Ooookay, after much gnashing of teeth investigating different environments and such, it looks like my change implicitly relies on some improvements to debuginfo package generation that are in rpm 4.20 or newer (Fedora 41 or newer), which is why I have not seen any issues up until this point. I am not entirely sure why yet though but I wanted to provide a small update that I am still looking into this. I plan to send the main 7.0 Kbuild pull request then I should be able to focus more intently on this. Cheers, Nathan
