现在我们已经完成了创建分区以及设置系统时间这两个步骤，下一步便是下载 Stage 3 压缩包。Stage 3 压缩包是一个预编译的，可以作为安装 Funtoo Linux 的出发点的系统。
请移步至 Subarches 来为你的系统下载最新版本的 Funtoo Linux。其他平台的分支（例如 arm 等）是为了让 Funtoo Linux 能在某一特定的 CPU 平台上有最好的表现而设计的。它们也对于每个 CPU 的指令集有不同的优势。
From the subarch list at Subarches, choose your desired level of optimization. A system built specifically for your CPU will run faster than a less-optimized system. For a modern Intel or AMD system, it is safe to pick the exact optimization level for your particular family of CPU. This will offer the best possible performance.
If you are using a virtualization technology to run Funtoo Linux and your VM may be used on different types of hardware, then it's recommended that you use a stage3 that is optimized for the oldest CPU instruction set that your VM will run on, or a more generic image if it may run on both AMD and Intel processors.
Once you have found the appropriate subarch at Subarches, you will likely have a few installation images to choose from. This next section will help you understand which one to pick.
You can always manually choose an installation image via https://build.funtoo.org as well as using the Subarches page. Here is some guidance on choosing the best
.tar.xz image for download. When choosing an image:
- This is release 1.4 of Funtoo Linux, our current release.
- Pick the subarch for the CPU family of the system you are installing on.
- This will provide the best performance.
stage3is a more traditional, minimal and non-graphical installation of Funtoo. You will then build your system up to your desired state using
gnomeinstallation image, if available, includes the full GNOME environment as well as Firefox already optimized for your hardware. You can then continue to further customize your system after installation.
lxdimage is for use with LXD, and is not used for installing directly on a desktop or laptop, so you should not select this option for regular installs. To install, first download and then
lxc image import <name>.tar.xz --alias funtooand then you can
lxc launch funtoo my_container.
Once you have found the stage3 that you would like to download, use
wget to download the Stage 3 tarball you have chosen to use as the basis for your new Funtoo Linux system. It should be saved to the
/mnt/funtoo directory as follows:
root # cd /mnt/funtoo root # wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz
Verify downloaded tarball
Funtoo Linux stage tarballs are signed using GPG by the build server they are built on. It's a good practice to verify authenticity and integrity of downloaded files when possible. For instructions how to import and trust GPG keys check our wiki page about GPG signatures.
Then, you can download the stage3's GPG signature and use the
gpg --verify command in order to verify your tarball:
root # wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz.gpg root # gpg --verify stage3-latest.tar.xz.gpg stage3-latest.tar.xz
Once the stage is downloaded and verified, extract the contents with the following command, substituting in the actual name of your Stage 3 tarball:
root # tar --numeric-owner --xattrs --xattrs-include='*' -xpf stage3-latest.tar.xz
It is very important to use all the options included above. See below for details.
Here are what the options to
- Without this option,
tarwill map ownership and group ownership based on the UID to user and GID to group mappings as defined on the LiveCD. We don't want this -- we want the numeric values of the UIDs and GIDs in the tarball to be preserved on disk, so when your Funtoo Linux system boots, the UIDs and GIDs are set correctly for Funtoo. That is what this option tells
- Funtoo Linux uses filesystem extended attributes to set Linux capabilities, which allow for certain programs such as
pingto have enhanced privileges without having to be fully 'suid root'. Even with the
tarwill not restore extended attributes we need unless these two options are specified.
- This instructs
tarto extract (
