Hi,

I want to know briefly (for security reasons) what proprietary 
packages/programmes are on my laptop installed or run.

I unset IME (Intel Management Engine)

So my bootloader ist
/boot/efi and grub
/boot/efi/Guix/grubx64.efi

What is the difference of Grub, EFI, Shepherd, gnu-boot?

I assume gnu-boot is not for Guix.

In the manual I read Guix starts immediately with Linux libre kernel.

Could somebody briefly describe where are proprietary packages hidden in 
those running/initialising services?

thanks

Gottfried
