Yes. It's a bit of a saga. Fedora takes an al la carte approach to the Boot Loader Spec, where we effectively have two $BOOT volumes. One for the bootloader and a forwarding configuration file, a second for the rest of the configuration files plus kernel and initramfs. Boot Loader Spec defines only one $BOOT where everything goes: bootloader, configs, kernel, initramfs. I suppose the main rationale for the approach we took is the path of least change. The main change was getting away from constant grub.cfg modification, and using drop-in configuration files that ostensibly any bootloader could support. But we didn't commit to the bigger changes: discovery by partition type code/UUID instead of filesystem UUID baked into a configuration file which has to be searched for by the bootloader; and the idea of putting kernel/initramfs on FAT was never popular. Possibly a big step toward better BLS compliance that also wouldn't be too controversial: * use XBOOTLDR partition type code for our ext4 /boot, and discover it by that type code rather than than by fs UUID * mount XBOOTLDR at /boot * mount EFI System at /efi But now I'm in the weeds, and it should be a different thread to discuss doing something different. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
