2529 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."
2530 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.

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."
