Go away?!? Then computers would violate the fundamental law: "A real
server needs only three cords to function: power, ethernet, and
serial." :-)
At a former job when I was installing a lot of machines with serial
consoles, I'd modify the bootloader directive in the kickstart file:
bootloader --location=mbr --append="console=tty0 console=ttyS0"
and use a stock shell routine in the %post section:
#
# serial_console_enable
#
# edit conf files so that /dev/console spews to /dev/ttySx
#
# usage:
# serial_console_enable ttySx (where x is usually 0 or 1)
#
function serial_console_enable {
echo "configuring for serial port on $1 ..."
# 'p' is short for 'port'; test sanity of device name.
local p=$( expr "$1" : 'ttyS\([[:digit:]]\)' )
# bail if $p is empty
if [ -z "$p" ]; then
echo "unknown argument '$1' to serial_console_enable" >&2
return
fi
echo "=> inittab"
echo "con:2345:respawn:/sbin/agetty -h ttyS${p} 9600 vt100" >> /etc/inittab
echo "=> securetty"
echo "ttyS${p}" >> /etc/securetty
echo "=> ioctl.save"
rm -f /etc/ioctl.save
echo "=> grub.conf"
mv /boot/grub/grub.conf /boot/grub/grub.conf.orig
cat <<__eof__ > /boot/grub/grub.conf
# added by kickstart
serial --unit=${p} --speed=9600 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
__eof__
grep -v splashimage /boot/grub/grub.conf.orig >> /boot/grub/grub.conf
echo
} # end serial_console_enable
