Well, if we were going to make this be more general, one other thought
I had was that might be useful to also stash the last hostname in the
superblock. Consider the situation where you have several hundred
fibre-channel disk volumes in your SAN, and where of course the SAN
administrator hasn't done a good job naming them, and of course the
human sysadmins hadn't bothered to use file system labels. If we were
automatically stashing the hostname into the superblock at mount time,
it might help in certain cases after the SAN directory gets smashed,
or some such.
