The snapshot volume does not hold a filesystem - it is just a storage
area for deltas that enable the system to reconstruct a filesystem. 
So you don't need to run xfs utilities on it to make more space.  [But
of course some people might want to run them on writeable snapshots 
(needs kernel patch) for testing the effect of utilities.]
