Modify your /etc/inittab. I think you're looking for something like the following:

# What to do in single-user mode.
~~:S:wait:/sbin/sulogin >/dev/tty1 2>&1 </dev/tty1

...

# Format:
# <id>:<runlevels>:<action>:<process>
# 4 virtual consoles with immortal shells
1:12345:respawn:/sbin/getty 38400 tty1
2:2345:respawn:/sbin/getty 38400 tty2
3:2345:respawn:/sbin/getty 38400 tty3
4:2345:respawn:/sbin/getty 38400 tty4


You probably need to tweak the above, but that is the inittab modifications I made to remove autologin on the command line.

I would like this too. After disabling xsession in /etc/inittab, I have had it reboot without pressing return, but I would like to know how to do it in combination with X.
I suspect it's in the Knoppix specific /sbin/init? It's mentioned in /etc/init.d/knoppix-halt. If anyone finds the answer, please post it.
