# For the Marvell units (and probably many other
# embedded headless ARM devices) we want to open a serial login 
# on ttyS0, which is done in /etc/inittab.
# We also need to be able to login as root ;-)
#
# I'm aware of the possibility that not all "Marvell" units will
# have a serial port that will appear as /dev/ttyS0 in the Linux OS
# but I'll have to deal with those on a case by case basis.
# For the time being let's assume that they all have serial ports.
