i expected declare machines as server1 = inputs.nixpkgs-2205.lib.nixosSystem { (...) to work

server1 = inputs.nixpkgs-2205.lib.nixosSystem { (...) }.config could also work, i think? But haven't tested this

In reply to @phaer:matrix.org
You don't need lib.nixosSystem for colmena, just the config

colmena = {
      meta = {
        nixpkgs = import nixpkgs { system = "x86_64-linux"; };
        specialArgs = { inherit inputs; };
      };
    } // builtins.mapAttrs (name: value: {
      nixpkgs.system = value.config.nixpkgs.system;
      imports = value._module.args.modules;
    }) (self.nixosConfigurations);

ok server1 = inputs.nixpkgs-2205.lib.nixosSystem { (...) } works locally with nixos-rebuild. This piece of code makes colmena overwrite nixpkgs-2205 for nixpkgs

In reply to @schnecfk:ruhr-uni-bochum.de
For that to work, you'll likely also need to use nodeNixpkgs as described in the colmena manual

How colmena would look like in a nushell:

colmena | where tag = oakland | each { |it| ^comena deploy ($it.fragment)  }

ok thanks
i haven't confirmed yet (and my rust-fu isn't good enough to tell simply by looking at the code) but there may be a tiny bug with deployments.keys.<name>.name when <name> and name don't match in the chown

feel free to ignore this so i'm forced to level up my rust game and verify+fix this myself
