for now I'm doing my local testing a little more manually, with some customized install media that mounts the repo containing my NixOS config using a VirtFS share and includes disko and nixos-anywhere on it

if I can figure it out, though, would moving disko to use pkgs.nixosTest instead of make-test-python.nix as its entrypoint for NixOS vm-tests, and then modifying nixos-anywhere.sh to support running that test locally when it is used on macOS hosts be an agreeable change?
