To install smos on NixOS, a home-manager module has been provided as part of the smos repository's flake.

You can use it like this in your home.nix:

{ pkgs, lib, ... }:
with lib;
let
  smosModule = smos.homeManagerModules.${system}.default
in
{
  imports = [
    smosModule
    # [...]
  ];
  programs.smos = {
    enable = true;
  };
}

You can also declare your smos configuration using the programs.smos.config attribute. This will be translated to your configuration file and put into the right place automatically.

See also the reference documentation for this home manager module.

Optional: Using the cachix cache

If you use cachix, you can configure the smos.cachix.org cache as a public cache:

nix.binaryCaches = [
  "https://smos.cachix.org"
];
nix.binaryCachePublicKeys = [
  "smos.cachix.org-1:YOs/tLEliRoyhx7PnNw36cw2Zvbw5R0ASZaUlpUv+yM="
];

Server components

To install the server-side components of smos on NixOS, a NixOS module has been provided as part of the smos repository's flake.

{ pkgs, lib, ... }:
with lib;
let
  smosModule = smos.nixosModules.${system}.default
in
{
  imports = [
    smosModule
    # [...]
  ];
  services.smos.production = {
    enable = true;
  };
}
