 msgid "When printing the string, Guile replaces the special formatting symbols with actual values.  For instance, the string @samp{ambiguous package specification `~a'} would be substituted to contain said package specification instead of @code{~a}.  To properly translate this string, you must keep the formatting code in your translation, although you can place it where it makes sense in your language.  For instance, the French translation says @samp{spécification du paquet « ~a » ambiguë} because the adjective needs to be placed in the end of the sentence."

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 "Guix takes a @dfn{purely functional} approach to package management, as described in the introduction (@pxref{Introduction}).  Each @file{/gnu/store} package directory name contains a hash of all the inputs that were used to build that package---compiler, libraries, build scripts, etc.  This direct correspondence allows users to make sure a given package installation matches the current state of their distribution.  It also helps maximize @dfn{build reproducibility}: thanks to the isolated build environments that are used, a given build is likely to yield bit-identical files when performed on different machines (@pxref{Invoking guix-daemon, container})."

On a comparable setup, both have the same performance, so one should consider ease of use when deciding between them.  Partitions are ``simpler'' and do not need file system support, but need to be allocated at disk formatting time (logical volumes notwithstanding), whereas files can be allocated and deallocated at any time."

The Linux kernel needs to know about the swap space to be used to resume from hibernation on boot (@i{via} a kernel argument).

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 of type @code{mate-desktop-service-type} 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 expected."

It then makes a request to the Let's Encrypt certificate authority (CA) to sign the key.  The CA checks that the request originates from the host in question by using a challenge-response protocol, requiring the server to provide its response over HTTP@.  If that protocol completes successfully, the CA signs the key, resulting in a certificate.  That certificate is valid for a limited period of time, and therefore to continue to provide TLS services, the server needs to periodically ask the CA to renew its signature."

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."
