As Felix pointed out in this thread, you're possibly talking about
(file system) LABELS. The idea of UUIDs is that they are "unique",
so you can run two OS installs automatically without the disk IDs
colliding. We leave the collision probability of UUIDs as an exercise
for the reader. Suffice it to say that the probability of /very
weird/ things happening (let alone an alpha particle flipping a few
bits in your RAM) is higher than a UUID collision.

A label is something you come up to slap onto something. So using
the same label is most of the time intended.

Of course, this UUID uniqueness thing starts looking ever more
flimsy once you start bit-copying file systems (people do this!
I know I do!).

Civilised file systems have a slot for each, so you can use both
of them, at the same time, for different purposes.

Cheers
