That mostly works too, except many shops like to say "exactly 1 UID 0 account" in /etc/passwd - it's a lot easier to flag "there must be exactly one" than "there should be exactly as many as however many people have root access this week". Makes lots of fun at 3AM when the system-check cronjob runs and says there's 6 users where there should be 5 :) -------------- next part -------------- A non-text attachment was scrubbed...
