Hilscher Gesellschaft für Systemautomation mbH
This is a standard linux question and is discussed on many linux newsgroups.
Look into the appropriate manpages (e.g. man getty, man login)
The straightforward way is to write a little shell script (called mylogin in this case)
#!/bin/sh exec login -f root
#
# /etc/inittab
#
# $Id: inittab 1681 2004-09-01 18:12:49Z $
#
console::sysinit:/etc/init.d/rcS
console::respawn:/sbin/getty -n -l /bin/mylogin -L 115200 /dev/ttyNX0 vt100
# Stuff to do before rebooting
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
