I have two questions so far regarding AutoYaST with SLES11-SP1 initrd:

1. is it possible to stop an installation when somebody interrupts the autoyast process by

pressing 'Abort' or similar things. We need to prevent users proceeding with manual installation

You could use the setupcmd boot option which specifies the exact yast start command. The default is setupcmd="setctsid `showconsole` inst_setup yast". You could append something like "; halt -f" to it to shut the machine down (for example) or add some script via dud or directly to the initrd to execute after yast. Note that yast talks via /etc/yast.inf to linuxrc. You might look there to decide if yast terminated normally or the user aborted.

2. how can I disable other tty's except the installation screen? I need to prevent console

logins at a second console. I didn't find /etc/inittab within the initrd of the installation medium.
