That's the easy part.
Column 1 in /etc/fstab identifies which partition is to be mounted.
Identifiers need to be unique.
Device names in /dev/ are no longer stable, they can and do move around
and change.
User-defined labels are a good choice but users can and do re-use the
same labels.
All filesystems generate a GUID for themselves and these are guaranteed
to be unique in the universe, so simply put it in column 1 and mount
will never ever get it wrong.
Ubuntu takes this approach to be able to give guarantees about
installers. It works well. Until you find you want to edit fstab by
hand.
I installed Kubuntu for my brother and I noticed it uses UUID in fstab
too. I also like that it commented where the partition was when Kubuntu
was originally installed. That helps if you chroot in and are not sure
what partition is what but found the fstab file, most likely / at that
point. Then you can mount whatever is listed in fstab using UUID or the
regular device names if nothing has changed.
I might add, if you chose to use UUID, man blkid will be your friend.
