[Fedora-packaging] Removing files with RPM's build using python distutils

Hi, I am currently experimenting with packaging python projects using the distutils library. The packaging itself works fine, but I am having problems removing outdated/removed files when incrementing the RPM release counter or the version number. I thought that would be the RPM way :( Could someone explain me how to remove files using an rpm package in general, as I don't find anything related on the fedora packaging wiki pages? Example project structure: project-root -package1 --file1 -package2 --file1 --file2 Now packaging the project-root with both python packages works fine. When removing the file2 from package2, the file is no longer in the new resulting rpm with release=2 (0.1.1-2) or newer version (0.1.2-1), but updating the package on the destination server using yum update, does not remove the file. I suppose that I need to include a macro to remove files on the destination server.... As my current projects are all hosted on GIT repos, would there be an easier way to fulfill that task? Many thanks for some help on that point. Kind regards, Raoul
