Without persisted inode numbers (UniqueId) it would cause problems
with hardlinks (ie mounting with noserverino).  We could try a trick
of hashing them with the volume id if we could detect the transition
to a different volume (as original thread was discussing) -
fortunately in Linux you have to walk a path component by component so
might be possible to spot these more easily.
