In reply to @matthewcroughan:defenestrate.it
Is anyone aware that you cannot add new devices to robotnix that aren't supported in upstream due to the logic in flavors/lineageos/default.nix only allowing usage of official lineage devices, without the ability to override this behavior?

My attempt for androidVersion 13 with the current robotnix that fails like above, is here:

{ config, pkgs, ... }:

{
  # Enable F-Droid and the F-Droid privileged extension
  apps.fdroid.enable = true;

  # Disable the LineageOS Updater
  source.dirs."packages/apps/Updater".enable = false;

  source.dirs."device/samsung/hlte-common".src = pkgs.fetchgit {
    rev = "9a1bf8f7b8ca7f6dccc6462b76bf712893bd9d39";
    url = "https://github.com/html6405/android_device_samsung_hlte-common.git";
    sha256 = "";
  };

  source.dirs."device/samsung/hlte".src = pkgs.fetchgit {
    rev = "1ac57aea5ecfe0ef06f24f931e978151a2307731";
    url = "https://github.com/html6405/android_device_samsung_hlte.git";
    sha256 = "";
  };

  source.dirs."kernel/samsung/msm8974".src = pkgs.fetchgit {
    rev = "79c36b7a4b30e1216d9b1d071359f3d4a681d0b2";
    url = "https://github.com/html6405/android_kernel_samsung_msm8974.git";
    sha256 = "";
  };

  source.dirs."hardware/samsung".src = pkgs.fetchgit {
    rev = "05133e22669d90b1b844974b243861a5d8138f51";
    url = "https://github.com/html6405/android_hardware_samsung.git";
    sha256 = "";
  };

  device = "hlte";
  flavor = "lineageos";
  androidVersion = 13;
}
