Well, I'll give this one some thought.  I see your problem, but I don't
really want to add yet another command line option, nor do I want to add
another dialog, and I'm disinclined to let xfsrestore change ownership and
permissions on a directory it didn't create.

Perhaps what could be done is if you specify a destination directory that
does not exist, xfsrestore could create it and then assign the appropriate
ownership and permissions.  IIRC, at the moment if the destination
directory does not exist, xfsrestore just complains and exits.

Hmm, I'll have to check whether xfsdump even includes the root directory
info in the dump...
