Hi Zhaofeng Li !

I beleive colmena eval was only ever made to be impure (so the --impure option might be a mistake), see builtins.currentSystem in:

    introspect = f:
      f {
        lib = nixpkgs.lib // builtins;
        pkgs = nixpkgs.legacyPackages.${builtins.currentSystem};
        nodes = l.mapAttrs (evalNode {_module.check = false;}) comb;
      };

Ah, it's in your make-honey.nix, missed it. But the options should be passed correctly and there is no --impure:

$ colmena eval -E '{...}: builtins.currentSystem'
warning: Git tree '/home/zhaofeng/Git/fleet' is dirty
[INFO ] Using flake: git+file:///home/zhaofeng/Git/fleet?dir=nix
error: attribute 'currentSystem' missing

Zhaofeng Li: re https://github.com/NixOS/nix/pull/6530#issuecomment-1288195277

I wonder if there is a possibility to leverage the nix bundler interface instead of making a synthetic wrapper-flake...

But I haven't really dug deep on this, just planning to do this for styx...

There isn't a username in ssh-ng://your_ip, did you set deployment.targetUser to null? If so, then the default user it connects as (same as your username if you didn't configure anything) isn't trusted by the Nix daemon
