Here is a sub-set of the option flow graph (that I can generate) out
of my configuration:

  boot.loader.generationsDir.enable -> system.boot.loader.id
  boot.loader.generationsDir.enable -> system.boot.loader.kernelFile
  boot.loader.generationsDir.enable -> system.build
  boot.loader.grub.configurationLimit -> system.build
  boot.loader.grub.configurationName -> system.build
  boot.loader.grub.copyKernels -> system.build
  boot.loader.grub.default -> system.build
  boot.loader.grub.device -> system.build
  boot.loader.grub.enable -> environment.systemPackages
  boot.loader.grub.enable -> system.boot.loader.id
  boot.loader.grub.enable -> system.boot.loader.kernelFile
  boot.loader.grub.enable -> system.build
  boot.loader.grub.extraConfig -> system.build
  boot.loader.grub.extraEntries -> system.build
  boot.loader.grub.extraEntriesBeforeNixOS -> system.build
  boot.loader.grub.extraPerEntryConfig -> system.build
  boot.loader.grub.splashImage -> system.build
  boot.loader.grub.timeout -> system.build
  boot.loader.grub.version -> boot.loader.grub.splashImage
  boot.loader.grub.version -> environment.systemPackages
  boot.loader.grub.version -> system.build
  boot.loader.initScript.enable -> system.build
