+
+@quotation Caveats
+This information is necessary to rebuild your operating system, but it
+is not always sufficient.  In particular, @file{configuration.scm}
+itself is insufficient if it is not self-contained---if it refers to
+external Guile modules or to extra files.  If you want
+@file{configuration.scm} to be self-contained, we recommend that modules
+or files it refers to be part of a channel.
+
+Besides, provenance meta-data is ``silent'' in the sense that it does
+not change the bits contained in your system, @emph{except for the
+meta-data bits themselves}.  Two different OS configurations or sets of
+channels can lead to the same system, bit-for-bit; when
+@code{provenance-service-type} is used, these two systems will have
+different meta-data and thus different store file names, which makes
+comparison less trivial.
+@end quotation
+
+This service is automatically added to your operating system
+configuration when you use @command{guix system reconfigure},
+@command{guix system init}, or @command{guix deploy}.

+    (description "KSudoku is a Sudoku game and solver, supporting a range of
+2D and 3D Sudoku variants.  In addition to playing Sudoku, it can print Sudoku
+puzzle sheets and find the solution to any Sudoku puzzle.
+
+The word Sudoku means \"single number in an allotted place\" in Japanese.
+These are the basic rules: Every Sudoku is a square divided into 3x3
+subsquares with 3x3 cells each.
+
+Some cells are filled with a number at the beginning.  The remaining ones are
+to be filled by the player using numbers from 1 to 9, without repeating a
+number twice on each column, row or subsquare (each of them must contain only
+one 1, one 2, one 3, and so on).  The game requires logic and patience.
+Solving takes usually 10 to 30 minutes, depending on puzzle level, your skill
+and experience.
+
+The numerals in Sudoku puzzles are used for convenience (for example in 16x16
+board we use letters): arithmetic relationships between numbers are
+irrelevant.
+
+This program supports also 16x16 games with numbers from 1 to 16 and 256
+cells with 16 cols, rows and subsquares!

+Patch taken from Debian sid.
+
+Description: Support uncompressing and compressing soft links.
+ Historically, ncompress for Debian has been built using a command line
+ directly in debian/rules.  For 4.2.4.5-1, I simplified by swtching to the
+ upstream Makefile.  However, that caused a regression - the Debian version of
+ ncompress has always successfully handled soft links, but this stopped
+ working.  To revert to the original behavior, I need to remove -DLSTAT from
+ the build options, to be consistent with how the code was previously built.
