bootloader @dots{})}
+modules.  In particular, @code{(gnu bootloader u-boot)} contains definitions
+of bootloaders for a wide range of ARM and AArch64 systems, using the
+@uref{http://www.denx.de/wiki/U-Boot/, U-Boot bootloader}.
+
+@item @code{target}
+This is a string denoting the target onto which to install the bootloader.
+
+The interpretation depends on the bootloader in question.  For
+@code{grub-bootloader}, for example, it should be a device name understood
+by the bootloader @command{installer} command, such as @code{/dev/sda} or
+@code{(hd0)} (@pxref{Invoking grub-install,,, grub, GNU GRUB Manual}).  For
+@code{grub-efi-bootloader}, it should be the mount point of the EFI file
+system, usually @file{/boot/efi}.
+
+@item @code{menu-entries} (default: @code{()})
+A possibly empty list of @code{menu-entry} objects (see below), denoting
+entries to appear in the bootloader menu, in addition to the current system
+entry and the entry pointing to previous system generations.
+
+@item @code{default-entry} (default: @code{0})
+The index of the default boot menu entry.  Index 0 is for the entry of the
+current system.
+
+@item @code{timeout} (default: @code{5})
+The number of seconds to wait for keyboard input before booting.  Set to 0
+to boot immediately, and to -1 to wait indefinitely.
+
+@item @code{theme} (default: @var{#f})
+The bootloader theme object describing the theme to use.  If no theme is
+provided, some bootloaders might use a default theme, that's true for GRUB.
+
+@item @code{terminal-outputs} (default: @code{'gfxterm})
+The output terminals used for the bootloader boot menu, as a list of
+symbols.  GRUB accepts the values: @code{console}, @code{serial},
+@code{serial_@{0-3@}}, @code{gfxterm}, @code{vga_text}, @code{mda_text},
+@code{morse}, and @code{pkmodem}.  This field corresponds to the GRUB
+variable @code{GRUB_TERMINAL_OUTPUT} (@pxref{Simple configuration,,,
+grub,GNU GRUB manual}).
+
+@item @code{terminal-inputs} (default: @code{'()})
+The input terminals used for the bootloader boot menu, as a list of
+symbols.  For GRUB, the default is the native platform terminal as
+determined at run-time.  GRUB accepts the values: @code{console},
+@code{serial}, @code{serial_@{0-3@}}, @code{at_keyboard}, and
+@code{usb_keyboard}.  This field corresponds to the GRUB variable
+@code{GRUB_TERMINAL_INPUT} (@pxref{Simple configuration,,, grub,GNU GRUB
+manual}).
+
+@item @code{serial-unit} (default: @code{#f})
+The serial unit used by the bootloader, as an integer from 0 to 3.  For
+GRUB, it is chosen at run-time; currently GRUB chooses 0, which corresponds
+to COM1 (@pxref{Serial terminal,,, grub,GNU GRUB manual}).
+
+@item @code{serial-speed} (default: @code{#f})
+The speed of the serial interface, as an integer.  For GRUB, the default
+value is chosen at run-time; currently GRUB chooses 9600@tie{}bps
+(@pxref{Serial terminal,,, grub,GNU GRUB manual}).

+@cindex boot menu
+Should you want to list additional boot menu entries @i{via} the
+@code{menu-entries} field above, you will need to create them with the
+@code{menu-entry} form.  For example, imagine you want to be able to boot
+another distro (hard to imagine!), you can define a menu entry along these
+lines:
+
+@example
+(menu-entry
+  (label "The Other Distro")
+  (linux "/boot/old/vmlinux-2.6.32")
+  (linux-arguments '("root=/dev/sda2"))
+  (initrd "/boot/old/initrd"))

+
+Details below.
+
+@deftp {Data Type} menu-entry
+The type of an entry in the bootloader menu.
+
+@table @asis
+
+@item @code{label}
+The label to show in the menu---e.g., @code{"GNU"}.
+
+@item @code{linux}
+The Linux kernel image to boot, for example:
+
+@example
+(file-append linux-libre "/bzImage")
+@end example
+
+For GRUB, it is also possible to specify a device explicitly in the file
+path using GRUB's device naming convention (@pxref{Naming convention,,,
+grub, GNU GRUB manual}), for example:
+
+@example
+"(hd0,msdos1)/boot/vmlinuz"
+@end example
+
+If the device is specified explicitly as above, then the @code{device} field
+is ignored entirely.
+
+@item @code{linux-arguments} (default: @code{()})
+The list of extra Linux kernel command-line arguments---e.g.,
+@code{("console=ttyS0")}.
+
+@item @code{initrd}
+A G-Expression or string denoting the file name of the initial RAM disk to
+use (@pxref{G-Ausdrücke}).
+@item @code{device} (default: @code{#f})
+The device where the kernel and initrd are to be found---i.e., for GRUB,
+@dfn{root} for this menu entry (@pxref{root,,, grub, GNU GRUB manual}).
+
+This may be a file system label (a string), a file system UUID (a
+bytevector, @pxref{Dateisysteme}), or @code{#f}, in which case the
+bootloader will search the device containing the file specified by the
+@code{linux} field (@pxref{search,,, grub, GNU GRUB manual}).  It must

+@node Aufruf von guix system
+@subsection Invoking @code{guix system}
+
+Once you have written an operating system declaration as seen in the
+previous section, it can be @dfn{instantiated} using the @command{guix
+system} command.  The synopsis is:
+
+@example
+guix system @var{options}@dots{} @var{action} @var{file}
+@end example
+
+@var{file} must be the name of a file containing an @code{operating-system}
+declaration.  @var{action} specifies how the operating system is
+instantiated.  Currently the following values are supported:
+
+@table @code
+@item search
+Display available service type definitions that match the given regular
+expressions, sorted by relevance:
+
+@example
+$ guix system search console font
+name: console-fonts
+location: gnu/services/base.scm:729:2
+extends: shepherd-root
+description: Install the given fonts on the specified ttys (fonts are
++ per virtual console on GNU/Linux).  The value of this service is a list
++ of tty/font pairs like:
++ 
++      '(("tty1" . "LatGrkCyr-8x16"))
+relevance: 20
+
+name: mingetty

+description: Provide console login using the `mingetty' program.
+relevance: 2
+
+name: login
+location: gnu/services/base.scm:775:2
+extends: pam
+description: Provide a console log-in service as specified by its
++ configuration value, a `login-configuration' object.
+relevance: 2
+
+@dots{}
+@end example
+
+As for @command{guix package --search}, the result is written in
+@code{recutils} format, which makes it easy to filter the output
+(@pxref{Top, GNU recutils databases,, recutils, GNU recutils manual}).
+
+@item reconfigure
+Build the operating system described in @var{file}, activate it, and switch
+to it@footnote{This action (and the related actions @code{switch-generation}
+and @code{roll-back}) are usable only on systems already running GuixSD.}.
+
+This effects all the configuration specified in @var{file}: user accounts,
+system services, global package list, setuid programs, etc.  The command
+starts system services specified in @var{file} that are not currently
+running; if a service is currently running this command will arrange for it
+to be upgraded the next time it is stopped (e.g.@: by @code{herd stop X} or
+@code{herd restart X}).
+
+This command creates a new generation whose number is one greater than the
+current generation (as reported by @command{guix system list-generations}).
+If that generation already exists, it will be overwritten.  This behavior
+mirrors that of @command{guix package} (@pxref{Aufruf von guix package}).
+
+It also adds a bootloader menu entry for the new OS configuration, ---unless
+@option{--no-bootloader} is passed.  For GRUB, it moves entries for older
+configurations to a submenu, allowing you to choose an older system
+generation at boot time should you need it.
+
+@quotation Anmerkung
+@c The paragraph below refers to the problem discussed at
+@c <http://lists.gnu.org/archive/html/guix-devel/2014-08/msg00057.html>.
+It is highly recommended to run @command{guix pull} once before you run
+@command{guix system reconfigure} for the first time (@pxref{Aufruf von guix pull}).  Failing to do that you would see an older version of Guix once
+@command{reconfigure} has completed.
+@end quotation
+
+@item switch-generation
+@cindex Generationen
+Switch to an existing system generation.  This action atomically switches
+the system profile to the specified system generation.  It also rearranges
+the system's existing bootloader menu entries.  It makes the menu entry for
+the specified system generation the default, and it moves the entries for
+the other generatiors to a submenu, if supported by the bootloader being
+used.  The next time the system boots, it will use the specified system
+generation.
+
+The bootloader itself is not being reinstalled when using this command.
+Thus, the installed bootloader is used with an updated configuration file.
+
+The target generation can be specified explicitly by its generation number.
+For example, the following invocation would switch to system generation 7:
+
+@example
+guix system switch-generation 7
+@end example
+
+The target generation can also be specified relative to the current
+generation with the form @code{+N} or @code{-N}, where @code{+3} means ``3
+generations ahead of the current generation,'' and @code{-1} means ``1
+generation prior to the current generation.'' When specifying a negative
+value such as @code{-1}, you must precede it with @code{--} to prevent it
+from being parsed as an option.  For example:
+
+@example
+guix system switch-generation -- -1
+@end example
+
+Currently, the effect of invoking this action is @emph{only} to switch the
+system profile to an existing generation and rearrange the bootloader menu
+entries.  To actually start using the target system generation, you must
+reboot after running this action.  In the future, it will be updated to do
+the same things as @command{reconfigure}, like activating and deactivating
+services.
+
+This action will fail if the specified generation does not exist.
+
+@item roll-back
+@cindex rücksetzen
+Switch to the preceding system generation.  The next time the system boots,
+it will use the preceding system generation.  This is the inverse of
+@command{reconfigure}, and it is exactly the same as invoking
+@command{switch-generation} with an argument of @code{-1}.
+
+Currently, as with @command{switch-generation}, you must reboot after
+running this action to actually start using the preceding system generation.
+
+@item build
+Build the derivation of the operating system, which includes all the
+configuration files and programs needed to boot and run the system.  This
+action does not actually install anything.
+
+@item init
+Populate the given directory with all the files necessary to run the
+operating system specified in @var{file}.  This is useful for first-time
+installations of GuixSD.  For instance:
+
+@example
+guix system init my-os-config.scm /mnt
+@end example
+
+copies to @file{/mnt} all the store items required by the configuration
+specified in @file{my-os-config.scm}.  This includes configuration files,
+packages, and so on.  It also creates other essential files needed for the
+system to operate correctly---e.g., the @file{/etc}, @file{/var}, and
+@file{/run} directories, and the @file{/bin/sh} file.
+
+This command also installs bootloader on the target specified in
+@file{my-os-config}, unless the @option{--no-bootloader} option was passed.
+
+@item vm
+@cindex virtual machine
+@cindex VM
+@anchor{guix system vm}
+Build a virtual machine that contains the operating system declared in
+@var{file}, and return a script to run that virtual machine (VM).  Arguments
+given to the script are passed to QEMU as in the example below, which
+enables networking and requests 1@tie{}GiB of RAM for the emulated machine:
+
+@example
+$ /gnu/store/@dots{}-run-vm.sh -m 1024 -net user
+@end example
+
+The VM shares its store with the host system.
+
+Additional file systems can be shared between the host and the VM using the
+@code{--share} and @code{--expose} command-line options: the former
+specifies a directory to be shared with write access, while the latter
+provides read-only access to the shared directory.
+
+The example below creates a VM in which the user's home directory is
+accessible read-only, and where the @file{/exchange} directory is a
+read-write mapping of @file{$HOME/tmp} on the host:
+
+@example
+guix system vm my-config.scm \
+   --expose=$HOME --share=$HOME/tmp=/exchange
+@end example
+
+On GNU/Linux, the default is to boot directly to the kernel; this has the
+advantage of requiring only a very tiny root disk image since the store of
+the host can then be mounted.
+
+The @code{--full-boot} option forces a complete boot sequence, starting with
+the bootloader.  This requires more disk space since a root image containing
+at least the kernel, initrd, and bootloader data files must be created.  The
+@code{--image-size} option can be used to specify the size of the image.
+
+@cindex System images, creation in various formats
+@cindex Creating system images in various formats
+@item vm-image
+@itemx disk-image
+@itemx docker-image
+Return a virtual machine, disk image, or Docker image of the operating
+system declared in @var{file} that stands alone.  By default, @command{guix
+system} estimates the size of the image needed to store the system, but you
+can use the @option{--image-size} option to specify a value.  Docker images
+are built to contain exactly what they need, so the @option{--image-size}
+option is ignored in the case of @code{docker-image}.
+
+You can specify the root file system type by using the
+@option{--file-system-type} option.  It defaults to @code{ext4}.
+
+When using @code{vm-image}, the returned image is in qcow2 format, which the
+QEMU emulator can efficiently use. @xref{GuixSD in einer VM starten}, for more
+information on how to run the image in a virtual machine.
+
+When using @code{disk-image}, a raw disk image is produced; it can be copied
+as is to a USB stick, for instance.  Assuming @code{/dev/sdc} is the device
+corresponding to a USB stick, one can copy the image to it using the
+following command:
+
+@example
+# dd if=$(guix system disk-image my-os.scm) of=/dev/sdc
+@end example
+
+When using @code{docker-image}, a Docker image is produced.  Guix builds the
+image from scratch, not from a pre-existing Docker base image.  As a result,
+it contains @emph{exactly} what you define in the operating system
+configuration file.  You can then load the image and launch a Docker
+container using commands like the following:
+
+@example
+image_id="$(docker load < guixsd-docker-image.tar.gz)"
+docker run -e GUIX_NEW_SYSTEM=/var/guix/profiles/system \\
+    --entrypoint /var/guix/profiles/system/profile/bin/guile \\
+    $image_id /var/guix/profiles/system/boot
+@end example
+
+This command starts a new Docker container from the specified image.  It
+will boot the GuixSD system in the usual manner, which means it will start
+any services you have defined in the operating system configuration.
+Depending on what you run in the Docker container, it may be necessary to
+give the container additional permissions.  For example, if you intend to
+build software using Guix inside of the Docker container, you may need to
+pass the @option{--privileged} option to @code{docker run}.
+
+@item container
+Return a script to run the operating system declared in @var{file} within a
+container.  Containers are a set of lightweight isolation mechanisms
+provided by the kernel Linux-libre.  Containers are substantially less
+resource-demanding than full virtual machines since the kernel, shared
+objects, and other resources can be shared with the host system; this also
+means they provide thinner isolation.
+
+Currently, the script must be run as root in order to support more than a
+single user and group.  The container shares its store with the host system.
+
+As with the @code{vm} action (@pxref{guix system vm}), additional file
+systems to be shared between the host and container can be specified using
+the @option{--share} and @option{--expose} options:
+
+@example
+guix system container my-config.scm \
+   --expose=$HOME --share=$HOME/tmp=/exchange
+@end example
+
+@quotation Anmerkung
+This option requires Linux-libre 3.19 or newer.

