Come on Ed. This isn't a ufsrestore problem! If folks can get access
to your backup tapes you are hosed. They don't need to use ufsrestore
(setuid or not) to read them. They can just read the raw tape if they
want to and what ever is there. This isn't any agument against
ufsrestore -- it's an argument to physically protect your backup tapes.
