Yes: What they do is simply running the setup routine that also starts
after booting the cdrom and having done things like hardware detection
etc. They don't "boot" the cdrom but use it as a source for
bootstrapping the SuSE system.

They made it really easy for the user to set up a SuSE System in a DOMU
and I think they had to modify their setup system a little bit for this.
