Okay cool...
In /etc/inittab I've got...
S0:2345:respawn:/sbin/getty ttyS0 DT9600 vt102
... for multiuser mode and...
~~:S:wait:/sbin/getty ttyS0 DT9600 vt102
... for single user mode. init seems to ignore the level S entry unless
its by itself. Looking at the source it seems that if there no :S: entry at
all init will fake one like...
~~:S:wait:/bin/bash
... so I'm not sure if the ~~ is madatory. Anwyay - this part works. :)
It's only when I want to use bash instead of getty that I get into trouble.
I have also tried specifing ...
~~:S:wait:/bin/bash < /dev/ttyS0 > /dev/ttyS0 2>&1
... which appears to do the right thing in terms of remapping bash's stdio
but doens't work any better for me.
In /etc/lilo.conf I've got...
boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
serial=0,9600n8
image=/boot/vmlinuz-2.2.16-3_ser505
label=linux-serial
alias=serial
read-only
root=/dev/sda5
append="console=tty0 console=ttyS0,9600"
... which works as advertised. Hope that helps some... :)
