Vladimir told me once we are doing that because otherwise we would be
leaking too many "OS specific things" into the GRUB core and modules
which run on top firmware/bare metal instead of the OS. I hope he will
be able to tell us more here...

Anyway, I would be more than happy if we could find better way generating
configs for the GRUB.
