Customizing the openSUSE 11.0 instalation

I’m trying to create a instalation DVD with a personal RPM file that is marked to install by default in “normal” instalation process. The tutorial in Making a SUSE based distribution - openSUSE (it should be out of date) talk about *sel files where I could set packages to install by default but in folders creates by makeSUSEdvd -i -a /usr/src/packages/RPMS have no *sel files. I’ve found a makeSUSEdvd0–…pat file, but I have no ideia what I can do with this. I’ve found anything update about.

Any idea ?

Thanks a lot in advance.
