= Host-specific configuration
:toc:

These are NixOS configurations that are specific to a machine (e.g., desktop, servers, VM, containers).
Ideally, it should be made minimal as much as possible considering you also have to manage your users.




== Integrating with custom modules

The host configurations placed here most likely use the link:../modules/nixos[custom NixOS modules].
The custom modules shouldn't be imported manually from the host.
In the case for our link:../flake.nix[flake configuration], the importing of modules are already taken care of — specifically through `mkHost` from link:../lib/flake-utils[`../lib/flake-utils`] (see the linked file for the implementation).

It is best practice to assume the host configurations make use of the link:../modules/nixos[custom NixOS modules], link:../pkgs[custom packages], and the flake inputs.
In other words, always pay attention to link:../flake.nix[`../flake.nix`].




== User management

For managing users, there are multiple ways to manage them with this config:

* The usual `users.users.${user}` from system configuration (see `man configuration.nix.5`).

* If you intend to import users from the link:../users/nixos/[`../users/nixos/`], you can simply import them through `imports` in the system module.
+
For a convenient option, there is the function `getUsers` defined from the link:../lib[custom library].
You can use it as follows:
+
[source, nix]
----
imports = [ # Your modules ]
    # Import the following NixOS users.
    ++ (lib.attrValues (lib.getUsers "nixos" [ "foo-dogsquared" "polski" ]));
----

* link:../modules/nixos/profiles/users.nix[`modules.users.users.${user}`] which is my implementation for managing users from link:../users/home-manager/[`../users/home-manager/`] — e.g., `modules.users.users.foo-dogsquared = {}`.
This is integrating my home-manager users to map into NixOS users.
