 msgid "The boundary between using an origin snippet versus a build phase to modify the sources of a package can be elusive.  Origin snippets are typically used to remove unwanted files such as bundled libraries, nonfree sources, or to apply simple substitutions.  The source derived from an origin should produce a source that can be used to build the package on any system that the upstream package supports (i.e., act as the corresponding source).  In particular, origin snippets must not embed store items in the sources; such patching should rather be done using build phases.  Refer to the @code{origin} record documentation for more information (@pxref{origin Reference})."

+msgid "Weblate is backed by a git repository from which it discovers new strings to translate and pushes new and updated translations.  Normally, it would be enough to give it commit access to our repositories.  However, we decided to use a separate repository for two reasons.  First, we would have to give Weblate commit access and authorize its signing key, but we do not trust it in the same way we trust guix developers, especially since we do not manage the instance ourselves.  Second, if translators mess something up, it can break the generation of the website and/or guix pull for all our users, independently of their language."

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。"

 msgid "By default, @command{guix-daemon} launches build processes under different UIDs, taken from the build group specified with @option{--build-users-group}.  In addition, each build process is run in a chroot environment that only contains the subset of the store that the build process depends on, as specified by its derivation (@pxref{Programming Interface, derivation}), plus a set of specific system directories.  By default, the latter contains @file{/dev} and @file{/dev/pts}.  Furthermore, on GNU/Linux, the build environment is a @dfn{container}: in addition to having its own file system tree, it has a separate mount name space, its own PID name space, network name space, etc.  This helps achieve reproducible builds (@pxref{Features})."

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."

Occasionally, a service does not map to a daemon.  For instance, the ``account'' service collects user accounts and makes sure they exist when the system runs; the ``udev'' service collects device management rules and makes them available to the eudev daemon; the @file{/etc} service populates the @file{/etc} directory of the system."

Nevertheless it lacks the level of transparency that we get in the rest of the package dependency graph, where Guix always gives us a source-to-binary mapping.  Thus, our goal is to reduce the set of bootstrap binaries to the bare minimum."

Neither MesCC-Tools nor Mes can be fully bootstrapped yet and thus we inject them as binary seeds.  We call this the Reduced Binary Seed bootstrap, as it has halved the size of our bootstrap binaries! Also, it has eliminated the C compiler binary; i686-linux and x86_64-linux Guix packages are now bootstrapped without any binary C compiler."

These binaries are specific to an operating system kernel, CPU architecture, and application binary interface (ABI).  Thus, to port the distribution to a platform that is not yet supported, one must build those bootstrap binaries, and update the @code{(gnu packages bootstrap)} module to use them on that platform."

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 @option{--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."