+@item --expression=@var{expr}
+@itemx -e @var{expr}

+This is used to generate the GuixSD installer @pxref{Ein Abbild zur Installation erstellen}).
+
+@item --system=@var{System}
+@itemx -s @var{system}
+Attempt to build for @var{system} instead of the host system type.  This

+@itemx -d
+Return the derivation file name of the given operating system without

+@item --file-system-type=@var{type}
+@itemx -t @var{type}
+For the @code{disk-image} action, create a file system of the given

+When this option is omitted, @command{guix system} uses @code{ext4}.
+
+@cindex ISO-9660 format
+@cindex CD image format
+@cindex DVD image format
+@code{--file-system-type=iso9660} produces an ISO-9660 image, suitable for
+burning on CDs and DVDs.
+
+@item --image-size=@var{size}
+For the @code{vm-image} and @code{disk-image} actions, create an image of
+the given @var{size}.  @var{size} may be a number of bytes, or it may
+include a unit as a suffix (@pxref{Block size, size specifications,,
+coreutils, GNU Coreutils}).
+
+When this option is omitted, @command{guix system} computes an estimate of
+the image size as a function of the size of the system declared in

+
+@item --root=@var{file}
+@itemx -r @var{file}
+Make @var{file} a symlink to the result, and register it as a garbage

+
+@item --skip-checks
+Skip pre-installation safety checks.
+
+By default, @command{guix system init} and @command{guix system reconfigure}
+perform safety checks: they make sure the file systems that appear in the
+@code{operating-system} declaration actually exist (@pxref{Dateisysteme}),
+and that any Linux kernel modules that may be needed at boot time are listed
+in @code{initrd-modules} (@pxref{Initiale RAM-Disk}).  Passing this option
+skips these tests altogether.
+
+@item --on-error=@var{strategy}
+Apply @var{strategy} when an error occurs when reading @var{file}.
+@var{strategy} may be one of the following:
+
+@table @code
+@item nothing-special
+Report the error concisely and exit.  This is the default strategy.

+
+@item debug
+Report the error and enter Guile's debugger.  From there, you can run

+
+@table @code
+
+@item list-generations
+List a summary of each generation of the operating system available on disk,

+option of @command{guix package} (@pxref{Aufruf von guix package}).
+
+Optionally, one can specify a pattern, with the same syntax that is used in
+@command{guix package --list-generations}, to restrict the list of
+generations displayed.  For instance, the following command displays

+@subsection Running GuixSD in a Virtual Machine
+
+@cindex virtual machine
+To run GuixSD in a virtual machine (VM), one can either use the pre-built
+GuixSD VM image distributed at
+@indicateurl{https://alpha.gnu.org/gnu/guix/guixsd-vm-image-@value{VERSION}.@var{system}.xz}
+, or build their own virtual machine image using @command{guix system
+vm-image} (@pxref{Aufruf von guix system}).  The returned image is in qcow2
+format, which the @uref{http://qemu.org/, QEMU emulator} can efficiently
+use.
+
+@cindex QEMU
+If you built your own image, you must copy it out of the store (@pxref{Der Store}) and give yourself permission to write to the copy before you can use
+it.  When invoking QEMU, you must choose a system emulator that is suitable
+for your hardware platform.  Here is a minimal QEMU invocation that will
+boot the result of @command{guix system vm-image} on x86_64 hardware:
+
+@example
+$ qemu-system-x86_64 \
+   -net user -net nic,model=virtio \
+   -enable-kvm -m 256 /tmp/qemu-image
+@end example
+
+Here is what each of these options means:
+
+@table @code
+@item qemu-system-x86_64
+This specifies the hardware platform to emulate.  This should match the
+host.
+
+@item -net user
+Enable the unprivileged user-mode network stack.  The guest OS can access
+the host but not vice versa.  This is the simplest way to get the guest OS
+online.
+
+@item -net nic,model=virtio
+You must create a network interface of a given model.  If you do not create
+a NIC, the boot will fail.  Assuming your hardware platform is x86_64, you
+can get a list of available NIC models by running
+@command{qemu-system-x86_64 -net nic,model=help}.
+
+@item -enable-kvm
+If your system has hardware virtualization extensions, enabling the virtual
+machine support (KVM) of the Linux kernel will make things run faster.
+
+@item -m 256
+RAM available to the guest OS, in mebibytes.  Defaults to 128@tie{}MiB,
+which may be insufficient for some operations.
+
+@item /tmp/qemu-image
+The file name of the qcow2 image.
+@end table
+
+The default @command{run-vm.sh} script that is returned by an invocation of
+@command{guix system vm} does not add a @command{-net user} flag by
+default.  To get network access from within the vm add the
+@code{(dhcp-client-service)} to your system definition and start the VM
+using @command{`guix system vm config.scm` -net user}.  An important caveat
+of using @command{-net user} for networking is that @command{ping} will not
+work, because it uses the ICMP protocol.  You'll have to use a different
+command to check for network connectivity, for example @command{guix
+download}.
+
+@subsubsection Connecting Through SSH
+
+@cindex SSH
+@cindex SSH server
+To enable SSH inside a VM you need to add a SSH server like
+@code{(dropbear-service)} or @code{(lsh-service)} to your VM.  The
+@code{(lsh-service}) doesn't currently boot unsupervised.  It requires you
+to type some characters to initialize the randomness generator.  In addition
+you need to forward the SSH port, 22 by default, to the host.  You can do
+this with
+
+@example
+`guix system vm config.scm` -net user,hostfwd=tcp::10022-:22
+@end example
+
+To connect to the VM you can run
+
+@example
+ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 10022
+@end example
+
+The @command{-p} tells @command{ssh} the port you want to connect to.
+@command{-o UserKnownHostsFile=/dev/null} prevents @command{ssh} from
+complaining every time you modify your @command{config.scm} file and the
+@command{-o StrictHostKeyChecking=no} prevents you from having to allow a
+connection to an unknown host every time you connect.
+
+@subsubsection Using @command{virt-viewer} with Spice
+
+As an alternative to the default @command{qemu} graphical client you can use
+the @command{remote-viewer} from the @command{virt-viewer} package.  To
+connect pass the @command{-spice port=5930,disable-ticketing} flag to
+@command{qemu}.  See previous section for further information on how to do
+this.
+
+Spice also allows you to do some nice stuff like share your clipboard with
+your VM.  To enable that you'll also have to pass the following flags to
+@command{qemu}:
+
+@example
+-device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5
+-chardev spicevmc,name=vdagent,id=vdagent
+-device virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,
+name=com.redhat.spice.0
+@end example
+
+You'll also need to add the @pxref{Verschiedene Dienste, Spice service}.
+
+@node Dienste definieren
+@subsection Dienste definieren

+The previous sections show the available services and how one can combine
+them in an @code{operating-system} declaration.  But how do we define them

