As the saying goes, try typing that fast ten times.... and see how many times the UUID ends up being fat-fignered.

Unless the UUID contains spellable words that use only the hex digits (like deadbeef, cafebabe, or similar). (you can find a list of 1196 hex words at http://nedbatchelder.com/text/hexwords.html )

Mnemonics are essential for jogging the memory... oh, wait....

"Now, was that filesystem with the backup copy of that priceless one-in-a-lifetime video c491d94e-7004-4b08-9993-4c9a7a25b6b1 or was it bb6c2bb9-f01e-3135-a8de-9f885a7afdef or maybe it was f82ffa31-2587-3db8-970a-36e54e72621b... oh, I don't remember!"

But I guess if you physically label the disk with the partitioning and the UUID's of each filesystem, it might be workable.

Too bad many, if not most, drive serial numbers are not spellable in hex....
