Comment # 1 on bug 1167780 from Fabian Vogt

@snwint: As perl-Bootloader maintainer, would it be possible to have some
autodetection whether to update/install grub2/grub2-efi?

If not, I'll try to refactor the snippet in jeos-firstboot which adjusts
LOADER_TYPE on JeOS and shove it into a systemd firstboot service in a
subpackage.
