I have a fork of `justdoit.nix' https://github.com/cleverca22/nix-tests/blob/master/kexec/justdoit.nix https://github.com/cleverca22/nix-tests/blob/master/kexec/ju... which generates installer images with an auto-partitioning script and stub "configuration.nix" embedded in it with basically just enough of a system to get nixops or morph to deploy to it. it's kind of a pain to get that working the first few times since you have to wait for an image to bake and then test it in QEMU, and then make changes for nvme, etc, but it's brought up three systems now.
