Yeah, on non-NixOS hosts the Nix binaries aren't in the PATH set up by sshd/pam. It's a long-standing issue: https://github.com/NixOS/nix/issues/1078

Hi! I'm new to NixOS, but want to try out Colmena as a means to set up some computers in my home. One of them is a Microsoft Surface Pro 3, which needs <nixos-hardware/microsoft/surface-pro/3> to function properly. However, I'm struggling to use that with Colmena.

What I have now is something like this:

flake.nix
machines

• surface-configuration.nix
• surface-hardware-configuration.nix

In flake.nix:

inputs = { nixpkg.s.url = ... };

    deployment = { targetHost = name; targetUser="nixos"; };
    networking.hostName = name;
    imports = [
      <nixos-hardware/microsoft/surface-pro/3>
      ./machines/surface-configuration.nix
    ]
  };
};

And machines/surface-configuration.nix is the /etc/nixos/configuration.nix file copied from the surface after a fresh install. It, in turn, imports machines/surface-hardware-configuration.nix, which I've also left as default.

From this, I first get an error error: cannot look up '<nixos-hardware/microsoft/surface-pro/3>' in pure evaluation mode (use '--impure' to override), so I use --impure, but then get error: file 'nixos-hardware/microsoft/surface-pro/3' was not found in the Nix search path (add it using $NIX_PATH or -I. I should probably add it the proper way with a url to nixos-hardware as shown in the nixos-hardware section on flakes, but I'm not sure where to stick in those modules ref: (nixos-hardware#flakes)[https://github.com/NixOS/nixos-hardware#using-nix-flakes-support].

Does anyone know how I should proceed?

hit enter too soon... hold on

Done :)
