You don't need to manually make the overlay. You can either use colmena.overlays.default or take the package from colmena.packages.x86_64-linux.colmena directly. I do think it's worth it to have an example in the docs (which is busted right now) even though it follows the common flake pattern, another entry in the todo list

Another useful command is nix flake show github:zhaofengli/colmena which shows what a flake exports

gotcha. but im trying to run with the target laptop connected to ethernet (which i verified with ip a) and im still running into the error where

In reply to @zsuper:matrix.org
this does limit you to machines that are connected to the network via ethernet right? i was about to try this with an old laptop of mine, but i realized that nixos-anywhere does not support Wifi installation

In reply to @zsuper:matrix.org
and disko will still take care of formatting for you right? because thats the main part about minimal installers that im still uncomfortable with

im thinking of making the switch to colmena soon, but seeing the use of the function colmena.lib.mkHive worries me. will i still be able to access the raw nixosConfiguration closure in the flake's outputs?

the reason i ask is because nixos-anywhere reads nixosConfigurations.<name> when remote installing to a new machine, and id like to write the spec for each node/machine once in the flake and then have its NixOS configuration attribute set accessible

for example, with deploy-rs right now, i managed to write a helper function that allows me to define nodes like:

{
    deploy = {
      user = "root";
      sshUser = "root";
      nodes = self.armada.mkNodes {
        thinkpad = {
          hostname = "10.0.0.162";
          system = "x86_64-linux";
          modules = [
            ./modules/mc-server-host
            ./modules/cluster-server
            ./modules/starfish
          ];
        };
        t5 = {
          hostname = "10.0.0.249";
          system = "x86_64-linux";
          modules = [
            ./modules/cluster-agent
            ./modules/adguardhome
          ];
        };
        t4 = {
          hostname = "10.0.0.23";
          system = "x86_64-linux";
          modules = [
            ./modules/cluster-agent
          ];
        };
      };
    };

but this simply passes the inner arguments to lib.nixosSystem, which in turn gets passed to deploy.nodes.<name>.profiles.system.path. So this means I cannot access the "config" of thinkpad, for example
