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 "在底层，Guix实现了由Nix（@pxref{Acknowledgments}）开创的@dfn{函数式包管理器}。在Guix里，软件包构建和安装过程被视为数学意义上的@emph{函数}。函数获取输入，如构建脚本、编译器和库，并且返回一个安装好的软件包。作为一个纯函数，它的结果只取决于它的输入－－例如，它不能引用没有作为显式输入传入的软件和脚本。当传入特定的输入时，一个构建函数总是得到相同的结果。它不能以任何方式修改运行系统的环境，例如，它不能创建，修改，或删除构建和安装环境之外的文件夹。这是通过在隔离的环境（@dfn{容器}）里运行构建进程实现的，在这个环境里只能访问到显式的输入。"

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.

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}."

Second, some of the required packages could fail to build for that platform.  Lastly, the generated binaries could be broken for some reason."
