This part assumes you have partitioned your drive in a way that is satisfactory for both you and your computer.

If you are using root on Root on ZFS, chances are you have already formatted your partitions.

Likewise, if you are using Disk encryption, that will influence what you do here.

Root filesystem

The filesystem you choose for the root partition is usually up to you. The typical most common choice of root filesystem is Ext4 or XFS. Chimera does not mandate anything specific.

An example, assuming /dev/sda2 is your root partition:

# mkfs.ext4 /dev/sda2

Boot filesystem

A common case for this is if your root filesystem is not supported by your bootloader, assuming it needs to be. Ext4 is a frequent choice as well, some people use Ext2 and others.

EFI System Partition

The ESP always uses the FAT32 filesystem. Assuming it is /dev/sda1, you can format it like this:

# mkfs.vfat /dev/sda1

PowerPC PReP Boot

POWER systems using this partition do not put any filesystem on it. It is, however, very important for bootloader installation that it is empty.

Assuming it’s /dev/sda1, you should erase it:

# dd if=/dev/zero of=/dev/sda1


Let’s assume you have a swap partition at /dev/sda3. You will want to create your swap space on it like this:

# mkswap /dev/sda3

Other partitions

This is usually up to you.
