There are two errors at the end there, setting root filesystem and grub stuff. Usually those come from running the hardware generator on the new machine and that gets you a hardware-configuration.nix file. You must include that file or recreate the options it is setting for the configuration to be happy.

{
  self,
  inputs,
  ...
}: let
  inherit (self) outputs;
  inherit (builtins) mapAttrs;
in {
  flake = {
    colmena =
      (mapAttrs (host: value: {
          deployment = {
            targetHost = "${host}.cloud.bddvlpr.com";
          };
        })
        outputs.nixosConfigurations)
      // {
        meta = {
          nixpkgs = import inputs.nixpkgs {
            system = "x86_64-linux";
            overlays = [];
          };
        };
      };

    colmenaHive = inputs.colmena.lib.makeHive outputs.colmena;
  };
}

Does this support iPXE?

    colmenaHive = inputs.colmena.lib.makeHive outputs.colmena;
  };
}

This is the current configuration, btw.

No, I think I get what I'm doing wrong now. I thought that it just required outputs.colmena to get the deployment settings and would actually look up the host at outputs.nixosConfigurations like deploy-rs would. I'll try just merging them now.

Can't it be dynamic depending on the host running commands?

In reply to @luna:bddvlpr.com
Another small note, can I define --experimental-flake-eval somewhere in the config that I don't have to add it to every command?

I think it’s this issue that has been fixed, but I think a new version of colmena including it hasn’t been released yet
