Hello List,
I am creating a diagnostic livecd that will run a custom script as
soon as it boots.
I'd like to bypass the login screen altogether and automatically log
in as the root user.
I was considering creating a custom rpm with the following lines in
the following files like so:
/etc/gdm/custom.conf AutomaticLoginEnable=true
AutomaticLogin=root
and my /etc/pam.d/gdm
#auth required pam_succeed_if.so user != root quiet
Is there a better way to achieve this than customizing these config
files and over-writing them in an RPM?
Thanks in advance.

One way people do stuff like this is in the %post section write commands to
a file that gets run when the live image boots up. You can probably do
what you want there. Then you would have a custom ks file instead of
a custom rpm.

Yes: 'sed -i' is your friend here.
If you install spin-kickstarts and then look
in /usr/share/spin-kickstarts/fedora-live-desktop.ks, you'll find some
examples.

Got it. sed in the post scripts to modify the config files.
So I did that with the following commands in my kickstart:
#enable root login
sed -i s/"auth required pam_succeed_if.so user != root
quiet"/"#auth required pam_succeed_if.so user != root quiet"/
/etc/pam.d/gdm
#enable automatic login as root
sed -i
s/"daemon]$"/"daemon]\nAutomaticLoginEnable=true\nAutomaticLogin=root"/
/etc/gdm/custom.conf
POC
For some reason it still displays the login screen.
If I type root and hit enter it goes into a shell prompt with no
problem. I'd like to have to avoid typing anything. It seems that
changing these commands in the post scripts is a bit late to get the
desired effect.

You might try booting with single on the kernel command line, this will
drop the system into a root shell. Some services will not be started.

The mingetty modification worked. Thank you to everyone on the list.
You all are a great help.
Just for reference here is how I modified my /etc/init/tty.conf to
bypass the login on a console-only machine:
sed -i s/"exec \/sbin\/mingetty $TTY"/"exec \/sbin\/mingetty
--autologin root $TTY"/ /etc/init/tty.conf
which gives you:
#tty.conf
stop on runlevel [016]
respawn
instance $TTY
exec /sbin/mingetty --autologin root $TTY

What can I do if I want to have only TTY1 automatically logging in as

the livecd has started up?

Hello list!
There are situations where you want to switch between different console
windows. With the automatic login recommendation that we got (se below),
we cannot switch console after the livecd has started. The
suggestion is as follow:
