You can install the package management tool Guix on top of an existing GNU/Linux or GNU/Hurd system4, referred to as a foreign distro. If, instead, you want to install the complete, standalone GNU system distribution, Guix System, see 系统安装. This section is concerned only with the installation of Guix on a foreign distro.
Important: This section only applies to systems without Guix. Following it for existing Guix installations will overwrite important system files.
在foreign distro上安装时，GNU Guix可以在不引起冲突的前提下补充现有的工具。它的数据只存放在两个文件夹里，通常是/gnu/store和/var/guix；系统上的其它文件，如/etc，不会被修改。
一旦安装好了，可以通过运行guix pull升级Guix（see Invoking guix pull）。
