Duh... You mean mount wanders off, groping all the disks it can find until
it gets one with the right label?  What if it finds more than one with the
required label?  I don't see how you could enforce a requirement that the
label names be unique (particularly if you have removeable media).

If you let it use the first matching label it finds, aren't you back where
you started?  Also, unless they are *partition* labels (not disk labels),
you couldn't quite do things as in your example (assuming you want more
than one partition per disk).
