Problems creating custom ISO file!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi again, Now i found out when the pakages have been copied to creat a custom iso-cd the mkiso command has a link to the boot/boot.catalog, but there is no boot.catalog in the directory boot (/tmp/YaST2-0815/iso_skeleton/skeleton/boot/...) ...or am i complete wrong?? Greetings marc
