One thing that I have done on single-floppy boot disks is to skip the
whole login thing entirely and just start a shell on the console and
on the first serial port.
Inittab looks like this...
-----------------------------------
#
# Minimal inittab for booting
#
id:2:initdefault:
si::sysinit:/etc/rc.sysinit
1:12345:respawn:/etc/rc.console
2:12345:respawn:/etc/rc.ttyS0
-----------------------------------
rc.sysinit Looks like this
----------------------------------
/sbin/ldconfig
/bin/mount -av
echo "rc.sysinit" > /dev/console
stty sane < /dev/ttyS0
echo "rc.sysinit" > /dev/ttyS0
---------------------------------
And rc.ttyS0 looks like this
-------------------------------
echo "Debug Console now Active (tty0)" > /dev/ttyS0
/bin/sh < /dev/ttyS0 > /dev/ttyS0 2>&1
--------------------------------
Hope this helps.
