No, it's not (at least in this case).  It's a unique identifier to a
_filesystem_.  Which is why I find changing the fstab this way to be not a
great idea.

aiui, this change was made so that fstab wouldn't break when they
changed /dev/hd* to /dev/sd* - but now it will break any time you reformat
a partition.
