How is that different from running a suid-root programme which first
checks if the floppy is "unallocated" (i.e. owner root, and hope that
root doesn't need to use it, or use a separate database: yuk) and then
changes ownerships on the device nodes? You still need to win the
race.
People will still be able to put this in their ~/.login
