Description of problem: Looks like grubby is not btrfs subvolume aware :P when one is mounted at /boot. Version-Release number of selected component (if applicable): grubby-8.40-51.fc34.x86_64 How reproducible: Always Steps to Reproduce: 1. grubby --add-kernel=/boot/vmlinuz-5.11.6-300.fc34.x86_64 --copy-default --initrd=/boot/initramfs-5.11.6-300.fc34.x86_64.img --title=5.11.6TESTER 2. 3. Actual results: title 5.11.6TESTER version 5.11.6-300.fc34.x86_64 linux /vmlinuz-5.11.6-300.fc34.x86_64 initrd /initramfs-5.11.6-300.fc34.x86_64.img options root=UUID=32291cea-4dee-4e0d-bdf3-813314e2ab10 ro rootflags=subvol=root34 id fedora-20210312041911-5.11.6-300.fc34.x86_64 grub_users $grub_users grub_arg --unrestricted grub_class kernel Expected results: title 5.11.6TESTER version 5.11.6-300.fc34.x86_64 linux /boot/vmlinuz-5.11.6-300.fc34.x86_64 initrd /boot/initramfs-5.11.6-300.fc34.x86_64.img options root=UUID=32291cea-4dee-4e0d-bdf3-813314e2ab10 ro rootflags=subvol=root34 id fedora-20210312041911-5.11.6-300.fc34.x86_64 grub_users $grub_users grub_arg --unrestricted grub_class kernel Additional info: Easy work around, just edit the BLS and add /boot/ prefix, or whatever the name of the subvolume is, as reported by /proc/mounts as subvol= for the /boot line.
Variation of this found in bug 1953828. In that case the --args/--remove-args commands fail when --update-kernel=/boot/vmlinuz... rather than --update-kernel=/boot/boot/vmlinuz... but somehow --set-default= is not affected, nor is -update-kernel=ALL
