[Andrey Korolyov]

kickstart for slave nodes:

bootloader --location=mbr --append="console=ttyS0,9600 console=tty0"

sed -i 's/hiddenmenu/hiddenmenu\n'serial\ --unit=1\ --speed=19200\nterminal\ --timeout=8\ console\ serial/g' /etc/grub.cfg

debian for slave nodes:

in the beginning of late cmd please do

sed -i -e 's/.*GRUB_TERMINAL.*/GRUB_TERMINAL=console/g' -e 's/.*GRUB_GFXMODE.*/#GRUB_GFXMODE=640x480/g' -e 's/.*GRUB_CMDLINE_LINUX.*/GRUB_CMDLINE_LINUX=\"console=tty0 console=ttyS1,9600\"/g' /target/etc/default/grub

May be useful for regular installations too with duplication of isolinux output and installation console to the serial.
