Static GRUB config migration completed successfully
Finished bootloader-update.service - Update bootloader on boot.
Arg, this is not resolved yet. It looks like the GRUB config is stored in the ESP instead of /boot/grub2 and thus we don’t update it as part of the migration. It notably does not include the part that enables BLS configs.
I’ve installed a “fresh” Silverblue 33, updated it to F42 and only got part of this issue and this did not prevent me from updating further so this is weird.
