Yeah that is: https://systemd.io/COREDUMP_PACKAGE_METADATA/ https://fedoraproject.org/wiki/Changes/Package_information_on_ELF_objects There are actually patches to properly recognize those. https://sourceware.org/pipermail/elfutils-devel/2021q4/thread.html#4375 I'll integrate those asap. Cheers, Mark
