Something like OBS (OpenSuse Build Service) would be useful for Mandriva

This would make packaging software much easier as you wouldn’t need to be intimately familiar with RPM specs or how it is configured for OM to build a package, provided that the software in question can be built using common build systems (autotools, cmake, etc.). The rest of packaging work could be easily automated, with packager only needing to provide some metadata such as software name, description, and the package name.

I understand that such service would be a huge undertaking, however I think the benefits such as increased software support would be worth it.

The backend will probably get attention before the frontend. I believe all of our mass build operations depend on someone to manually run them. When things like that are automated, then it makes sense to reduce the frontend complexity. Especially because update packages that have several dependents that also need to be rebuilt needs to be triggered or dependents will break.
