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."

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.

The bootstrap Guile tarball is treated specially: it is expected to be available locally, and @file{gnu/local.mk} has rules do download it for the supported architectures; a rule for the new platform must be added as well."

msgid "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."
