For a (future ) advanced menu:
- disable Extensions/Startup Items. if you install a not
compatible .kext the computer might hang during startup.
For instance Powerlogix CPU director hangs OSX during
startup; has a kext + startup item.
-If a user has an offending login-item set it would be nice
-disable the autologin feature, so you can log-in with root
-disable all loginitems for all users (a bit rude ;-)
