I have to confess to never really using dump just due to not liking the
way it operated and the last time I looked at a dump utility probably
predates ext{2,3,4} or Linux even, but my understanding was that dump
took the whole filesystem with it.  That is, you didn't even need to
mkfs to restore.  You could restore to a block device and that the
restore would lay down the filesystem as it was when it was dumped.

Maybe my memory is just showing it's age.
