Comment 4 for bug 1488009

Looks like this showmenu is working like this:

First, showmwnu=yes is hardcoded in the boot loader config isolinux/isolinux.cfg and EFI/BOOT/BOOTX64.conf

When kernel is booted showmenu is being written to /root/.showfuelmenu by the ks script. If there is no showmenu in the cmdline it defaults to "no".

Later when bootstrap_admin_node.sh is being run it sources /root/.showfuelmenu and if showmwnu="yes" Fuel menu is run.

So if you don't want to see this menu, as you most likely do, you can:

1) Just sent showmenu to "no" or remove it from cmdline by pressing TAB during the boot loaded phase.

2) Or you can shomehow replace solinux/isolinux.cfg on the iso with the same one but without showmenu hardcoded.

3) Or you can remove /root/.showfuelmenu file after the ks script have finished but before the bootstrap_admin_node.sh by sshing to the running installer.

I guess 2) is the best way if you want to automate the installer. You can even make iso building script accept the parameter that will controll showmenu variable in solinux/isolinux.cfg
