Although the LUKS partition has been initialized, it does not contain a file system yet. Either a new file system needs to be created, or, if an existing Gentoo installation is being encrypted, the full system backup is restored to recreate the original file system on the LUKS partition.
The exact procedure to create or restore the file system depends on which file system is going to be used and/or the backup’s format (if applicable). The following are just some examples:
- Create a single ext4 file system:
# mkfs.ext4 /dev/mapper/gentoo
- Create a Btrfs volume:
# mkfs.btrfs /dev/mapper/gentoo
- Create an LVM physical volume:
# pvcreate /dev/mapper/gentoo
For more information about file system creation, please feel free to consult the relevant section in the Handbook.
Then, unless an LVM physical volume was created, the file system on the LUKS partition can be mounted normally as it was not on a LUKS partition:
# mount /dev/mapper/gentoo /mnt/gentoo
Readers who choose to use LVM on the LUKS partition need to undertake more
steps so that one or more logical volumes are created, and then the logical
volumes that will store the system files for Gentoo can be mounted under
Readers who are restoring a full system backup should also mount the restored
file system to
/mnt/gentoo for subsequent steps.
If a new Gentoo installation is being performed, then please follow the Handbook’s instructions to unpack stage3 to the new file system.
