lilo on serial consoles

[Deboo ^]

I'm trying to prepare to give some Linux tests and got a question that
I am confused with, even after digging in to the serial howto and
googling. Can somone give it a try?

2 to 4 seem important to me. 1 is the only option that seems not as
important but then the alias is needed for ttyS0, right? So what could
be the odd one out?


Which one of the following is NOT necessary if you want to be able to
use a serial connection to select a boot image from lilo, to view
kernel and init output, and log in as root?

1. /etc/modules.conf: alias /dev/ttyS0 serial

2. /etc/lilo.conf: serial=0,115200n8

3. /etc/lilo.conf: append="console=ttyS0,115200n8"

4. /etc/securetty: ttyS0

5. /etc/inittab: TO:23:respawn:/sbin/getty -L ttyS0 115200 vt100
