I've also updated the autoyast file to work with any current version of openSUSE.

How far can I bend the rules? :-) E.g. would something like the following work? shell: 'find /usr/local/etc -name {{ item }} 2>/dev/null || find /etc -name {{ item }} 2>/dev/null'

Does the group require any specific properties? gid? System group?
