[CentOS] How can I stop the eject of the DVD after install?

I have created my own install DVD with a custom kickstart file and modified the isolinux.cfg file to allow the system to boot off of the hard disk as the default mode. It will also use my kickstart file if I select it.

Now I would like to make the system not eject the DVD after reboot. The machines I am installing on do not have a motorized tray that can automatically pull the DVD back in when a mount command is issued. You have to push the disk in manually. As these machines will be unattended that is not idea.

How can I prevent the installer from ejecting the DVD once the install is complete?

Thanks!
