While trying to find a way to disable the >console login feature, I found what seems to be an old tip (different site). That tip being, you could disable the >console login by adding a user named ">console" with a secure password.
Sounded good, but doesn't seem to work in Jaguar. However, after tooling around, I found an easier way (which works) to disable the >console login feature. In your favorite text editor (emacs of course), edit the following line in /etc/ttys:
console "/System/Lib...#onoption="/usr/libexec/getty std.9600"[NOTE: The line is much longer than shown here; trimmed for readability. It's line nine in the /etc/ttys file]