+
+@cindex services
+@cindex daemons
+Here we define a @dfn{service} as, broadly, something that extends the
+functionality of the operating system.  Often a service is a process---a
+@dfn{daemon}---started when the system boots: a secure shell server, a Web
+server, the Guix build daemon, etc.  Sometimes a service is a daemon whose
+execution can be triggered by another daemon---e.g., an FTP server started
+by @command{inetd} or a D-Bus service activated by @command{dbus-daemon}.
+Occasionally, a service does not map to a daemon.  For instance, the
+``account'' service collects user accounts and makes sure they exist when
+the system runs; the ``udev'' service collects device management rules and
+makes them available to the eudev daemon; the @file{/etc} service populates
+the @file{/etc} directory of the system.
+
+@cindex service extensions
+GuixSD services are connected by @dfn{extensions}.  For instance, the secure
+shell service @emph{extends} the Shepherd---the GuixSD initialization
+system, running as PID@tie{}1---by giving it the command lines to start and
+stop the secure shell daemon (@pxref{Netzwerkdienste,
+@code{lsh-service}}); the UPower service extends the D-Bus service by
+passing it its @file{.service} specification, and extends the udev service
+by passing it device management rules (@pxref{Desktop-Dienste,
+@code{upower-service}}); the Guix daemon service extends the Shepherd by
+passing it the command lines to start and stop the daemon, and extends the
+account service by passing it a list of required build user accounts
+(@pxref{Basisdienste}).
+
+All in all, services and their ``extends'' relations form a directed acyclic
+graph (DAG).  If we represent services as boxes and extensions as arrows, a
+typical system might provide something like this:
+
+@image{images/service-graph,,5in,Typical service extension graph.}
+
+@cindex system service
+At the bottom, we see the @dfn{system service}, which produces the directory
+containing everything to run and boot the system, as returned by the
+@command{guix system build} command.  @xref{Service-Referenz}, to learn
+about the other service types shown here.  @xref{system-extension-graph, the
+@command{guix system extension-graph} command}, for information on how to
+generate this representation for a particular operating system definition.
+
+@cindex service types
+Technically, developers can define @dfn{service types} to express these
+relations.  There can be any number of services of a given type on the
+system---for instance, a system running two instances of the GNU secure
+shell server (lsh) has two instances of @var{lsh-service-type}, with
+different parameters.
+
+The following section describes the programming interface for service types
+and services.
+
+@node Diensttypen und Dienste
+@subsubsection Diensttypen und Dienste
+
+A @dfn{service type} is a node in the DAG described above.  Let us start
+with a simple example, the service type for the Guix build daemon
+(@pxref{Aufruf des guix-daemon}):
+
+@example
+(define guix-service-type
+  (service-type
+   (name 'guix)
+   (extensions
+    (list (service-extension shepherd-root-service-type guix-shepherd-service)
+          (service-extension account-service-type guix-accounts)
+          (service-extension activation-service-type guix-activation)))
+   (default-value (guix-configuration))))
+@end example
+
+@noindent
+It defines three things:
+
+@enumerate
+@item
+A name, whose sole purpose is to make inspection and debugging easier.
+
+@item
+A list of @dfn{service extensions}, where each extension designates the
+target service type and a procedure that, given the parameters of the
+service, returns a list of objects to extend the service of that type.
+
+Every service type has at least one service extension.  The only exception
+is the @dfn{boot service type}, which is the ultimate service.
+
+@item
+Optionally, a default value for instances of this type.
+@end enumerate
+
+In this example, @var{guix-service-type} extends three services:
+
+@table @var
+@item shepherd-root-service-type
+The @var{guix-shepherd-service} procedure defines how the Shepherd service
+is extended.  Namely, it returns a @code{<shepherd-service>} object that
+defines how @command{guix-daemon} is started and stopped (@pxref{Shepherd-Dienste}).
+
+@item account-service-type
+This extension for this service is computed by @var{guix-accounts}, which
+returns a list of @code{user-group} and @code{user-account} objects
+representing the build user accounts (@pxref{Aufruf des guix-daemon}).
+
+@item activation-service-type
+Here @var{guix-activation} is a procedure that returns a gexp, which is a
+code snippet to run at ``activation time''---e.g., when the service is
+booted.
+@end table
+
+A service of this type is instantiated like this:
+
+@example
+(service guix-service-type
+         (guix-configuration
+           (build-accounts 5)
+           (use-substitutes? #f)))
+@end example
+
+The second argument to the @code{service} form is a value representing the
+parameters of this specific service instance.
+@xref{guix-configuration-type, @code{guix-configuration}}, for information
+about the @code{guix-configuration} data type.  When the value is omitted,
+the default value specified by @code{guix-service-type} is used:
+
+@example
+(service guix-service-type)
+@end example
+
+@var{guix-service-type} is quite simple because it extends other services
+but is not extensible itself.
+
+@c @subsubsubsection Extensible Service Types
+
+The service type for an @emph{extensible} service looks like this:
+
+@example
+(define udev-service-type
+  (service-type (name 'udev)
+                (extensions
+                 (list (service-extension shepherd-root-service-type
+                                          udev-shepherd-service)))
+
+                (compose concatenate)       ;concatenate the list of rules
+                (extend (lambda (config rules)
+                          (match config
+                            (($ <udev-configuration> udev initial-rules)
+                             (udev-configuration
+                              (udev udev)   ;the udev package to use
+                              (rules (append initial-rules rules)))))))))
+@end example
+
+This is the service type for the
+@uref{https://wiki.gentoo.org/wiki/Project:Eudev, eudev device management
+daemon}.  Compared to the previous example, in addition to an extension of
+@var{shepherd-root-service-type}, we see two new fields:
+
+@table @code
+@item compose
+This is the procedure to @dfn{compose} the list of extensions to services of
+this type.
+
+Services can extend the udev service by passing it lists of rules; we
+compose those extensions simply by concatenating them.
+
+@item extend
+This procedure defines how the value of the service is @dfn{extended} with
+the composition of the extensions.
+
+Udev extensions are composed into a list of rules, but the udev service
+value is itself a @code{<udev-configuration>} record.  So here, we extend
+that record by appending the list of rules it contains to the list of
+contributed rules.
+
+@item description
+This is a string giving an overview of the service type.  The string can
+contain Texinfo markup (@pxref{Overview,,, texinfo, GNU Texinfo}).  The
+@command{guix system search} command searches these strings and displays
+them (@pxref{Aufruf von guix system}).
+@end table
+
+There can be only one instance of an extensible service type such as
+@var{udev-service-type}.  If there were more, the @code{service-extension}
+specifications would be ambiguous.
+
+Still here? The next section provides a reference of the programming
+interface for services.
+
+@node Service-Referenz
+@subsubsection Service-Referenz
+
+We have seen an overview of service types (@pxref{Diensttypen und Dienste}).  This section provides a reference on how to manipulate services
+and service types.  This interface is provided by the @code{(gnu services)}
+module.
+
+@deffn {Scheme Procedure} service @var{type} [@var{value}]
+Return a new service of @var{type}, a @code{<service-type>} object (see
+below.)  @var{value} can be any object; it represents the parameters of this
+particular service instance.
+
+When @var{value} is omitted, the default value specified by @var{type} is
+used; if @var{type} does not specify a default value, an error is raised.
+
+For instance, this:
+
+@example
+(service openssh-service-type)
+@end example
+
+@noindent
+is equivalent to this:
+
+@example
+(service openssh-service-type
+         (openssh-configuration))
+@end example
+
+In both cases the result is an instance of @code{openssh-service-type} with
+the default configuration.
+@end deffn
+
+@deffn {Scheme Procedure} service? @var{obj}
+Return true if @var{obj} is a service.
+@end deffn
+
+@deffn {Scheme Procedure} service-kind @var{service}
+Return the type of @var{service}---i.e., a @code{<service-type>} object.
+@end deffn
+
+@deffn {Scheme Procedure} service-value @var{service}
+Return the value associated with @var{service}.  It represents its
+parameters.
+@end deffn
+
+Here is an example of how a service is created and manipulated:
+
+@example
+(define s
+  (service nginx-service-type
+           (nginx-configuration
+            (nginx nginx)
+            (log-directory log-directory)
+            (run-directory run-directory)
+            (file config-file))))
+
+(service? s)
+@result{} #t
+
+(eq? (service-kind s) nginx-service-type)
+@result{} #t
+@end example
+
+The @code{modify-services} form provides a handy way to change the
+parameters of some of the services of a list such as @var{%base-services}
+(@pxref{Basisdienste, @code{%base-services}}).  It evaluates to a list of
+services.  Of course, you could always use standard list combinators such as
+@code{map} and @code{fold} to do that (@pxref{SRFI-1, List Library,, guile,
+GNU Guile Reference Manual}); @code{modify-services} simply provides a more
+concise form for this common pattern.
+
+@deffn {Scheme Syntax} modify-services @var{services} @
+  (@var{type} @var{variable} => @var{body}) @dots{}
+
+Modify the services listed in @var{services} according to the given
+clauses.  Each clause has the form:
+
+@example
+(@var{type} @var{variable} => @var{body})
+@end example
+
+where @var{type} is a service type---e.g., @code{guix-service-type}---and
+@var{variable} is an identifier that is bound within the @var{body} to the
+service parameters---e.g., a @code{guix-configuration} instance---of the
+original service of that @var{type}.
+
+The @var{body} should evaluate to the new service parameters, which will be
+used to configure the new service.  This new service will replace the
+original in the resulting list.  Because a service's service parameters are
+created using @code{define-record-type*}, you can write a succinct
+@var{body} that evaluates to the new service parameters by using the
+@code{inherit} feature that @code{define-record-type*} provides.
+
+@xref{Das Konfigurationssystem nutzen}, for example usage.
+
+@end deffn
+
+Next comes the programming interface for service types.  This is something
+you want to know when writing new service definitions, but not necessarily
+when simply looking for ways to customize your @code{operating-system}
+declaration.
+
+@deftp {Data Type} service-type
+@cindex service type
+This is the representation of a @dfn{service type} (@pxref{Diensttypen und Dienste}).
+
+@table @asis
+@item @code{name}
+This is a symbol, used only to simplify inspection and debugging.
+
+@item @code{extensions}
+A non-empty list of @code{<service-extension>} objects (see below).
+
+@item @code{compose} (default: @code{#f})
+If this is @code{#f}, then the service type denotes services that cannot be
+extended---i.e., services that do not receive ``values'' from other
+services.
+
+Otherwise, it must be a one-argument procedure.  The procedure is called by
+@code{fold-services} and is passed a list of values collected from
+extensions.  It may return any single value.
+
+@item @code{extend} (default: @code{#f})
+If this is @code{#f}, services of this type cannot be extended.
+
+Otherwise, it must be a two-argument procedure: @code{fold-services} calls
+it, passing it the initial value of the service as the first argument and
+the result of applying @code{compose} to the extension values as the second
+argument.  It must return a value that is a valid parameter value for the
+service instance.
+@end table
+
+@xref{Diensttypen und Dienste}, for examples.
+@end deftp
+
+@deffn {Scheme Procedure} service-extension @var{target-type} @
+                              @var{compute} Return a new extension for services of type
+@var{target-type}.  @var{compute} must be a one-argument procedure:
+@code{fold-services} calls it, passing it the value associated with the
+service that provides the extension; it must return a valid value for the
+target service.
+@end deffn
+
+@deffn {Scheme Procedure} service-extension? @var{obj}
+Return true if @var{obj} is a service extension.
+@end deffn
+
+Occasionally, you might want to simply extend an existing service.  This
+involves creating a new service type and specifying the extension of
+interest, which can be verbose; the @code{simple-service} procedure provides
+a shorthand for this.
+
+@deffn {Scheme Procedure} simple-service @var{name} @var{target} @var{value}
+Return a service that extends @var{target} with @var{value}.  This works by
+creating a singleton service type @var{name}, of which the returned service
+is an instance.
+
+For example, this extends mcron (@pxref{Geplante Auftragsausführung}) with an
+additional job:
+
+@example
+(simple-service 'my-mcron-job mcron-service-type
+                #~(job '(next-hour (3)) "guix gc -F 2G"))
+@end example
+@end deffn
+
+At the core of the service abstraction lies the @code{fold-services}
+procedure, which is responsible for ``compiling'' a list of services down to
+a single directory that contains everything needed to boot and run the
+system---the directory shown by the @command{guix system build} command
+(@pxref{Aufruf von guix system}).  In essence, it propagates service
+extensions down the service graph, updating each node parameters on the way,
+until it reaches the root node.
+
+@deffn {Scheme Procedure} fold-services @var{services} @
+                            [#:target-type @var{system-service-type}] Fold @var{services} by propagating
+their extensions down to the root of type @var{target-type}; return the root
+service adjusted accordingly.
+@end deffn
+
+Lastly, the @code{(gnu services)} module also defines several essential
+service types, some of which are listed below.
+
+@defvr {Scheme Variable} system-service-type
+This is the root of the service graph.  It produces the system directory as
+returned by the @command{guix system build} command.
+@end defvr
+
+@defvr {Scheme Variable} boot-service-type
+The type of the ``boot service'', which produces the @dfn{boot script}.  The
+boot script is what the initial RAM disk runs when booting.
+@end defvr
+
+@defvr {Scheme Variable} etc-service-type
+The type of the @file{/etc} service.  This service is used to create files
+under @file{/etc} and can be extended by passing it name/file tuples such
+as:
+
+@example
+(list `("issue" ,(plain-file "issue" "Welcome!\n")))
+@end example
+
+In this example, the effect would be to add an @file{/etc/issue} file
+pointing to the given file.
+@end defvr
+
+@defvr {Scheme Variable} setuid-program-service-type
+Type for the ``setuid-program service''.  This service collects lists of
+executable file names, passed as gexps, and adds them to the set of
+setuid-root programs on the system (@pxref{Setuid-Programme}).
+@end defvr
+
+@defvr {Scheme Variable} profile-service-type
+Type of the service that populates the @dfn{system profile}---i.e., the
+programs under @file{/run/current-system/profile}.  Other services can
+extend it by passing it lists of packages to add to the system profile.
+@end defvr
+
+
+@node Shepherd-Dienste
+@subsubsection Shepherd-Dienste
+
+@cindex shepherd services
+@cindex PID 1
+@cindex init system
+The @code{(gnu services shepherd)} module provides a way to define services
+managed by the GNU@tie{}Shepherd, which is the GuixSD initialization
+system---the first process that is started when the system boots, also known
+as PID@tie{}1 (@pxref{Einführung,,, shepherd, The GNU Shepherd Manual}).
+
+Services in the Shepherd can depend on each other.  For instance, the SSH
+daemon may need to be started after the syslog daemon has been started,
+which in turn can only happen once all the file systems have been mounted.
+The simple operating system defined earlier (@pxref{Das Konfigurationssystem nutzen}) results in a service graph like this:
+
+@image{images/shepherd-graph,,5in,Typical shepherd service graph.}
+
+You can actually generate such a graph for any operating system definition
+using the @command{guix system shepherd-graph} command
+(@pxref{system-shepherd-graph, @command{guix system shepherd-graph}}).
+
+The @var{%shepherd-root-service} is a service object representing
+PID@tie{}1, of type @var{shepherd-root-service-type}; it can be extended by
+passing it lists of @code{<shepherd-service>} objects.
+
+@deftp {Data Type} shepherd-service
+The data type representing a service managed by the Shepherd.
+
+@table @asis
+@item @code{provision}
+This is a list of symbols denoting what the service provides.
+
+These are the names that may be passed to @command{herd start},
+@command{herd status}, and similar commands (@pxref{Invoking herd,,,
+shepherd, The GNU Shepherd Manual}).  @xref{Slots of services, the
+@code{provides} slot,, shepherd, The GNU Shepherd Manual}, for details.
+
+@item @code{requirements} (default: @code{'()})
+List of symbols denoting the Shepherd services this one depends on.
+
+@item @code{respawn?} (default: @code{#t})
+Whether to restart the service when it stops, for instance when the
+underlying process dies.
+
+@item @code{start}
+@itemx @code{stop} (default: @code{#~(const #f)})
+The @code{start} and @code{stop} fields refer to the Shepherd's facilities
+to start and stop processes (@pxref{Service De- and Constructors,,,
+shepherd, The GNU Shepherd Manual}).  They are given as G-expressions that
+get expanded in the Shepherd configuration file (@pxref{G-Ausdrücke}).
+
+@item @code{actions} (default: @code{'()})
+@cindex actions, of Shepherd services
+This is a list of @code{shepherd-action} objects (see below) defining
+@dfn{actions} supported by the service, in addition to the standard
+@code{start} and @code{stop} actions.  Actions listed here become available
+as @command{herd} sub-commands:
+
+@example
+herd @var{action} @var{service} [@var{arguments}@dots{}]
+@end example
+
+@item @code{Dokumentation}
+A documentation string, as shown when running:
+
+@example
+herd doc @var{service-name}
+@end example
+
+where @var{service-name} is one of the symbols in @var{provision}
+(@pxref{Invoking herd,,, shepherd, The GNU Shepherd Manual}).
+
+@item @code{modules} (default: @var{%default-modules})
+This is the list of modules that must be in scope when @code{start} and
+@code{stop} are evaluated.
+
+@end table
+@end deftp
+
+@deftp {Data Type} shepherd-action
+This is the data type that defines additional actions implemented by a
+Shepherd service (see above).
+
+@table @code
+@item name
+Symbol naming the action.
+
+@item Dokumentation
+This is a documentation string for the action.  It can be viewed by running:
+
+@example
+herd doc @var{service} action @var{action}
+@end example
+
+@item procedure
+This should be a gexp that evaluates to a procedure of at least one
+argument, which is the ``running value'' of the service (@pxref{Slots of
+services,,, shepherd, The GNU Shepherd Manual}).
+@end table
+
+The following example defines an action called @code{say-hello} that kindly
+greets the user:
+
+@example
+(shepherd-action
+  (name 'say-hello)
+  (documentation "Say hi!")
+  (procedure #~(lambda (running . args)
+                 (format #t "Hello, friend! arguments: ~s\n"
+                         args)
+                 #t)))
+@end example
+
+Assuming this action is added to the @code{example} service, then you can
+do:
+
+@example
+# herd say-hello example
+Hello, friend! arguments: ()
+# herd say-hello example a b c
+Hello, friend! arguments: ("a" "b" "c")
+@end example
+
+This, as you can see, is a fairly sophisticated way to say hello.
+@xref{Service Convenience,,, shepherd, The GNU Shepherd Manual}, for more
+info on actions.
+@end deftp
+
+@defvr {Scheme Variable} shepherd-root-service-type
+The service type for the Shepherd ``root service''---i.e., PID@tie{}1.
+

