(and use the buildOnTarget option)

Or I push always all closures on a differnt build server.

Alright, next try to get this formatted correctly...

I recently updated to colmena 0.4.0 and cannot deploy from my Mac anymore:

~/.co/nixpkgs main ▷ nix develop -c colmena apply --on elara

The relevant parts from my flake.nix are:

      colmena = {
        meta = {
          specialArgs = { inherit inputs; };

          nixpkgs = import inputs.nixpkgs-stable { };
          nodeNixpkgs = {
            kerala = import inputs.nixpkgs-2305 { };

        };
        defaults = import ./nixos/remote-defaults;

        elara = { name, nodes, ... }: {
          deployment = {
            buildOnTarget = true;

            targetHost = "100.66.68.66";
          };

          imports = [ ./machines/elara.nix ];
        };

Any hints on what is going on here?

Hello folks; I just heard about Colmena today over at #nixops:nixos.org. I'm currently trying to evaluate whether its the right fit for my usecase (deploying a small number of VPS servers with the hopes of eventually scaling up).

What was the motivation of Colmena? I see its stateless, like Morph, which is a big plus for me. But what advantages does it have over Morph and NixOps?
