+- move post scripts into corresponding subpackages to ensure they are
+  run after updated binaries are installed. Currently it may happen
+  that update-bootlader picks up old binaries.
+- move requires for perl-Bootloader to target subpackages. Make sure
+  efi requires minimal version that supports /boot/grub2.
+- add requires(post) to force order of installation: grub2 => grub2-arch
+  => grub2-efi
+- split efi post in two parts. One that updates configuration and is part
+  of grub2-efiarch and second that migrates settings and is part of
+  grub2-efi. Only custom.cfg and grubenv may need migration. device.map
+  is not relevant for EFI and new grub.cfg had been created at this point.
