[bug#68524] Can uki be used with grub?

[amano.kenji]

I propose writing grub.cfg instead of modifying nvram.

1. Modifying nvram whenever there are changes to kernel images will increase 
wear and tear on nvram. If grub loads uki, then nvram lifespan will increase.

2. kernel arguments should go to both grub.cfg and uki because uki arguments 
are passed to kernel in the absence of secure boot. I'd like to be able to 
change kernel arguments in grub for debugging and troubleshooting.

Thus, the bootloader can be called grub-uefi-uki-bootloader and 
grub-uefi-uki-signed-bootloader.
