Use the 4.3BSD branch. In these systems, I've set the serial ports
as insecure in /etc/ttys, so people can't login as root. Then, remove
all users from the password file (with vipw) except root and uucp. Or,
keep one non-root user for you to login as.

If you leave vax780 running in 'screen', you can still login as root there.

Cheers, Warren
