PS2, Line 3: 
Just some idea for another follow-up: What about adding a howto for actually building the image?

One possible way, especially for non-nix-os systems, is using a docker container:

~~~
docker run --rm -ti -v "${PWD}":/coreboot nixos/nix sh -c "coreboot/build-console.sh && cp output/iso/nixos.iso /coreboot"
~~~

Could be done in a more clean way with a docker-compose config, too.
