So that I have tried:

      laptop = {
        deployment = {
          allowLocalDeployment = true;
          tags = ["laptop"];
          targetUser = "isaac";
          targetHost = "10.0.0.22";
        };

        imports = [
          ./nixos/laptop
          home-manager.nixosModules.home-manager
          {
            home-manager = {
              extraSpecialArgs = {
                inherit user;
              };
              useGlobalPkgs = true;
              users.${user} = {
                imports = [(import ./nixos/laptop/home-manager.nix)];
              };
              useUserPackages = true;
            };
          }
        ];
      };

But I get this:

For some reason there is an increasing number of people asking for support who use colmena.

And it is quite common that one wants to build the machine that causes issues to inspect the system closure.

For something like that it seems as if colmena build is quite practical, though at the same time it seems as if it lacks an argument to specify a single host to build. Is this indeed missing or did I miss something in the docs?

Also, it would be nice if there were appropriately named out links after a build.