+@cindex searching for documentation
+@cindex Info, documentation format
+@cindex man pages
+@cindex manual pages
+In most cases packages installed with Guix come with documentation.  There
+are two main documentation formats: ``Info'', a browseable hypertext format
+used for GNU software, and ``manual pages'' (or ``man pages''), the linear
+documentation format traditionally found on Unix.  Info manuals are accessed
+with the @command{info} command or with Emacs, and man pages are accessed
+using @command{man}.
+
+You can look for documentation of software installed on your system by
+keyword.  For example, the following command searches for information about
+``TLS'' in Info manuals:
+
+@example
+$ info -k TLS
+"(emacs)Network Security" -- STARTTLS
+"(emacs)Network Security" -- TLS
+"(gnutls)Core TLS API" -- gnutls_certificate_set_verify_flags
+"(gnutls)Core TLS API" -- gnutls_certificate_set_verify_function
+@dots{}
+@end example
+
+@noindent
+The command below searches for the same keyword in man pages:
+
+@example
+$ man -k TLS
+SSL (7)              - OpenSSL SSL/TLS library
+certtool (1)         - GnuTLS certificate tool
+@dots {}
+@end example
+
+These searches are purely local to your computer so you have the guarantee
+that documentation you find corresponds to what you have actually installed,
+you can access it off-line, and your privacy is respected.
+
+Once you have these results, you can view the relevant documentation by
+running, say:
+
+@example
+$ info "(gnutls)Core TLS API"
+@end example
+
+@noindent
+or:
+
+@example
+$ man certtool
+@end example
+
+Info manuals contain sections and indices as well as hyperlinks like those
+found in Web pages.  The @command{info} reader (@pxref{Top, Info reader,,
+info-stnd, Stand-alone GNU Info}) and its Emacs counterpart (@pxref{Misc
+Help,,, emacs, The GNU Emacs Manual}) provide intuitive key bindings to
+navigate manuals.  @xref{Getting Started,,, info, Info: An Introduction},

+
+@cindex debugging files
+Program binaries, as produced by the GCC compilers for instance, are
+typically written in the ELF format, with a section containing
+@dfn{debugging information}.  Debugging information is what allows the
+debugger, GDB, to map binary code to source code; it is required to debug a
+compiled program in good conditions.
+
+The problem with debugging information is that is takes up a fair amount of
+disk space.  For example, debugging information for the GNU C Library weighs
+in at more than 60 MiB.  Thus, as a user, keeping all the debugging info of
+all the installed programs is usually not an option.  Yet, space savings
+should not come at the cost of an impediment to debugging---especially in
+the GNU system, which should make it easier for users to exert their
+computing freedom (@pxref{GNU-Distribution}).
+
+Thankfully, the GNU Binary Utilities (Binutils) and GDB provide a mechanism
+that allows users to get the best of both worlds: debugging information can
+be stripped from the binaries and stored in separate files.  GDB is then
+able to load debugging information from those files, when they are available
+(@pxref{Separate Debug Files,,, gdb, Debugging with GDB}).
+
+The GNU distribution takes advantage of this by storing debugging
+information in the @code{lib/debug} sub-directory of a separate package
+output unimaginatively called @code{debug} (@pxref{Pakete mit mehreren Ausgaben.}).  Users can choose to install the @code{debug} output of a package
+when they need it.  For instance, the following command installs the
+debugging information for the GNU C Library and for GNU Guile:
+
+@example
+guix package -i glibc:debug guile:debug
+@end example
+
+GDB must then be told to look for debug files in the user's profile, by
+setting the @code{debug-file-directory} variable (consider setting it from
+the @file{~/.gdbinit} file, @pxref{Startup,,, gdb, Debugging with GDB}):
+
+@example
+(gdb) set debug-file-directory ~/.guix-profile/lib/debug
+@end example
+
+From there on, GDB will pick up debugging information from the @code{.debug}
+files under @file{~/.guix-profile/lib/debug}.
+
+In addition, you will most likely want GDB to be able to show the source
+code being debugged.  To do that, you will have to unpack the source code of
+the package of interest (obtained with @code{guix build --source},
+@pxref{Aufruf von guix build}), and to point GDB to that source directory
+using the @code{directory} command (@pxref{Source Path, @code{directory},,
+gdb, Debugging with GDB}).
+
+@c XXX: keep me up-to-date
+The @code{debug} output mechanism in Guix is implemented by the
+@code{gnu-build-system} (@pxref{Erstellungssysteme}).  Currently, it is
+opt-in---debugging information is available only for the packages with
+definitions explicitly declaring a @code{debug} output.  This may be changed
+to opt-out in the future if our build farm servers can handle the load.  To
+check whether a package has a @code{debug} output, use @command{guix package
+--list-available} (@pxref{Aufruf von guix package}).

+@quotation Anmerkung
+As of version @value{VERSION}, the feature described below is considered
+``beta''.
+@end quotation
+
+Guix follows a functional package management discipline
+(@pxref{Einführung}), which implies that, when a package is changed,
+@emph{every package that depends on it} must be rebuilt.  This can
+significantly slow down the deployment of fixes in core packages such as
+libc or Bash, since basically the whole distribution would need to be
+rebuilt.  Using pre-built binaries helps (@pxref{Substitute}), but
+deployment may still take more time than desired.
+
+@cindex grafts
+To address this, Guix implements @dfn{grafts}, a mechanism that allows for
+fast deployment of critical updates without the costs associated with a
+whole-distribution rebuild.  The idea is to rebuild only the package that
+needs to be patched, and then to ``graft'' it onto packages explicitly
+installed by the user and that were previously referring to the original
+package.  The cost of grafting is typically very low, and order of
+magnitudes lower than a full rebuild of the dependency chain.
+
+@cindex replacements of packages, for grafts
+For instance, suppose a security update needs to be applied to Bash.  Guix
+developers will provide a package definition for the ``fixed'' Bash, say
+@var{bash-fixed}, in the usual way (@pxref{Pakete definieren}).  Then, the
+original package definition is augmented with a @code{replacement} field
+pointing to the package containing the bug fix:
+
+@example
+(define bash
+  (package
+    (name "bash")
+    ;; @dots{}
+    (replacement bash-fixed)))
+@end example
+
+From there on, any package depending directly or indirectly on Bash---as
+reported by @command{guix gc --requisites} (@pxref{Aufruf von guix gc})---that
+is installed is automatically ``rewritten'' to refer to @var{bash-fixed}
+instead of @var{bash}.  This grafting process takes time proportional to the
+size of the package, usually less than a minute for an ``average'' package
+on a recent machine.  Grafting is recursive: when an indirect dependency
+requires grafting, then grafting ``propagates'' up to the package that the
+user is installing.
+
+Currently, the length of the name and version of the graft and that of the
+package it replaces (@var{bash-fixed} and @var{bash} in the example above)
+must be equal.  This restriction mostly comes from the fact that grafting
+works by patching files, including binary files, directly.  Other
+restrictions may apply: for instance, when adding a graft to a package
+providing a shared library, the original shared library and its replacement
+must have the same @code{SONAME} and be binary-compatible.
+
+The @option{--no-grafts} command-line option allows you to forcefully avoid
+grafting (@pxref{Gemeinsame Erstellungsoptionen, @option{--no-grafts}}).  Thus, the
+command:
+
+@example
+guix build bash --no-grafts
+@end example
+
+@noindent
+returns the store file name of the original Bash, whereas:
+
+@example
+guix build bash
+@end example
+
+@noindent
+returns the store file name of the ``fixed'', replacement Bash.  This allows
+you to distinguish between the two variants of Bash.
+
+To verify which Bash your whole profile refers to, you can run
+(@pxref{Aufruf von guix gc}):
+
+@example
+guix gc -R `readlink -f ~/.guix-profile` | grep bash
+@end example
+
+@noindent
+@dots{} and compare the store file names that you get with those above.
+Likewise for a complete GuixSD system generation:
+
+@example
+guix gc -R `guix system build my-config.scm` | grep bash
+@end example
+
+Lastly, to check which Bash running processes are using, you can use the
+@command{lsof} command:
+
+@example
+lsof | grep /gnu/store/.*bash
+@end example

+@node Paketmodule
+@section Paketmodule
+
+From a programming viewpoint, the package definitions of the GNU
+distribution are provided by Guile modules in the @code{(gnu packages
+@dots{})} name space@footnote{Note that packages under the @code{(gnu
+packages @dots{})} module name space are not necessarily ``GNU packages''.
+This module naming scheme follows the usual Guile module naming convention:
+@code{gnu} means that these modules are distributed as part of the GNU
+system, and @code{packages} identifies modules that define packages.}
+(@pxref{Module, Guile modules,, guile, GNU Guile Reference Manual}).  For
+instance, the @code{(gnu packages emacs)} module exports a variable named
+@code{emacs}, which is bound to a @code{<package>} object (@pxref{Pakete definieren}).
+
+The @code{(gnu packages @dots{})} module name space is automatically scanned
+for packages by the command-line tools.  For instance, when running
+@code{guix package -i emacs}, all the @code{(gnu packages @dots{})} modules
+are scanned until one that exports a package object whose name is
+@code{emacs} is found.  This package search facility is implemented in the
+@code{(gnu packages)} module.
+
+@cindex Anpassung, von Paketen
+@cindex package module search path
+Users can store package definitions in modules with different names---e.g.,
+@code{(my-packages emacs)}@footnote{Note that the file name and module name
+must match.  For instance, the @code{(my-packages emacs)} module must be
+stored in a @file{my-packages/emacs.scm} file relative to the load path
+specified with @option{--load-path} or @code{GUIX_PACKAGE_PATH}.
+@xref{Modules and the File System,,, guile, GNU Guile Reference Manual}, for
+details.}.  There are two ways to make these package definitions visible to
+the user interfaces:
+
+@enumerate
+@item
+By adding the directory containing your package modules to the search path
+with the @code{-L} flag of @command{guix package} and other commands
+(@pxref{Gemeinsame Erstellungsoptionen}), or by setting the @code{GUIX_PACKAGE_PATH}
+environment variable described below.
+
+@item
+By defining a @dfn{channel} and configuring @command{guix pull} so that it
+pulls from it.  A channel is essentially a Git repository containing package
+modules.  @xref{Channels}, for more information on how to define and use
+channels.
+@end enumerate
+
+@code{GUIX_PACKAGE_PATH} works similarly to other search path variables:
+
+@defvr {Environment Variable} GUIX_PACKAGE_PATH
+This is a colon-separated list of directories to search for additional
+package modules.  Directories listed in this variable take precedence over
+the own modules of the distribution.
+@end defvr
+
+The distribution is fully @dfn{bootstrapped} and @dfn{self-contained}: each
+package is built based solely on other packages in the distribution.  The
+root of this dependency graph is a small set of @dfn{bootstrap binaries},
+provided by the @code{(gnu packages bootstrap)} module.  For more

+@cindex packages, creating
+The GNU distribution is nascent and may well lack some of your favorite
+packages.  This section describes how you can help make the distribution
+grow.  @xref{Mitwirken}, for additional information on how you can help.
+
+Free software packages are usually distributed in the form of @dfn{source
+code tarballs}---typically @file{tar.gz} files that contain all the source
+files.  Adding a package to the distribution means essentially two things:
+adding a @dfn{recipe} that describes how to build the package, including a
+list of other packages required to build it, and adding @dfn{package
+metadata} along with that recipe, such as a description and licensing
+information.
+
+In Guix all this information is embodied in @dfn{package definitions}.
+Package definitions provide a high-level view of the package.  They are
+written using the syntax of the Scheme programming language; in fact, for
+each package we define a variable bound to the package definition, and
+export that variable from a module (@pxref{Paketmodule}).  However,
+in-depth Scheme knowledge is @emph{not} a prerequisite for creating
+packages.  For more information on package definitions, @pxref{Pakete definieren}.
+
+Once a package definition is in place, stored in a file in the Guix source
+tree, it can be tested using the @command{guix build} command
+(@pxref{Aufruf von guix build}).  For example, assuming the new package is
+called @code{gnew}, you may run this command from the Guix build tree
+(@pxref{Guix vor der Installation ausführen}):
+
+@example
+./pre-inst-env guix build gnew --keep-failed
+@end example
+
+Using @code{--keep-failed} makes it easier to debug build failures since it
+provides access to the failed build tree.  Another useful command-line
+option when debugging is @code{--log-file}, to access the build log.
+
+If the package is unknown to the @command{guix} command, it may be that the
+source file contains a syntax error, or lacks a @code{define-public} clause
+to export the package variable.  To figure it out, you may load the module
+from Guile to get more information about the actual error:
+
+@example
+./pre-inst-env guile -c '(use-modules (gnu packages gnew))'
+@end example
+
+Once your package builds correctly, please send us a patch
+(@pxref{Mitwirken}).  Well, if you need help, we will be happy to help
+you too.  Once the patch is committed in the Guix repository, the new
+package automatically gets built on the supported platforms by
+@url{http://hydra.gnu.org/jobset/gnu/master, our continuous integration
+system}.
+
+@cindex substituter
+Users can obtain the new package definition simply by running @command{guix
+pull} (@pxref{Aufruf von guix pull}).  When @code{hydra.gnu.org} is done
+building the package, installing the package automatically downloads
+binaries from there (@pxref{Substitute}).  The only place where human
+intervention is needed is to review and apply the patch.

