Warning to those testing Rawhide on AArch64, grub2-2.02-23.fc28 will
fail on reboot. The package is already fixed in grub2-2.02-24.fc28,
to avoid any issues you can install directly from koji.
For those with f27-updates-candidate enabled in F27, grub2-2.02-21.fc27
is also broken and fixed with grub2-2.02-22.fc27.
If you already installed and your reboot fails, you can replace the
'grubaa64.efi' file on the system with the one from the updated
packages (found in grub2-efi-aa64).
