The switch to BootLoaderSpec made switching boot loaders *much* easier. The actual boot loader config is fixed and never touched, kernel updates add/remove BLS config snippets, and all boot loaders handle that just fine. You can even have *two* bootloaders, sd-boot for efi mode and grub2 for bios mode. take care, Gerd _______________________________________________ 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, report it: https://pagure.io/fedora-infrastructure/new_issue
