This looks like completely the wrong way to solve the copy+paste scriptlets problem. Turning a declarative configuration format into a programming language simply to eliminate common config is just nuts. If we want to eliminate the common scriptlets, then RPM should get richer metadata. By auto-generating the spec files from python you're just pushing the problem elsewhere & whenever the python wrapper needs to change the scriptlets you need to re-generate all the distro's spec files / RPMS. The vast majority of scriptlets can be eliminated if RPM knew what the file type is - eg, if it sees an ELF library, it should automatically run ldconfig. If it see a desktop file it should automatically run the desktop file install script, etc, etc. If done right you can add more scriptlets / change existing scriptlets for any existing RPM without needing to re-generate the RPM / spec.
