This section covers both BIOS and UEFI installs. Don't skip it!
Before your newly-created partitions can be used, the block devices that were created in the previous step need to be initialized with filesystem metadata. This process is known as creating a filesystem on the block devices. After filesystems are created on the block devices, they can be mounted and used to store files.
Let's keep this simple. Are you using legacy MBR partitions? If so, let's create an ext2 filesystem on
root # mkfs.ext2 /dev/sda1
If you're using GPT partitions for UEFI, you'll want to create a vfat filesystem on
/dev/sda1, because this is what UEFI is able to read:
root # mkfs.vfat -F 32 /dev/sda1
Now, let's create a swap partition. This partition will be used as disk-based virtual memory for your Funtoo Linux system.
You will not create a filesystem on your swap partition, since it is not used to store files. But it is necessary to initialize it using the
mkswap command. Then we'll run the
swapon command to make your newly-initialized swap space immediately active within the live CD environment, in case it is needed during the rest of the install process:
root # mkswap /dev/sda2 root # swapon /dev/sda2
Now, we need to create a root filesystem. This is where Funtoo Linux will live. We generally recommend ext4 or XFS root filesystems. If you're not sure, choose ext4. Here's how to create a root ext4 filesystem:
root # mkfs.ext4 /dev/sda3
...and here's how to create an XFS root filesystem, if you prefer to use XFS instead of ext4:
root # mkfs.xfs /dev/sda3
Your filesystems (and swap) have all now been initialized, so that that can be mounted (attached to your existing directory heirarchy) and used to store files. We are ready to begin installing Funtoo Linux on these brand-new filesystems.
