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。"

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."

#~ msgstr "Nix，兼容性"

#~ msgid "When a working installation of @url{https://nixos.org/nix/, the Nix package manager} is available, you can instead configure Guix with @code{--disable-daemon}.  In that case, Nix replaces the three dependencies above."
#~ msgstr "当一个已经安装的且可用的@url{https://nixos.org/nix/, Nix包管理器}存在时，你可以为Guix配置@code{--disable-daemon}参数。那样Nix可以替换上面的三个依赖。"

#~ msgid "Guix is compatible with Nix, so it is possible to share the same store between both.  To do so, you must pass @command{configure} not only the same @code{--with-store-dir} value, but also the same @code{--localstatedir} value.  The latter is essential because it specifies where the database that stores metadata about the store is located, among other things.  The default values for Nix are @code{--with-store-dir=/nix/store} and @code{--localstatedir=/nix/var}.  Note that @code{--disable-daemon} is not required if your goal is to share the store with Nix."
#~ msgstr "Guix和Nix兼容，所以两者共享相同的仓库是可行的。如果这样做，你必须传给@command{configure}相同的@code{--with-store-dir}，以及相同的@code{--localstatedir}。后者很重要，因为它指定了储存仓库元数据以及其它信息的数据库的位置，。Nix的默认值是@code{--with-store-dir=/nix/store}和@code{--localstatedir=/nix/var}。注意，如果你的目的是和Nix共享仓库，那么@code{--disable-daemon}参数不是必须的。"
