What tool do you people think would fit well with Colmena when deploying bare metal?

 (...) | evaluation warning: system.stateVersion is not set, defaulting to 25.05. Read why this matters on https://nixos.org/manual/nixos/stable/options.html#opt-system.stateVersion.

Oh my bad, I forgot --experimental-flake-eval, this is the log I get:

Is disko perhaps not compatible with colmena?

In reply to @ibizaman:matrix.org
Any tool should be compatible. I used nixos-anywhere successfully and heard about nixos-infect working too. I’ve got a flake template for the former https://github.com/ibizaman/skarabox if you want some inspiration.

In reply to@ibizaman:matrix.org
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;
  };
}

In reply to @jh-devv:matrix.org
Does this support iPXE?

In reply to @luna:bddvlpr.com

{
  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;
  };
}

This is the current configuration, btw.

In reply to @luna:bddvlpr.com
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.

In reply to @luna:bddvlpr.com
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?
