AutoYast script location

Hi, I'm preparing an installation DVD for SLES9 SP and want to use AutoYast with XML control file and customized shell scripts. Because I don't want copy the shell code into every XML control file I want it separately on the DVD. Is the following possible? <post-scripts config:type="list"> <script> <filename>post-install.sh</filename> <location>dvd:///autoyast/post-install.sh</location> </script> </post-scripts> Or does one need to write a wrapper script that mounts the DVD, copies and executes the script manually? How can this be done during chroot installation phase when the name of the CD/DVD device file is not known and the /dev/cdrom link does not yet exist? Regards, Bernd
