This document will describe fstab stanzas for different filesystems and partitions as standardized in Ubuntu across various things that parse/create/install/consume fstab entries.
device specification
- First mention a comment that an install time it pointed at a named thing, i.e. mpatha, VG name + LV name, Cryptsetup name, raid md0, device name hda2. Then fstab line is specific one in the following order of preferences.
- By-path (on s390x only)
On architectures that support useful by-path links, i.e. /dev/disk/by-path/ccw-0.0.154d-part1
- By-id with uuid
Linux RAID /dev/disk/by-id/md-uuid-2df6ae19:d2b8f232:a92a12e1:ff5884f0-part1
LVM /dev/disk/by-id/dm-uuid-LVM-AW4vtN9Nuh503yw4izneqpuLXCui4dVmXUcfJlf355pxKjolkkDmXJhPuJHZmZhI
Multipath /dev/disk/by-id/dm-uuid-part1-mpath-35000c50015ea71ad
LUKS1 /dev/disk/by-id/dm-uuid-CRYPT-LUKS1-85cd9f053c264a9b919a6cf780818425-foobar
LUKS2 /dev/disk/by-id/dm-uuid-CRYPT-LUKS2-85cd9f053c264a9b919a6cf780818425-foobar
- By-UUID
Things that have UUID, i.e. ext4 /dev/disk/by-uuid/9958d086-4f20-4807-8976-58807a5bc7e0
- By-partuuid
GPT partition /dev/disk/by-partuuid/1de9150c-fbdf-45a1-9c85-930a9bbb6188
- By-path (on s390x only)
On architectures that support useful by-path links, i.e. /dev/disk/by-path/ccw-0.0.154d-part1
- By-device name
/dev/hda2
fs default options
- any: discard
- rootfs: ext4 discard,errors=remount-ro 0 1
- /boot: ext4 discard,noatime,nodiratime 0 2
- /boot/efi: vfat umask=0077 0 1
TODO
- zfs?
- prioritise by-path on z?
