The partition *type* UUID is what's specified in the BLS etc., and everybody's EFI partition will have the same partition type UUID, everybody's /boot partition (if present) should have the same UUID, etc. It's what's translated by parted and the like into 'ext4', 'fat16', etc., rather than displaying the 36 character or so string. But the just-*partition* UUID is for identifying that particular partition, to distinguish it from any other, and no two should ever be the same (this has bitten me a few times when cloning disks). And on top of that, there's often also a filesystem UUID, which should also never be the same (and has also bitten me a few times when dd'ing partition images). Either of the latter two can be used in fstab to identify that particular partition, I believe much more commonly the filesystem UUID, and that's what you see in your fstab there, rather than the partition type UUID. So there's nothing to worry about with it not looking anything like the BLS partition type UUIDs. (Apologies if the formatting goes pear-shaped, I tried tidying up the quotes a bit.) -- J.
