Commit62089b8048("kbuild: rpm-pkg: Generate debuginfo package manually") moved away from the built-in RPM machinery for generating -debuginfo packages to a more manual way to be compatible with module signing, as the built-in machinery strips the modules after the installation process, breaking the signatures. Unfortunately, prior to rpm 4.20.0, there is a bug where a custom %files directive is ignored for a -debuginfo subpackage [1], meaning builds using older versions of RPM (such as on RHEL9 or RHEL10) fail with: Checking for unpackaged file(s): /usr/lib/rpm/check-files .../rpmbuild/BUILDROOT/kernel-6.19.0_dirty-1.x86_64 error: Installed (but unpackaged) file(s) found: /debuginfo.list /usr/lib/debug/.build-id/09/748c214974bfba1522d434a7e0a02e2fd7f29b.debug /usr/lib/debug/.build-id/0b/b96dd9c7d3689d82e56d2e73b46f53103cc6c7.debug /usr/lib/debug/.build-id/0e/979a2f34967c7437fd30aabb41de1f0c8b6a66.debug ... To workaround this, restrict the manual debug info package creation process to when it is necessary (CONFIG_MODULE_SIG=y) and possible (when using RPM >= 4.20.0). A follow up change will restore the RPM debuginfo creation process using a separate internal flag to allow the package to be built in more situations, as RPM 4.20.0 is a fairly recent version and the built-in -debuginfo generation works fine when module signing is disabled.
