Hi Frank, you need to write a hook repository.OPENSUSE. Have a look at repository.CENTOS which might be a good example. This will make the repository of the opensuse packages available.
For installing package you just slightly modified files in package_config. But instead of PACKAGES install you can use PACKAGES zypper. install_packages -H shows all available names and the commands that are executed. If the package installation is working, you have to adjust the customization scripts to do the things an opensuse system needs. Hope this helps. Do not hesitate to also ask on irc. P.S.: The german comapny Tuxedo has a FAI based installer called WebFAI. It downloads the config space from https://webfai.tuxedocomputers.com/webfai-pc/fai_config.tgz which already includes config and scripts for SUSE. -- regards Thomas
