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."

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.

msgstr "Guix se base sur le @uref{http://nixos.org/nix/, gestionnaire de paquets Nix} conçu et implémenté par Eelco Dolstra, avec des constributions d'autres personnes (voir le fichier @file{nix/AUTHORS} dans Guix).  Nix a inventé la gestion de paquet fonctionnelle et promu des fonctionnalités sans précédents comme les mises à jour de paquets transactionnelles et les retours en arrière, les profils par utilisateurs et les processus de constructions transparents pour les références.  Sans ce travail, Guix n'existerait pas."
