Hakurei is a tool for running sandboxed graphical applications as dedicated subordinate users on the Linux kernel.
It also implements [planterette (WIP)](cmd/planterette), a self-contained Android-like package manager with modern security features.

## NixOS Module usage

The NixOS module currently requires home-manager to configure subordinate users. Full module documentation can be found [here](options.md).

To use the module, import it into your configuration with

```nix
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";

    hakurei = {
      url = "git+https://git.gensokyo.uk/security/hakurei";

      # Optional but recommended to limit the size of your system closure.
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, hakurei, ... }:
  {
    nixosConfigurations.hakurei = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        hakurei.nixosModules.hakurei
      ];
    };
  };
}
```

This adds the `environment.hakurei` option:

```nix
{ pkgs, ... }:

{
  environment.hakurei = {
    enable = true;
    stateDir = "/var/lib/hakurei";
    users = {
      alice = 0;
      nixos = 10;
    };
