Description cambron 1999-09-15 14:23:23 UTC
I entered "linux 1" at the LILO prompt and the system came
up with a bash: prompt for the root user.

I see this as a security issue since this means that any
"linux" system needs physical security.  Anyone can break in
without any tools just by forceing a reboot.

Run level 1 should request a password and the procedure for
getting back a root password should require the "rescue"

Typing linux init=/bin/bash will do the same thing ; if it
bothers you, password protect lilo.
