Okay. I recompiled the kernel on Pliny. I included support for a
serial console (null modem connected to ttyS0 on Larousse). I can get
a login prompt using the serial console, but authentication is failing
for some reason. I am using agetty, which I don't know anything about
configuring. Anybody now of a better getty, or how to properly
configure agetty? I haven't used it while booting up yet (so I don't
know if it is working in that regard). I looked throught the bios
config, and didn't find any remote access or console redirection
config options, so the most we can hope for is console redirection
from the time the kernel loads.

the old kernel is still available (label=linux) in /etc/lilo.conf, in
case we have any trouble with this one.

This probably has to do with agetty not being listed in the PAM configuration,
so it can't access password hashes.

I haven't fiddled with PAM on GNU/Linux, but look in /etc/pam.d or something.

Ahh... A little more looking revealed that I just couldn't log in as
root because the serial port wasn't listed in /etc/securetty.
