In 5.1 thru 5.3 I have needed to add the following to my %post section to achieve what you are looking to do. I have kept this option in the 5.4 installs as I haven't seen any problems. # modify inittab to add serial console login cat >>/etc/inittab <<EOF #serial console login enabled co:2345:respawn:/sbin/agetty ttyS0 115200 vt100-nav EOF Changing the grub config to have hidden menu and other options like grub serial console had to be done in the post section also by sed. # modify grub for serial console sed -i -e 's/^timeout=5/serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 \ terminal --timeout=5 serial console \ timeout=5/' \ -e 's/^splashimage/#&/' /boot/grub/grub.conf Note that there is a bug in grub that prevents serial console output when the splashimage option is being used. _______________________________________________ Kickstart-list mailing list Kickstart-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/kickstart-list