+@subsection Software-Freiheit
+
+@c Adapted from http://www.gnu.org/philosophy/philosophy.html.
+@cindex free software
+The GNU operating system has been developed so that users can have freedom
+in their computing.  GNU is @dfn{free software}, meaning that users have the
+@url{http://www.gnu.org/philosophy/free-sw.html,four essential freedoms}: to
+run the program, to study and change the program in source code form, to
+redistribute exact copies, and to distribute modified versions.  Packages
+found in the GNU distribution provide only software that conveys these four
+freedoms.
+
+In addition, the GNU distribution follow the
+@url{http://www.gnu.org/distros/free-system-distribution-guidelines.html,free
+software distribution guidelines}.  Among other things, these guidelines
+reject non-free firmware, recommendations of non-free software, and discuss
+ways to deal with trademarks and patents.
+
+Some otherwise free upstream package sources contain a small and optional
+subset that violates the above guidelines, for instance because this subset
+is itself non-free code.  When that happens, the offending items are removed
+with appropriate patches or code snippets in the @code{origin} form of the
+package (@pxref{Pakete definieren}).  This way, @code{guix build --source}
+returns the ``freed'' source rather than the unmodified upstream source.
+
+
+@node Paketbenennung
+@subsection Paketbenennung
+
+@cindex package name
+A package has actually two names associated with it: First, there is the
+name of the @emph{Scheme variable}, the one following @code{define-public}.
+By this name, the package can be made known in the Scheme code, for instance
+as input to another package.  Second, there is the string in the @code{name}
+field of a package definition.  This name is used by package management
+commands such as @command{guix package} and @command{guix build}.
+
+Both are usually the same and correspond to the lowercase conversion of the
+project name chosen upstream, with underscores replaced with hyphens.  For
+instance, GNUnet is available as @code{gnunet}, and SDL_net as
+@code{sdl-net}.
+
+We do not add @code{lib} prefixes for library packages, unless these are
+already part of the official project name.  But @pxref{Python-Module} and
+@ref{Perl-Module} for special rules concerning modules for the Python and
+Perl languages.
+
+Font package names are handled differently, @pxref{Schriftarten}.
+
+
+@node Versionsnummern
+@subsection Versionsnummern
+
+@cindex package version
+We usually package only the latest version of a given free software
+project.  But sometimes, for instance for incompatible library versions, two
+(or more) versions of the same package are needed.  These require different
+Scheme variable names.  We use the name as defined in @ref{Paketbenennung}
+for the most recent version; previous versions use the same name, suffixed
+by @code{-} and the smallest prefix of the version number that may
+distinguish the two versions.
+
+The name inside the package definition is the same for all versions of a
+package and does not contain any version number.
+
+For instance, the versions 2.24.20 and 3.9.12 of GTK+ may be packaged as
+follows:
+
+@example
+(define-public gtk+
+  (package
+    (name "gtk+")
+    (version "3.9.12")
+    ...))
+(define-public gtk+-2
+  (package
+    (name "gtk+")
+    (version "2.24.20")
+    ...))
+@end example
+If we also wanted GTK+ 3.8.2, this would be packaged as
+@example
+(define-public gtk+-3.8
+  (package
+    (name "gtk+")
+    (version "3.8.2")
+    ...))
+@end example
+
+@c See <https://lists.gnu.org/archive/html/guix-devel/2016-01/msg00425.html>,
+@c for a discussion of what follows.
+@cindex version number, for VCS snapshots
+Occasionally, we package snapshots of upstream's version control system
+(VCS) instead of formal releases.  This should remain exceptional, because
+it is up to upstream developers to clarify what the stable release is.  Yet,
+it is sometimes necessary.  So, what should we put in the @code{version}
+field?
+
+Clearly, we need to make the commit identifier of the VCS snapshot visible
+in the version string, but we also need to make sure that the version string
+is monotonically increasing so that @command{guix package --upgrade} can
+determine which version is newer.  Since commit identifiers, notably with
+Git, are not monotonically increasing, we add a revision number that we
+increase each time we upgrade to a newer snapshot.  The resulting version
+string looks like this:
+
+@example
+2.0.11-3.cabba9e
+  ^    ^    ^
+  |    |    `-- upstream commit ID
+  |    |
+  |    `--- Guix package revision
+  |
+latest upstream version
+@end example
+
+It is a good idea to strip commit identifiers in the @code{version} field
+to, say, 7 digits.  It avoids an aesthetic annoyance (assuming aesthetics
+have a role to play here) as well as problems related to OS limits such as
+the maximum shebang length (127 bytes for the Linux kernel.)  It is best to
+use the full commit identifiers in @code{origin}s, though, to avoid
+ambiguities.  A typical package definition may look like this:
+
+@example
+(define my-package
+  (let ((commit "c3f29bc928d5900971f65965feaae59e1272a3f7")
+        (revision "1"))          ;Guix package revision
+    (package
+      (version (git-version "0.9" revision commit))
+      (source (origin
+                (method git-fetch)
+                (uri (git-reference
+                      (url "git://example.org/my-package.git")
+                      (commit commit)))
+                (sha256 (base32 "1mbikn@dots{}"))
+                (file-name (git-file-name name version))))
+      ;; @dots{}
+      )))

+@node Zusammenfassungen und Beschreibungen
+@subsection Zusammenfassungen und Beschreibungen
+
+@cindex package description
+@cindex package synopsis
+As we have seen before, each package in GNU@tie{}Guix includes a synopsis
+and a description (@pxref{Pakete definieren}).  Synopses and descriptions
+are important: They are what @command{guix package --search} searches, and a
+crucial piece of information to help users determine whether a given package
+suits their needs.  Consequently, packagers should pay attention to what
+goes into them.
+
+Synopses must start with a capital letter and must not end with a period.
+They must not start with ``a'' or ``the'', which usually does not bring
+anything; for instance, prefer ``File-frobbing tool'' over ``A tool that
+frobs files''.  The synopsis should say what the package is---e.g., ``Core
+GNU utilities (file, text, shell)''---or what it is used for---e.g., the
+synopsis for GNU@tie{}grep is ``Print lines matching a pattern''.
+
+Keep in mind that the synopsis must be meaningful for a very wide audience.
+For example, ``Manipulate alignments in the SAM format'' might make sense
+for a seasoned bioinformatics researcher, but might be fairly unhelpful or
+even misleading to a non-specialized audience.  It is a good idea to come up
+with a synopsis that gives an idea of the application domain of the
+package.  In this example, this might give something like ``Manipulate
+nucleotide sequence alignments'', which hopefully gives the user a better
+idea of whether this is what they are looking for.
+
+Descriptions should take between five and ten lines.  Use full sentences,
+and avoid using acronyms without first introducing them.  Please avoid
+marketing phrases such as ``world-leading'', ``industrial-strength'', and
+``next-generation'', and avoid superlatives like ``the most
+advanced''---they are not helpful to users looking for a package and may
+even sound suspicious.  Instead, try to be factual, mentioning use cases and
+features.
+
+@cindex Texinfo markup, in package descriptions
+Descriptions can include Texinfo markup, which is useful to introduce
+ornaments such as @code{@@code} or @code{@@dfn}, bullet lists, or hyperlinks
+(@pxref{Overview,,, texinfo, GNU Texinfo}).  However you should be careful
+when using some characters for example @samp{@@} and curly braces which are
+the basic special characters in Texinfo (@pxref{Special Characters,,,
+texinfo, GNU Texinfo}).  User interfaces such as @command{guix package
+--show} take care of rendering it appropriately.
+
+Synopses and descriptions are translated by volunteers
+@uref{http://translationproject.org/domain/guix-packages.html, at the
+Translation Project} so that as many users as possible can read them in
+their native language.  User interfaces search them and display them in the
+language specified by the current locale.
+
+To allow @command{xgettext} to extract them as translatable strings,
+synopses and descriptions @emph{must be literal strings}.  This means that
+you cannot use @code{string-append} or @code{format} to construct these
+strings:
+
+@lisp
+(package
+  ;; @dots{}
+  (synopsis "This is translatable")
+  (description (string-append "This is " "*not*" " translatable.")))
+@end lisp
+
+Translation is a lot of work so, as a packager, please pay even more
+attention to your synopses and descriptions as every change may entail
+additional work for translators.  In order to help them, it is possible to
+make recommendations or instructions visible to them by inserting special
+comments like this (@pxref{xgettext Invocation,,, gettext, GNU Gettext}):
+
+@example
+;; TRANSLATORS: "X11 resize-and-rotate" should not be translated.

+@code{python-2} and @code{python} as explained in @ref{Versionsnummern}.  To
+avoid confusion and naming clashes with other programming languages, it
+seems desirable that the name of a package for a Python module contains the
+word @code{python}.
+
+Some modules are compatible with only one version of Python, others with
+both.  If the package Foo compiles only with Python 3, we name it
+@code{python-foo}; if it compiles only with Python 2, we name it
+@code{python2-foo}. If it is compatible with both versions, we create two
+packages with the corresponding names.
+
+If a project already contains the word @code{python}, we drop this; for
+instance, the module python-dateutil is packaged under the names
+@code{python-dateutil} and @code{python2-dateutil}.  If the project name
+starts with @code{py} (e.g.@: @code{pytz}), we keep it and prefix it as
+described above.
+
+@subsubsection Specifying Dependencies
+@cindex inputs, for Python packages
+
+Dependency information for Python packages is usually available in the
+package source tree, with varying degrees of accuracy: in the
+@file{setup.py} file, in @file{requirements.txt}, or in @file{tox.ini}.
+
+Your mission, when writing a recipe for a Python package, is to map these
+dependencies to the appropriate type of ``input'' (@pxref{„package“-Referenz,
+inputs}).  Although the @code{pypi} importer normally does a good job
+(@pxref{Aufruf von guix import}), you may want to check the following check
+list to determine which dependency goes where.
+
+@itemize
+
+@item
+We currently package Python 2 with @code{setuptools} and @code{pip}
+installed like Python 3.4 has per default.  Thus you don't need to specify
+either of these as an input.  @command{guix lint} will warn you if you do.
+
+@item
+Python dependencies required at run time go into @code{propagated-inputs}.
+They are typically defined with the @code{install_requires} keyword in
+@file{setup.py}, or in the @file{requirements.txt} file.
+
+@item
+Python packages required only at build time---e.g., those listed with the
+@code{setup_requires} keyword in @file{setup.py}---or only for
+testing---e.g., those in @code{tests_require}---go into
+@code{native-inputs}.  The rationale is that (1) they do not need to be
+propagated because they are not needed at run time, and (2) in a
+cross-compilation context, it's the ``native'' input that we'd want.
+
+Examples are the @code{pytest}, @code{mock}, and @code{nose} test
+frameworks.  Of course if any of these packages is also required at
+run-time, it needs to go to @code{propagated-inputs}.
+
+@item
+Anything that does not fall in the previous categories goes to
+@code{inputs}, for example programs or C libraries required for building
+Python packages containing C extensions.
+
+@item
+If a Python package has optional dependencies (@code{extras_require}), it is
+up to you to decide whether to add them or not, based on their
+usefulness/overhead ratio (@pxref{Einreichen von Patches, @command{guix size}}).
+
+@end itemize

