I don't know offhand how to set up serial login
Set up the console and output in grub.cfg:
serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1
terminal_input serial
terminal_output serial
Then tell the kernel to use it (grub.cfg, as a kernel parameter):
console=tty0 console=ttyUSB0
Now, you just have to connect another PC to the serial port of your
machine. Reboot, and fire up minicom or something similar, and you'll
get a login screen (and the redirected output).
