RE: [opensuse-packaging] Patch RPM's and the -P option

The Red Hat/Fedora/rpm.org guides and the master RPM change list do not document a -P option. Can someone give me some background? Is this a SuSE creation? What distinguishes a patch RPM from a regular RPM?

Yes, it's a SUSE local change.

A patch RPM is really only a partial RPM, it can only be applied if the package is already installed.

Thanks, Andreas. How, then, do I develop a patch RPM? Are there spec file macros that tell rpmbuild that this is a patch? Sorry for all the questions. If you can steer me to relevant documentation, I'll go there. :-) -Scott
