  # To add new config changes to NixOS:
  # - Dump current settings
  #     dconf dump / > dconf/$(date +%s).ini
  # - Change a setting, e.g. with dconf-editir
  # - Dump new settings
  #     dconf dump / > dconf/$(date +%s).ini
  # - Display changes
  #     diff --context=5 dconf/OLD-DATE.ini dconf/NEW-DATE.ini
  # - Add to `dconf.settings` below.

  # Restore settings:
  #   dconf load / < dconf/OLD-DATE.ini