+
+@node Perl-Module
+@subsection Perl-Module
+
+@cindex perl
+Perl programs standing for themselves are named as any other package, using
+the lowercase upstream name.  For Perl packages containing a single class,
+we use the lowercase class name, replace all occurrences of @code{::} by
+dashes and prepend the prefix @code{perl-}.  So the class @code{XML::Parser}
+becomes @code{perl-xml-parser}.  Modules containing several classes keep
+their lowercase upstream name and are also prepended by @code{perl-}.  Such
+modules tend to have the word @code{perl} somewhere in their name, which
+gets dropped in favor of the prefix.  For instance, @code{libwww-perl}
+becomes @code{perl-libwww}.
+
+
+@node Java-Pakete
+@subsection Java-Pakete
+
+@cindex java
+Java programs standing for themselves are named as any other package, using
+the lowercase upstream name.
+
+To avoid confusion and naming clashes with other programming languages, it
+is desirable that the name of a package for a Java package is prefixed with
+@code{java-}.  If a project already contains the word @code{java}, we drop
+this; for instance, the package @code{ngsjava} is packaged under the name
+@code{java-ngs}.
+
+For Java packages containing a single class or a small class hierarchy, we
+use the lowercase class name, replace all occurrences of @code{.} by dashes
+and prepend the prefix @code{java-}.  So the class @code{apache.commons.cli}
+becomes package @code{java-apache-commons-cli}.
+
+
+@node Schriftarten
+@subsection Schriftarten
+
+@cindex Schriftarten
+For fonts that are in general not installed by a user for typesetting
+purposes, or that are distributed as part of a larger software package, we
+rely on the general packaging rules for software; for instance, this applies
+to the fonts delivered as part of the X.Org system or fonts that are part of
+TeX Live.
+
+To make it easier for a user to search for fonts, names for other packages
+containing only fonts are constructed as follows, independently of the
+upstream package name.
+
+The name of a package containing only one font family starts with
+@code{font-}; it is followed by the foundry name and a dash @code{-} if the
+foundry is known, and the font family name, in which spaces are replaced by
+dashes (and as usual, all upper case letters are transformed to lower
+case).  For example, the Gentium font family by SIL is packaged under the
+name @code{font-sil-gentium}.
+
+For a package containing several font families, the name of the collection
+is used in the place of the font family name.  For instance, the Liberation
+fonts consist of three families, Liberation Sans, Liberation Serif and
+Liberation Mono.  These could be packaged separately under the names
+@code{font-liberation-sans} and so on; but as they are distributed together
+under a common name, we prefer to package them together as
+@code{font-liberation}.
+
+In the case where several formats of the same font family or font collection
+are packaged separately, a short form of the format, prepended by a dash, is
+added to the package name.  We use @code{-ttf} for TrueType fonts,
+@code{-otf} for OpenType fonts and @code{-type1} for PostScript Type 1
+fonts.

+
+@node Bootstrapping
+@section Bootstrapping
+
+@c Adapted from the ELS 2013 paper.
+
+@cindex bootstrapping
+
+Bootstrapping in our context refers to how the distribution gets built
+``from nothing''.  Remember that the build environment of a derivation
+contains nothing but its declared inputs (@pxref{Einführung}).  So there's
+an obvious chicken-and-egg problem: how does the first package get built?
+How does the first compiler get compiled? Note that this is a question of
+interest only to the curious hacker, not to the regular user, so you can
+shamelessly skip this section if you consider yourself a ``regular user''.
+
+@cindex bootstrap binaries
+The GNU system is primarily made of C code, with libc at its core.  The GNU
+build system itself assumes the availability of a Bourne shell and
+command-line tools provided by GNU Coreutils, Awk, Findutils, `sed', and
+`grep'.  Furthermore, build programs---programs that run @code{./configure},
+@code{make}, etc.---are written in Guile Scheme (@pxref{Ableitungen}).
+Consequently, to be able to build anything at all, from scratch, Guix relies
+on pre-built binaries of Guile, GCC, Binutils, libc, and the other packages
+mentioned above---the @dfn{bootstrap binaries}.
+
+These bootstrap binaries are ``taken for granted'', though we can also
+re-create them if needed (more on that later).
+
+@unnumberedsubsec Preparing to Use the Bootstrap Binaries
+
+@c As of Emacs 24.3, Info-mode displays the image, but since it's a
+@c large image, it's hard to scroll.  Oh well.
+@image{images/bootstrap-graph,6in,,Dependency graph of the early bootstrap
+derivations}
+
+The figure above shows the very beginning of the dependency graph of the
+distribution, corresponding to the package definitions of the @code{(gnu
+packages bootstrap)} module.  A similar figure can be generated with
+@command{guix graph} (@pxref{Aufruf von guix graph}), along the lines of:
+
+@example
+guix graph -t derivation \
+  -e '(@@@@ (gnu packages bootstrap) %bootstrap-gcc)' \
+  | dot -Tps > t.ps
+@end example
+
+At this level of detail, things are slightly complex.  First, Guile itself
+consists of an ELF executable, along with many source and compiled Scheme
+files that are dynamically loaded when it runs.  This gets stored in the
+@file{guile-2.0.7.tar.xz} tarball shown in this graph.  This tarball is part
+of Guix's ``source'' distribution, and gets inserted into the store with
+@code{add-to-store} (@pxref{Der Store}).
+
+But how do we write a derivation that unpacks this tarball and adds it to
+the store? To solve this problem, the @code{guile-bootstrap-2.0.drv}
+derivation---the first one that gets built---uses @code{bash} as its
+builder, which runs @code{build-bootstrap-guile.sh}, which in turn calls
+@code{tar} to unpack the tarball.  Thus, @file{bash}, @file{tar}, @file{xz},
+and @file{mkdir} are statically-linked binaries, also part of the Guix
+source distribution, whose sole purpose is to allow the Guile tarball to be
+unpacked.
+
+Once @code{guile-bootstrap-2.0.drv} is built, we have a functioning Guile
+that can be used to run subsequent build programs.  Its first task is to
+download tarballs containing the other pre-built binaries---this is what the
+@code{.tar.xz.drv} derivations do.  Guix modules such as
+@code{ftp-client.scm} are used for this purpose.  The
+@code{module-import.drv} derivations import those modules in a directory in
+the store, using the original layout.  The @code{module-import-compiled.drv}
+derivations compile those modules, and write them in an output directory
+with the right layout.  This corresponds to the @code{#:modules} argument of
+@code{build-expression->derivation} (@pxref{Ableitungen}).
+
+Finally, the various tarballs are unpacked by the derivations
+@code{gcc-bootstrap-0.drv}, @code{glibc-bootstrap-0.drv}, etc., at which
+point we have a working C tool chain.
+
+
+@unnumberedsubsec Building the Build Tools
+
+Bootstrapping is complete when we have a full tool chain that does not
+depend on the pre-built bootstrap tools discussed above.  This no-dependency
+requirement is verified by checking whether the files of the final tool
+chain contain references to the @file{/gnu/store} directories of the
+bootstrap inputs.  The process that leads to this ``final'' tool chain is
+described by the package definitions found in the @code{(gnu packages
+commencement)} module.
+
+The @command{guix graph} command allows us to ``zoom out'' compared to the
+graph above, by looking at the level of package objects instead of
+individual derivations---remember that a package may translate to several
+derivations, typically one derivation to download its source, one to build
+the Guile modules it needs, and one to actually build the package from
+source.  The command:
+
+@example
+guix graph -t bag \
+  -e '(@@@@ (gnu packages commencement)
+          glibc-final-with-bootstrap-bash)' | dot -Tps > t.ps
+@end example
+
+@noindent
+produces the dependency graph leading to the ``final'' C
+library@footnote{You may notice the @code{glibc-intermediate} label,
+suggesting that it is not @emph{quite} final, but as a good approximation,
+we will consider it final.}, depicted below.
+
+@image{images/bootstrap-packages,6in,,Dependency graph of the early
+packages}
+
+@c See <http://lists.gnu.org/archive/html/gnu-system-discuss/2012-10/msg00000.html>.
+The first tool that gets built with the bootstrap binaries is
+GNU@tie{}Make---noted @code{make-boot0} above---which is a prerequisite for
+all the following packages.  From there Findutils and Diffutils get built.
+
+Then come the first-stage Binutils and GCC, built as pseudo cross
+tools---i.e., with @code{--target} equal to @code{--host}.  They are used to
+build libc.  Thanks to this cross-build trick, this libc is guaranteed not
+to hold any reference to the initial tool chain.
+
+From there the final Binutils and GCC (not shown above) are built.  GCC uses
+@code{ld} from the final Binutils, and links programs against the just-built
+libc.  This tool chain is used to build the other packages used by Guix and
+by the GNU Build System: Guile, Bash, Coreutils, etc.
+
+And voilà! At this point we have the complete set of build tools that the
+GNU Build System expects.  These are in the @code{%final-inputs} variable of
+the @code{(gnu packages commencement)} module, and are implicitly used by
+any package that uses @code{gnu-build-system} (@pxref{Erstellungssysteme,
+@code{gnu-build-system}}).
+
+
+@unnumberedsubsec Building the Bootstrap Binaries
+
+@cindex bootstrap binaries
+Because the final tool chain does not depend on the bootstrap binaries,
+those rarely need to be updated.  Nevertheless, it is useful to have an
+automated way to produce them, should an update occur, and this is what the
+@code{(gnu packages make-bootstrap)} module provides.
+
+The following command builds the tarballs containing the bootstrap binaries
+(Guile, Binutils, GCC, libc, and a tarball containing a mixture of Coreutils
+and other basic command-line tools):
+
+@example
+guix build bootstrap-tarballs
+@end example
+
+The generated tarballs are those that should be referred to in the
+@code{(gnu packages bootstrap)} module mentioned at the beginning of this
+section.
+
+Still here? Then perhaps by now you've started to wonder: when do we reach a
+fixed point? That is an interesting question! The answer is unknown, but if
+you would like to investigate further (and have significant computational
+and storage resources to do so), then let us know.
+
+@unnumberedsubsec Reducing the Set of Bootstrap Binaries
+
+Our bootstrap binaries currently include GCC, Guile, etc.  That's a lot of
+binary code! Why is that a problem? It's a problem because these big chunks
+of binary code are practically non-auditable, which makes it hard to
+establish what source code produced them.  Every unauditable binary also
+leaves us vulnerable to compiler backdoors as described by Ken Thompson in
+the 1984 paper @emph{Reflections on Trusting Trust}.
+
+This is mitigated by the fact that our bootstrap binaries were generated
+from an earlier Guix revision.  Nevertheless it lacks the level of
+transparency that we get in the rest of the package dependency graph, where
+Guix always gives us a source-to-binary mapping.  Thus, our goal is to
+reduce the set of bootstrap binaries to the bare minimum.
+
+The @uref{http://bootstrappable.org, Bootstrappable.org web site} lists
+on-going projects to do that.  One of these is about replacing the bootstrap
+GCC with a sequence of assemblers, interpreters, and compilers of increasing
+complexity, which could be built from source starting from a simple and
+auditable assembler.  Your help is welcome!
+
+
+@node Portierung
+@section Porting to a New Platform
+
+As discussed above, the GNU distribution is self-contained, and
+self-containment is achieved by relying on pre-built ``bootstrap binaries''
+(@pxref{Bootstrapping}).  These binaries are specific to an operating system
+kernel, CPU architecture, and application binary interface (ABI).  Thus, to
+port the distribution to a platform that is not yet supported, one must
+build those bootstrap binaries, and update the @code{(gnu packages
+bootstrap)} module to use them on that platform.
+
+Fortunately, Guix can @emph{cross compile} those bootstrap binaries.  When
+everything goes well, and assuming the GNU tool chain supports the target
+platform, this can be as simple as running a command like this one:
+
+@example
+guix build --target=armv5tel-linux-gnueabi bootstrap-tarballs
+@end example
+
+For this to work, the @code{glibc-dynamic-linker} procedure in @code{(gnu
+packages bootstrap)} must be augmented to return the right file name for
+libc's dynamic linker on that platform; likewise,
+@code{system->linux-architecture} in @code{(gnu packages linux)} must be
+taught about the new platform.
+
+Once these are built, the @code{(gnu packages bootstrap)} module needs to be
+updated to refer to these binaries on the target platform.  That is, the
+hashes and URLs of the bootstrap tarballs for the new platform must be added
+alongside those of the currently supported platforms.  The bootstrap Guile
+tarball is treated specially: it is expected to be available locally, and
+@file{gnu/local.mk} has rules to download it for the supported
+architectures; a rule for the new platform must be added as well.
+
+In practice, there may be some complications.  First, it may be that the
+extended GNU triplet that specifies an ABI (like the @code{eabi} suffix
+above) is not recognized by all the GNU tools.  Typically, glibc recognizes
+some of these, whereas GCC uses an extra @code{--with-abi} configure flag
+(see @code{gcc.scm} for examples of how to handle this).  Second, some of
+the required packages could fail to build for that platform.  Lastly, the
+generated binaries could be broken for some reason.

