That's right, so we have to provide a custom way. Which also is necessary for non root installs and for experimentation and trying out (your own) packages. Nevertheless I think in the long run it should not be a problem to integrate with: http://openbuildservice.org/ in order to also provide packages for distributions? Ideally the build systems configuration contains everything needed to automatically create a spec file for Fedora, for example.
