The Funtoo Linux project has transitioned to "Hobby Mode" and this wiki is now read-only.
Install/Download and Extract Stage3/en
| Install Guide, Chapter 8 | < Prev | Next > |
Now that filesystems are created and your hardware and system clock are set, the next step is downloading the initial Stage 3 tarball. The Stage 3 is a pre-compiled system used as a starting point to install Funtoo Linux.
To download the correct build of Funtoo Linux for your system, head over to the Subarches page. Subarches are builds of Funtoo Linux that are designed to run on a particular type of CPU, to offer the best possible performance. They also take advantage of the instruction sets available for each CPU.
If you don't know which subarch to choose, issue this command:
root # gcc -march=native -Q --help=target
The Subarches page lists all CPU-optimized versions of Funtoo Linux. Find the one that is appropriate for the type of CPU that your system has, and then click on its name in the first column (such as corei7, for example.) You will then go to a page dedicated to that subarch, and the stage3s available for download will be listed. If you are using a virtualization technology to run Funtoo Linux, and your VM may migrate to 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 generic image if it may run on both AMD and Intel processors.
For most subarches, you will have several stage3s available to choose from. This next section will help you understand which one to pick.
Which Build?
Pick funtoo-current.
Which Variant?
If you're not sure, pick standard.
Our "regular" stage3's are listed with a variant of standard. The following variant builds are available:
| Variant | Description |
|---|---|
standard | The "standard" version of Funtoo Linux |
pure64 | A 64-bit build that drops multilib (32-bit compatibility) support. Can be ideal for server systems. |
Download the Stage3
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/funtoo-current/x86-64bit/generic_64/stage3-latest.tar.xz
Note that 64-bit systems can run 32-bit or 64-bit stages, but 32-bit systems can only run 32-bit stages. Make sure that you select a Stage 3 build that is appropriate for your CPU. If you are not certain, it is a safe bet to choose the generic_64 or generic_32 stage. Consult the Subarches page for more information.
Once the stage is downloaded, extract the contents with the following command, substituting in the actual name of your Stage 3 tarball:
root # tar xpf stage3-latest.tar.xz
It is very important to use tar's "p" option when extracting the Stage 3 tarball - it tells tar to preserve any permissions and ownership that exists within the archive. Without this option, your Funtoo Linux filesystem permissions will be incorrect.
