Since "Unify the GRUB configuration files" /boot/grub2 is the default directory.
But in uefi mode the fonts directory is in /boot/efi/EFI/fedora and missing in /boot/grub2.
So grub doesnt find /font/unicode.pf2 and cant boot in graphical mode.
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
