breaking out of *n*x jails

One reason to use/require sudo of root commands that I've seen was for auditing the use of root access/commands. It wasn't for security purposes other than yes to give approved people access to priviledged commands using their password and not reveal the root password, however it nicely logs to your logging server that user ran x command. It was a pain yes I wouldn't argue that and the change of habit from admins sudoing to su takes a bit to get out of autopilot mode but it worked out in the end. The other comment was no of course it isn't a security measure or preventing a non-admin from creating an account, however every employer/employee should be getting a nice little motd or security message indicating proper authorized use of the system and lack of expectation to privacy. Creating an administrative account/backdoor would be good grounds to be fired. It's just a security control.
