When you have to do system maintenance, you will have to boot from CD, fix the root account, reboot and do the maintenance. The sysadmin will do the maintenance from a checklist while a large Marine guard with and M16 follows along. When done, scramble the root password.
Boot from CD?!?! Linux single is all you need.
A large Marine guard? Man, this must be a joke post right? Where is the smiley? Bring along a clueless Marine armed with a M16?
