Ideally, we should change to a system similar to what openSUSE does and have the RPMs install bootloader content into /usr, then execute a helper program that copies things over to /boot and configures things properly (we should still have the files %ghosted in /boot, though!). This makes it much more straightforward to support updating or downgrading bootloader files when needed, which is why openSUSE does it this way to support full system snapshots with rollback functionality. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
