This is probably another thing which perhaps Ric Wheeler's proposed
"generic LVM / file system management front end" should abstract away,
since every single file system has a different way of setting the UUID
in an off-line way. It's a relatively specialized feature, so I
wouldn't call it high priority to implement first.
