serial console on feisty server

[Tomoki Taniguchi]

you are not starting anything up on the /dev/ttyS0 which is the serial console.

instead of editting /etc/event.d/tty1 and tty2
(these are virtual console running on /dev/tty1 and /dev/tty2 which
corresponds to
CTRL-ALT-F1 and CTRL-ALT-F2 virtual consoles.)
you need to copy /etc/event.d/tty to /etc/event.d/ttyS0
edit the new file and replace the last line
"exec /sbin/getty 38400 tty1"
with
"exec /sbin/getty 9600 ttyS0"
save the file and reboot
you should get a login prompt when the system finishes booting
