Well, that's the problem isn't it.  If the partitions are mounted, I 
probably know what's up with them already.

My problem comes in a system with a variety of hot-swappable devices 
which I may not know at any given time to what device they are assigned. 
  I'de like to be able to say, 'which of these many devices holds a 
partition with a file system labelled x?'  Obviously mount knows how to 
find this information, so it probably isn't difficult.  In fact, I use 
mount to find the information now, but I would really like to do it 
without mounting and would also like to be able to see when two file 
systems have the same label.
