>Description:
If you do an install via the serial port, Sysinstall correctly updates
loader.conf so the kernel messages come up on the console. However,
it should also enable a getty on the serial port as well so you can
login to that port. This patch does that by changing "off" to "on "
for ttyd0. Note I do not disable getty on ttyvX. It's probably fairly
easy for the admin to just login as root on the serial port and
disable getty on ttyvX if by chance no display or keyboard device is
available to address that issue.
This should make life a little easier for serial installations.
