Trying to disable FirstBoot utility in LiveCD -> PXE image

Hello,

I am using RHEL6.2 and using livecd-creator followed by
livecd-iso-to-pxeboot

When the PXE boot image comes up it has what I believe is FirstBoot.

It says: "Text Mode Setup Utility"  and asks "Authentication
Configuration" "Keyboard Configuration" "RHN Register".  I just press
"Quit" and it continues fine to the login prompt.

In the kickstart file I have added the following line, but it does not
change the outcome for me:

firstboot --disable

Can anyone think of a good way to debug this?

I will paste the entire ks file below.

Cheers,
Ivan
