Hi,
thanks for explaining this.

1.
I understood that
EFI is on the top
it runs Grub
and Grub runs the init system shepherd.

2.
Guix has a Grub without proprietary software AFAIU
and then remains the question about EFI.

3.
Can we exclude that EFI is without proprietary software?
Or has it only the task to run Grub?, because then it runs without 
proprietary software?

4.
Or are there other booting proprietary firmware blobs somewhere?
Or also Microcode updates?

5.
Do those things depend on the laptop or PC you have got?

I know Intel and ARM.
Risc-5 AFAIK has no proprietary software, is that right?
Or depends that on the company which produces Risc-5?

Thanks

Gottfried
