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。"

When both are set to @code{yes}, the effect is to keep all the build prerequisites (the sources, compiler, libraries, and other build-time tools) of live objects in the store, regardless of whether these prerequisites are reachable from a GC root.  This is convenient for developers since it saves rebuilds or downloads."
msgstr "这样，设置@code{--gc-keep-derivations}为“yes”使存活性从“输出”传递到“derivation”，设置@code{--gc-keep-outputs}为“yes”使存活性从“derivation”传递到“输出”。当两者都设置为“yes”时，效果是保留所有在仓库里的存活对象的构建先决条件（源代码，编译器，库，和其它构建时的工具），不管这些先决条件是否能从某个GC根访问到。这对开发者来说很方便，因为它避免了重复构建和下载。"

To ``add GNOME'' means that system-level services like the backlight adjustment helpers and the power management utilities are added to the system, extending @code{polkit} and @code{dbus} appropriately, allowing GNOME to operate with elevated privileges on a limited number of special-purpose system interfaces.  Additionally, adding a service made by @code{gnome-desktop-service-type} adds the GNOME metapackage to the system profile.  Likewise, adding the Xfce service not only adds the @code{xfce} metapackage to the system profile, but it also gives the Thunar file manager the ability to open a ``root-mode'' file management window, if the user authenticates using the administrator's password via the standard polkit graphical interface.  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."

Another solution is to use the @code{sddm-service} instead of GDM as the graphical login manager.  You should then select the ``GNOME (Wayland)'' session in SDDM@.
