Yes. I seemed to have been spreading misinformation. I had been led to
believe that part of the UUID incorporated a hard-identifier/serial
for a given disk, but if that is not the case then it doesn't seem
much more useful than LABEL.


That being said, do drive incorporate some sort of hard serial that
can be read (and how to do so)?
