Do you have any idea what went wrong? I don't recall hearing of

else having this trouble, yet. And we've definitely had pre-BLS
installs upgraded, as people hit the GNOME login bug on them...
The current hypothesis is that the system was using and updating
/boot/grub2/grub.cfg, leaving /boot/efi/EFI/fedora/grub.cfg to go stale,
and the upgrade replaced the file in use with the stale one.
This would mean that different programs have different ideas about
which grub.cfg is in use.
