Thanks Ludovic and Mark! I tried to follow your advices but eventually
I got the same error:
guix system: error: build failed: a `x86_64-linux' is required to build `/gnu/store/zh42mbm0wvbsz05zr798nchyd3bc7fh6-guix-0.8.2.c2ee19e.drv', but I am a `i686-linux'
I used the following command:
guix system init --no-grub config-64-simple.scm /mnt/guix
I'm attaching the OS config I used. Did I miss anything?
