I'm not aware of a guide, but if you do a quick
ls -l /dev/disk/by-uuid
you can find the UUID associated with all your filesystems.
For example:
lrwxrwxrwx 1 root root 10 Feb 11 08:32 0C94B42F94B41BE0 -> ../../sdb1
lrwxrwxrwx 1 root root 10 Feb 11 08:32 1b23f104-df48-4f8e-9003-72da69e6d53b ->
../../dm-8
lrwxrwxrwx 1 root root 10 Feb 11 08:32 2020DF8920DE64F6 -> ../../sda1
lrwxrwxrwx 1 root root 10 Feb 11 08:32 e0acf2fb-def0-40c1-8bc3-9faee7fc8a73 ->
../../sda2
You can then replace the device name with the UUID in your
/etc/fstab:
UUID=e0acf2fb-def0-40c1-8bc3-9faee7fc8a73 /boot ext2 nodev
0 2
In this examples, you can see that /dev/sda2 is my /boot (the
UUID matches in the listing and the fstab). So it should just be a
case of finding the UUID and then replacing the existing device name
with UUID=uuid in /etc/fstab.
If your root filesystem is failing to mount, you might also need to
pass a UUID as the root filesystem on the kernel command line; note
that normally GRUB takes care of all of this for you.
