Issue description

Given this Home Manager config:

{ config, pkgs, ... }:

let
  homeDirectory = "/Users/jwork";
in
# https://nix-community.github.io/home-manager/options.html
{
  home.username = "jamie";
  home.homeDirectory = homeDirectory;

  # https://search.nixos.org/packages?channel=unstable
  home.packages = [
    pkgs.dnsmasq
  ];
  services.dnsmasq = {
    enable = false;
  };
  home.stateVersion = "22.05";
  programs.home-manager.enable = true;
}

... It says that services.dnsmasq does not exist, despite my having seen it used by other people on NixOS:

NixOS/nixpkgs#104181
NixOS/nixpkgs#27504
NixOS/nixpkgs#20863

➜  ~ home-manager switch
error: The option `services.dnsmasq' does not exist. Definition values:
       - In `/Users/jwork/Documents/git/nixpkgs/home.nix':
           {
             dnsmasq = {
               enable = false;
             };
           }

Am I misunderstanding something about home-manager? How should I configure dnsmasq through home-manager if not this?

Am I misunderstanding something about home-manager?

home-manager is designed for configuring user environments and not system services like dnsmasq.

... It says that services.dnsmasq does not exist, despite my having seen it used by other people on NixOS:
NixOS/nixpkgs#104181
NixOS/nixpkgs#27504
NixOS/nixpkgs#20863

These are NixOS system configurations and not home-manager configurations.

How should I configure dnsmasq through home-manager if not this?

It should be possible for you to configure dnsmasq through nix-darwin on macOS.

Indeed, as @anubhavkini said. It is not possible to configure dnsmasq or other system level services through Home Manager.
