Talk: NixOS on ARM/Raspberry Pi

When trying to build a raspberrypi1 image i came across the section about "arm6 image works", however it is entirely unclear how to build or where to get this image. in nixpkgs there is nixos/modules/installer/sd-card/sd-image-raspberrypi.nix which should build a raspberrypi image like this: nix-build nixos -I nixos-config=nixos/modules/installer/sd-card/sd-image-raspberr ypi.nix -A config.system.build.sdImage. enabling arm6 cross-compiling, however is also a topic not further described in the nixos-on-arm super-page.