+@cindex inférieurs
+@cindex composition de révisions de Guix
+Parfois vous pourriez avoir à mélanger des paquets de votre révision de Guix
+avec des paquets disponibles dans une révision différente de Guix.  Les
+@dfn{inférieurs} de Guix vous permettent d'accomplir cette tâche en
+composant différentes versions de Guix de manière arbitraire.
+
+@cindex paquets inférieurs
+Techniquement, un « inférieur » est surtout un processus Guix séparé
+connecté à votre processus Guix principal à travers un REPL (@pxref{Invoquer guix repl}).  Le module @code{(guix inferior)} vous permet de créer des
+inférieurs et de communiquer avec eux.  Il fournit aussi une interface de
+haut-niveau pour naviguer dans les paquets d'un inférieur — @dfn{des paquets
+inférieurs} — et les manipuler.
+
+Lorsqu'on les combine avec des canaux (@pxref{Canaux}), les inférieurs
+fournissent une manière simple d'interagir avec un révision de Guix
+séparée.  Par exemple, disons que vous souhaitiez installer dans votre
+profil le paquet guile actuel, avec le @code{guile-json} d'une ancienne
+révision de Guix — peut-être parce que la nouvelle version de
+@code{guile-json} a une API incompatible et que vous voulez lancer du code
+avec l'ancienne API.  Pour cela, vous pourriez écrire un manifeste à
+utiliser avec @code{guix package --manifest} (@pxref{Invoquer guix package})
+; dans ce manifeste, vous créeriez un inférieur pour l'ancienne révision de
+Guix qui vous intéresse et vous chercheriez le paquet @code{guile-json} dans
+l'inférieur :
+
+@lisp
+(use-modules (guix inferior) (guix channels)
+             (srfi srfi-1))   ;pour « first »
+
+(define channels
+  ;; L'ancienne révision depuis laquelle on veut
+  ;; extraire guile-json.
+  (list (channel
+         (name 'guix)
+         (url "https://git.savannah.gnu.org/git/guix.git")
+         (commit
+          "65956ad3526ba09e1f7a40722c96c6ef7c0936fe"))))
+
+(define inferior
+  ;; Un inférieur représentant la révision ci-dessus.
+  (inferior-for-channels channels))
+
+;; Maintenant on crée un manifeste avec le paquet « guile » actuel
+;; et l'ancien paquet « guile-json ».
+(packages->manifest
+ (list (first (lookup-inferior-packages inferior "guile-json"))
+       (specification->package "guile")))
+@end lisp
+
+Durant la première exécution, @command{guix package --manifest} pourrait
+avoir besoin de construire le canal que vous avez spécifié avant de créer
+l'inférieur ; les exécutions suivantes seront bien plus rapides parce que la
+révision de Guix sera déjà en cache.
+
+Le module @code{(guix inferior)} fournit les procédures suivantes pour
+ouvrir un inférieur :
+
+@deffn {Procédure Scheme} inferior-for-channels @var{channels} @
+   [#:cache-directory] [#:ttl]
+Renvoie un inférieur pour @var{channels}, une liste de canaux.  Elle utilise
+le cache dans @var{cache-directory}, où les entrées peuvent être glanées
+après @var{ttl} secondes.  Cette procédure ouvre une nouvelle connexion au
+démon de construction.
+
+Elle a pour effet de bord de construire ou de substituer des binaires pour
+@var{channels}, ce qui peut prendre du temps.
+@end deffn
+
+@deffn {Procédure Scheme} open-inferior @var{directory} @
+  [#:command "bin/guix"]
+Ouvre le Guix inférieur dans @var{directory} et lance
+@code{@var{directory}/@var{command} repl} ou équivalent.  Renvoie @code{#f}
+si l'inférieur n'a pas pu être lancé.
+@end deffn
+
+@cindex paquets inférieurs
+Les procédures listées plus bas vous permettent d'obtenir et de manipuler
+des paquets inférieurs.
+
+@deffn {Procédure Scheme} inferior-packages @var{inferior}
+Renvoie la liste des paquets connus de l'inférieur @var{inferior}.
+@end deffn
+
+@deffn {Procédure Scheme} lookup-inferior-packages @var{inferior} @var{name} @
+   [@var{version}]
+Renvoie la liste triée des paquets inférieurs qui correspondent à @var{name}
+dans @var{inferior}, avec le plus haut numéro de version en premier.  Si
+@var{version} est vrai, renvoie seulement les paquets avec un numéro de
+version préfixé par @var{version}.
+@end deffn

+Ces procédures sont la contrepartie des accesseurs des enregistrements de
+paquets (@pxref{Référence de paquet}).  La plupart fonctionne en effectuant
+des requêtes à l'inférieur dont provient @var{package}, donc l'inférieur
+doit toujours être disponible lorsque vous appelez ces procédures.

+
+Les paquets inférieurs peuvent être utilisés de manière transparente comme
+tout autre paquet ou objet simili-fichier dans des G-expressions
+(@pxref{G-Expressions}).  Ils sont aussi gérés de manière transparente par
+la procédure @code{packages->manifest}, qui est typiquement utilisée dans
+des manifestes (@pxref{Invoquer guix package, l'option @option{--manifest}
+de @command{guix package}}).  Ainsi, vous pouvez insérer un paquet inférieur
+à peu près n'importe où vous utiliseriez un paquet normal : dans des
+manifestes, dans le champ @code{packages} de votre déclaration
+@code{operating-system}, etc.

+@section Invoquer @command{guix processes}
+
+La commande @command{guix processes} peut être utile pour les développeurs

+démarré avec @option{--listen} en spécifiant un point d'entrée TCP, ne sont

+ChildProcess: 27793: guix offload x86_64-linux 7200 1 28800
+@end example
+
+Dans cet exemple, on voit que @command{guix-daemon} a trois clients directs
+: @command{guix environment}, @command{guix publish} et l'outil
+d'intégration continue Cuirass ; leur identifiant de processus (PID) est
+donné par le champ @code{ClientPID}.  Le champ @code{SessionPID} fournit le
+PID du sous-processus @command{guix-daemon} de cette session particulière.
+
+Les champs @code{LockHeld} montrent quels éléments du dépôt sont
+actuellement verrouillés par cette session, ce qui correspond aux éléments
+du dépôt qui sont en train d'être construits ou d'être substitués (le champ
+@code{LockHeld} n'est pas montré si @command{guix processes} n'est pas lancé
+en root).  Enfin, en regardant le champ @code{ChildProcess}, on comprend que
+ces trois constructions sont déchargées (@pxref{Réglages du délestage du démon}).
+
+La sortie est dans le format Recutils pour qu'on puisse utiliser la commande
+@command{recsel} pour sélectionner les sessions qui nous intéressent
+(@pxref{Selection Expressions,,, recutils, GNU recutils manual}).  Par
+exemple, la commande montre la ligne de commande et le PID du client qui
+effectue la construction d'un paquet Perl :

 @cindex fastcgi
 @cindex fcgiwrap
-FastCGI is an interface between the front-end and the back-end of a web
-service.  It is a somewhat legacy facility; new web services should
-generally just talk HTTP between the front-end and the back-end.  However
-there are a number of back-end services such as PHP or the optimized HTTP
-Git repository access that use FastCGI, so we have support for it in Guix.
-
-To use FastCGI, you configure the front-end web server (e.g., nginx) to
-dispatch some subset of its requests to the fastcgi backend, which listens
-on a local TCP or UNIX socket.  There is an intermediary @code{fcgiwrap}
-program that sits between the actual backend process and the web server.
-The front-end indicates which backend program to run, passing that
-information to the @code{fcgiwrap} process.
+FastCGI est une interface entre le frontal et le moteur d'un service web.
+C'est un dispositif quelque peu désué ; les nouveaux services devraient
+généralement juste parler HTTP entre le frontal et le moteur.  Cependant il
+y a un certain nombre de services de moteurs comme PHP ou l'accès aux dépôts
+Git optimisé en HTTP qui utilisent FastCGI, donc nous le supportons dans
+Guix.
+
+Pour utiliser FastCGI, vous configurez le serveur web frontal (p.@: ex.@:
+nginx) pour envoyer un sous-ensemble de ses requêtes au moteur fastcgi, qui
+écoute sur un socket UNIX ou TCP local.  Il y a un programme @code{fcgiwrap}
+intermédiaire qui se trouve entre le processus du moteur et le serveur web.
+Le frontal indique quel moteur lancer, en passant cette information au
+processus @code{fcgiwrap}.

-the specific user or group names @code{fcgiwrap} that the corresponding user
-and/or group is present on the system.
-
-It is possible to configure a FastCGI-backed web service to pass HTTP
-authentication information from the front-end to the back-end, and to allow
-@code{fcgiwrap} to run the back-end process as a corresponding local user.
-To enable this capability on the back-end., run @code{fcgiwrap} as the
-@code{root} user and group.  Note that this capability also has to be
-configured on the front-end as well.
+Les noms de l'utilisateur et du groupe, en tant que chaînes de caractères,

+et de permettre à @code{fcgiwrap} dans lancer le processus de moteur avec
+l'utilisateur correspondant.  Pour activer cette fonctionnalité sur le

 @cindex Let's Encrypt
-@cindex TLS certificates
-The @code{(gnu services certbot)} module provides a service to automatically
-obtain a valid TLS certificate from the Let's Encrypt certificate
-authority.  These certificates can then be used to serve content securely
-over HTTPS or other TLS-based protocols, with the knowledge that the client
-will be able to verify the server's authenticity.
-
-@url{https://letsencrypt.org/, Let's Encrypt} provides the @code{certbot}
-tool to automate the certification process.  This tool first securely
-generates a key on the server.  It then makes a request to the Let's Encrypt
-certificate authority (CA) to sign the key.  The CA checks that the request
-originates from the host in question by using a challenge-response protocol,
-requiring the server to provide its response over HTTP.  If that protocol
-completes successfully, the CA signs the key, resulting in a certificate.
-That certificate is valid for a limited period of time, and therefore to
-continue to provide TLS services, the server needs to periodically ask the
-CA to renew its signature.
+@cindex certificats TLS
+Le module @code{(gnu services certbot)} fournit un service qui récupère
+automatiquement un certificat TLS valide de l'autorité de certification
+Let's Encrypt.  Ces certificats peuvent ensuite être utilisés pour servir du

+en sachant que le client sera capable de vérifier l'authenticité du serveur.

+@url{https://letsencrypt.org/, Let's Encrypt} fournit l'outil @code{certbot}
+pour automatiser le processus de certification.  Cet outil génère d'abord un
+clef sur le serveur de manière sécurisée.  Ensuite il demande à l'autorité
+de certification Let's Encrypt de signer la clef.  La CA vérifie que la
+requête provient de l'hôte en question en utilisant un protocole de
+défi-réponse, ce qui requiert que le serveur fournisse sa réponse par HTTP.
+Si ce protocole se passe sans encombre, la CA signe la clef et on obtient un
+certificat.  Ce certificat est valide pour une durée limitée et donc, pour
+continuer à fournir des services en TLS, le serveur doit régulièrement
+demander à la CA de renouveler sa signature.
 
 The certbot service automates this process: the initial key generation, the
 initial certification request to the Let's Encrypt service, the web server
 challenge/response integration, writing the certificate to disk, the
 automated periodic renewals, and the deployment tasks associated with the
-renewal (e.g. reloading services, copying keys with different permissions).

 @deftp {Type de données} knot-policy-configuration
-Data type representing a dnssec policy.  Knot DNS is able to automatically
-sign your zones.  It can either generate and manage your keys automatically
-or use keys that you generate.
-
-Dnssec is usually implemented using two keys: a Key Signing Key (KSK) that
-is used to sign the second, and a Zone Signing Key (ZSK) that is used to
-sign the zone.  In order to be trusted, the KSK needs to be present in the
-parent zone (usually a top-level domain).  If your registrar supports
-dnssec, you will have to send them your KSK's hash so they can add a DS
-record in their zone.  This is not automated and need to be done each time
-you change your KSK.
-
-The policy also defines the lifetime of keys.  Usually, ZSK can be changed
-easily and use weaker cryptographic functions (they use lower parameters) in
-order to sign records quickly, so they are changed often.  The KSK however
-requires manual interaction with the registrar, so they are changed less
-often and use stronger parameters because they sign only one record.
-
-This type has the following parameters:
+Type de données représentant une politique dnssec.  Knot DNS est capable de
+signer automatiquement vos zones.  Il peut soit générer et gérer vos clefs
+automatiquement ou utiliser des clefs que vous générez.
+
+Dnssec est habituellement implémenté avec deux clefs : une KSK (key signing
+key) qui est utilisé pour signer une seconde, la ZSK (zone signing key) qui
+est utilisée pour signer la zone.  Pour pouvoir être de confiance, la KSK
+doit être présente dans la zone parente (normalement un domaine de haut
+niveau).  Si votre registrar supporte dnssec, vous devrez leur envoyer le
+hash de votre KSK pour qu'il puisse ajouter un enregistrement DS dans la
+zone parente.  Ce n'est pas automatique et vous devrez le faire à chaque
+fois que vous changerez votre KSK.
+
+La politique définie aussi la durée de vie des clefs.  Habituellement, la
+ZSK peut être changée facilement et utilise des fonctions cryptographiques
+plus faibles (avec un paramètre plus faible) pour signer les enregistrements
+rapidement, donc elles sont changées très régulièrement.  La KSK en revanche
+requiert une interaction manuelle avec le registrar, donc elle change moins
+souvent et utilise des paramètres plus robustes puisqu'elle ne signe qu'un
+seul enregistrement.
+
+Ce type a les paramètres suivants :

+the channel repository.

