          # Example: Managing Home Manager through NixOS
          #
          # This approach allows you to manage user configurations (dotfiles) as part of the system generation.
          #
          # Benefits:
          # 1. Atomic Rollbacks: Reverting the system generation also reverts the home environment (dotfiles, packages).
          # 2. Sync: Ensures system and user configurations are always in sync.
