Comment:
Actually, we have the facility to enable EFI boot already with:

https://github.com/void-linux/void-packages/blob/master/srcpkgs/sbsigntool/template

But this one is only tested on booting directly from efi,
I'm running that one on my laptop, now.

The part to generate key and install it into UEFI is still missing, though.

I'm not grub's user, but I'm happy to take the work for it.