+The meta-data file should contain a simple S-expression like this:

+In this example we see that @command{guix-daemon} has three clients:
+@command{guix environment}, @command{guix publish}, and the Cuirass continuous
+integration tool; their process identifier (PID) is given by the
+@code{ClientPID} field.  The @code{SessionPID} field gives the PID of the
+@command{guix-daemon} sub-process of this particular session.
+
+The @code{LockHeld} fields show which store items are currently locked by this
+session, which corresponds to store items being built or substituted (the
+@code{LockHeld} field is not displayed when @command{guix processes} is not
+running as root.)  Last, by looking at the @code{ChildProcess} field, we
+understand that these three builds are being offloaded (@pxref{Daemon Offload
+Setup}).
+
+The output is in Recutils format so we can use the handy @command{recsel}
+command to select sessions of interest (@pxref{Selection Expressions,,,
+recutils, GNU recutils manual}).  As an example, the command shows the command
+line and PID of the client that triggered the build of a Perl package:

+language with an efficient and robust infrastructure for multithreaded
+programming.  Clojure is a compiled language, yet remains completely dynamic
+– every feature supported by Clojure is supported at runtime.  Clojure
+provides easy access to the Java frameworks, with optional type hints and type
+inference, to ensure that calls to Java can avoid reflection.
+
+Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy
+and a powerful macro system.  Clojure is predominantly a functional programming
+language, and features a rich set of immutable, persistent data structures.
+When mutable state is needed, Clojure offers a software transactional memory
+system and reactive Agent system that ensure clean, correct, multithreaded

-language with an efficient and robust infrastructure for multithreaded

-– every feature supported by Clojure is supported at runtime.  Clojure
-provides easy access to the Java frameworks, with optional type hints and type
-inference, to ensure that calls to Java can avoid reflection.
-
-Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy
-and a powerful macro system.  Clojure is predominantly a functional programming
-language, and features a rich set of immutable, persistent data structures.
-When mutable state is needed, Clojure offers a software transactional memory
-system and reactive Agent system that ensure clean, correct, multithreaded

+generatation as much as possible).
+@item It does support CDATA.
+@item It should support the same character sets as your Common Lisp
+implementation.
+@item It does support XML name spaces.

+Subject: fix_building_with_latest_versions_of_FFmpeg
+
+Some years-old deprecated stuff has now been removed.
+
+Correct solution is probably to use valid defines etc. in own code, but
+this is more FFMEPG maintainer task (since it also may change how old
+FFMPEG we do support...).

+Subject: [PATCH] Allow negative uids/gids in PolkitUnixUser and Group objects
+
+(uid_t) -1 is still used as placeholder to mean "unset". This is OK, since
+there should be no users with such number, see
+https://systemd.io/UIDS-GIDS#special-linux-uids.
+
+(uid_t) -1 is used as the default value in class initialization.
+
+When a user or group above INT32_MAX is created, the numeric uid or
+gid wraps around to negative when the value is assigned to gint, and
+polkit gets confused. Let's accept such gids, except for -1.
+
+A nicer fix would be to change the underlying type to e.g. uint32 to
+not have negative values. But this cannot be done without breaking the
+API, so likely new functions will have to be added (a
+polkit_unix_user_new variant that takes a unsigned, and the same for
+_group_new, _set_uid, _get_uid, _set_gid, _get_gid, etc.). This will
+require a bigger patch.
+
+Fixes https://gitlab.freedesktop.org/polkit/polkit/issues/74.

+Subject: [PATCH] nvme: fix out-of-bounds access to the CMB
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Because the CMB BAR has a min_access_size of 2, if you read the last
+byte it will try to memcpy *2* bytes from n->cmbuf, causing an off-by-one
+error.  This is CVE-2018-16847.
+
+Another way to fix this might be to register the CMB as a RAM memory
+region, which would also be more efficient.  However, that might be a
+change for big-endian machines; I didn't think this through and I don't
+know how real hardware works.  Add a basic testcase for the CMB in case
+somebody does this change later on.

+Allwinner A64 has a I2C controller, which is in the R_ MMIO zone and has

+
+Add support for this I2C controller and the pinmux which doesn't conflict
+with RSB.

+Subject: [PATCH 04/13] sunxi: A64: Re-add syscon to DT node
+
+The sun50i-a64.dtsi changes introduced in Linux v4.19-rc1 changed the
+compatible name for the syscon controller, dropping the generic "syscon"
+fallback. Using this new DT node will make the Ethernet driver in every
+older kernel (or non-Linux kernels) fail to initialise the MAC device.
+
+To allow booting distribution kernels (from installer images via UEFI,
+for instance), re-add the syscon compatible string as a fallback. This
+works with both older and newer kernels.

+and expressing variational forms.  Interfaces to specialized matrix
+solvers are provided for solving the resultant linear systems.

Da sich die entfernte Erstellungsmaschine wahrscheinlich von Ihrer unterscheidet, können Sie auf diese Weise Probleme durch Nichtdeterminismus erkennen, die mit der Hardware zu tun haben — zum Beispiel die Nutzung anderer Befehlssatzerweiterungen — oder mit dem Betriebssystem-Kernel — zum Beispiel, indem @code{uname} oder @file{/proc}-Dateien verwendet werden."

+msgid "Under the hood, Guix implements the @dfn{functional package management} discipline pioneered by Nix (@pxref{Acknowledgments}).  In Guix, the package build and installation process is seen as a @emph{function}, in the mathematical sense.  That function takes inputs, such as build scripts, a compiler, and libraries, and returns an installed package.  As a pure function, its result depends solely on its inputs---for instance, it cannot refer to software or scripts that were not explicitly passed as inputs.  A build function always produces the same result when passed a given set of inputs.  It cannot alter the environment of the running system in any way; for instance, it cannot create, modify, or delete files outside of its build and installation directories.  This is achieved by running build processes in isolated environments (or @dfn{containers}), where only their explicit inputs are visible."
+msgstr "Intern implementiert Guix die Disziplin der @dfn{funktionalen Paketverwaltung}, zu der Nix schon die Pionierarbeit geleistet hat (@pxref{Acknowledgments}). In Guix wird der Prozess, ein Paket zu erstellen und zu installieren, als eine @emph{Funktion} im mathematischen Sinn aufgefasst. Diese Funktion hat Eingaben, wie zum Beispiel Erstellungs-Skripts, einen Compiler und Bibliotheken, und liefert ein installiertes Paket. Als eine reine Funktion hängt sein Ergebnis allein von seinen Eingaben ab — zum Beispiel kann er nicht auf Software oder Skripts Bezug nehmen, die nicht ausdrücklich als Eingaben übergeben wurden. Eine Erstellungsfunktion führt immer zum selben Ergebnis, wenn ihr die gleiche Menge an Eingaben übergeben wurde. Sie kann die Umgebung des laufenden Systems auf keine Weise beeinflussen, zum Beispiel kann sie keine Dateien außerhalb ihrer Erstellungs- und Installationsverzeichnisse verändern. Um dies zu erreichen, laufen Erstellungsprozesse in isolieren Umgebungen (sogenannte @dfn{Container}), wo nur ausdrückliche Eingaben sichtbar sind."

 msgid "Under the hood, Guix implements the @dfn{functional package management} discipline pioneered by Nix (@pxref{Acknowledgments}).  In Guix, the package build and installation process is seen as a @emph{function}, in the mathematical sense.  That function takes inputs, such as build scripts, a compiler, and libraries, and returns an installed package.  As a pure function, its result depends solely on its inputs---for instance, it cannot refer to software or scripts that were not explicitly passed as inputs.  A build function always produces the same result when passed a given set of inputs.  It cannot alter the environment of the running system in any way; for instance, it cannot create, modify, or delete files outside of its build and installation directories.  This is achieved by running build processes in isolated environments (or @dfn{containers}), where only their explicit inputs are visible."
 msgstr "Sous le capot, Guix implémente la discipline de @dfn{gestion de paquet fonctionnel} inventé par Nix (@pxref{Remerciements}).  Dans Guix le processus de construction et d'installation des paquets est vu comme une @emph{fonction} dans le sens mathématique du terme.  Cette fonction a des entrées (comme des scripts de construction, un compilateur et des bibliothèques) et renvoie un paquet installé.  En tant que fonction pure, son résultat ne dépend que de ses entrées.  Par exemple, il ne peut pas faire référence à des logiciels ou des scripts qui n'ont pas été explicitement passés en entrée.  Une fonction de construction produit toujours le même résultat quand on lui donne le même ensemble d'entrée.  Elle ne peut pas modifier l'environnement du système en cours d'exécution d'aucune manière ; par exemple elle ne peut pas créer, modifier ou supprimer des fichiers en dehors de ses répertoires de construction et d'installation.  Ce résultat s'obtient en lançant les processus de construction dans des environnements isolés (ou des @dfn{conteneurs}) où seules les entrées explicites sont visibles."

First, rather than recording all Unix metadata for each file, the nar format only mentions the file type (regular, directory, or symbolic link); Unix permissions and owner/group are dismissed.  Second, the order in which directory entries are stored always follows the order of file names according to the C locale collation order.  This makes archive production fully deterministic."
 msgstr "Les archives sont stockées au format « archive normalisé » ou « nar », qui est comparable dans l'esprit à « tar » mais avec des différences qui le rendent utilisable pour ce qu'on veut faire.

Ensuite, l'ordre dans lequel les entrées de répertoires sont stockés suit toujours l'ordre des noms de fichier dans l'environnement linguistique C.

Monads are a construct that allows two things: associating ``context'' with values (in our case, the context is the store), and building sequences of computations (here computations include accesses to the store).  Values in a monad---values that carry this additional context---are called @dfn{monadic values}; procedures that return such values are called @dfn{monadic procedures}."

Les valeurs dans une monad — les valeurs qui contiennent ce contexte supplémentaire — sont appelées des @dfn{valeurs monadiques} ; les procédures qui renvoient ce genre de valeur sont appelées des @dfn{procédures monadiques}."

 msgid "The Linux kernel has a notion of @dfn{device mapping}: a block device, such as a hard disk partition, can be @dfn{mapped} into another device, usually in @code{/dev/mapper/}, with additional processing over the data that flows through it@footnote{Note that the GNU@tie{}Hurd makes no difference between the concept of a ``mapped device'' and that of a file system: both boil down to @emph{translating} input/output operations made on a file to operations on its backing store.  Thus, the Hurd implements mapped devices, like file systems, using the generic @dfn{translator} mechanism (@pxref{Translators,,, hurd, The GNU Hurd Reference Manual}).}.  A typical example is encryption device mapping: all writes to the mapped device are encrypted, and all reads are deciphered, transparently.  Guix extends this notion by considering any device or set of devices that are @dfn{transformed} in some way to create a new device; for instance, RAID devices are obtained by @dfn{assembling} several other devices, such as hard disks or partitions, into a new one that behaves as one partition.  Other examples, not yet implemented, are LVM logical volumes."
 msgstr "Le noyau Linux a une notion de @dfn{mappage de périphériques} : un périphérique bloc, comme une partition sur un disque dur, peut être @dfn{mappé} sur un autre périphérique, typiquement dans @code{/dev/mapper}, avec des calculs supplémentaires sur les données qui naviguent entre les deux@footnote{Remarquez que le Hurd ne fait pas de différence entre le concept de « périphérique mappé » et celle d'un système de fichiers : les deux correspondent à la @emph{traduction} des opérations d'entrée-sortie faites sur un fichier en des opérations sur ce qui le contient.  Ainsi, le Hurd implémente les périphériques mappés, comme les systèmes de fichiers, avec le mécanisme des @dfn{traducteurs} générique (@pxref{Translators,,, hurd, The GNU Hurd Reference Manual}).}.  Un exemple typique est le mappage de périphériques chiffrés : toutes les écritures sont sur le périphérique mappé sont chiffrées, toutes les lectures déchiffrées, de manière transparente.  Guix étend cette notion en considérant que tout périphérique ou ensemble de périphériques qui sont @dfn{transformés} d'une certaine manière créent un nouveau périphérique ; par exemple, les périphériques RAID sont obtenus en @dfn{assemblant} plusieurs autres périphériques, comme des disque ou des partitions, en un nouveau périphérique en tant qu'unique partition.
