[opensuse-autoinstall] where are the pattern files?

Hi all, I want to install openSUSE Leap 42.1 via pattern list. But I can not find any pattern files in the installation repository (./suse/setup/descr/*.pat.gz) In openSUSE 13.1 pattern files exist but since openSUSE 13.2 they seem to be gone. In yast2 I can see patterns but what are their correct name to use them in a autoyast profile? Where are all the patterns defined now? Thanks in advance Regards Werner
