### Other Notable Changes {#sec-release-23.11-nixos-notable-changes}
- The new option `system.switch.enable` was added. It is enabled by default.
Disabling it makes the system unable to be reconfigured via `nixos-rebuild`.
This is of advantage for image based appliances where updates are handled
outside the image.
