"dontzap" disabling Terminate_Server XKB?? That was one thing I ran out of time to try (visitors staying and yapping in my ear). Maybe it works if done twice??

Booting into single-mode still allows login as root Editing /etc/passwd:- !root $TheUsualStuff Results in:- "sulogin: cannot open password database" segfault Disallows root login even in single user-mode. Probably not a good idea. Editing /etc/password:- root $TheUsualStuff :/bin/false Disallows root login even in single user-mode.
