Home manager module conflict

[blackxored]

It seems like we can't use the home manager module alongside the nixosModule, while this is most likely misconfiguration, I wonder if anyone's run into this?
error: The option `age.identityPaths' in `/nix/store/5mg8m013dk1dv3sl934ki6nbldgv23yf-source/modules/age-home.nix' is already declared in `/nix/store/5mg8m013dk1dv3sl934ki6nbldgv23yf-source/modules/age.nix

If this can help you I'm using both modules as I have system secrets and personal secrets.

What is do to avoid your error which I already encountered is this:

1. I load the nixosModule in my flake and pass the agenix input as extraSpecialArgs of my home-manager module like this :

          modules =
          [
            agenix.nixosModules.default
            home-manager.nixosModules.home-manager
            {
              home-manager = {
                useGlobalPkgs = true;
                useUserPackages = true;
                users.whateverUser = import ./config/home/home.nix;
                extraSpecialArgs = {
                  inherit unstablePkgs;
                  agenix = agenix;
                };
              };
            }
            .......

2. Then in my home.nix (or wherever you put this if you split your whole configuration) I import the homeManagerModules:

{ agenix, ... }:
{
  imports = [
    agenix.homeManagerModules.default
  ];

  age.identityPaths = [ "whereverIsMySecretsSSHKey" ];
  age.secrets = { Your secrets definition };
}

This works well on my setups. Maybe this is completely stupid and I would be happy to know the correct way of doing this, but including both modules on flake level ended up in the same issue you were presented.

Hope this helps.
