I hope there will be another way of identifying partitions. What happens if the UUID is rooted? You need to be able to regenerate it.
Ext2fs also has volume labels, but of course there's no guarantee that they will be unique. The basic idea is that volume labels are for human usage, whereas UUID's are for programs and as keys to do lookups into a volume database.
What do you mean by "UUID is rooted"? The UUID is stored in the superblock, which is replicated, so once a UUID is assigned, it's rather unlikely it will get smashed. (You could of course lose all of the superblocks, but that's an unusual, exception case sort of thing.)
