Non Switchable Systems
In certain systems, most notably image based appliances, updates are handled outside the system. This means that you do not need to rebuild your configuration on the system itself anymore.
If you want to build such a system, you can use the image-based-appliance
profile:
{ modulesPath, ... }:
{
imports = [ "${modulesPath}/profiles/image-based-appliance.nix" ];
}
The most notable deviation of this profile from a standard NixOS configuration
is that after building it, you cannot switch to the configuration anymore.
The profile sets config.system.switch.enable = false;, which excludes
switch-to-configuration, the central script called by nixos-rebuild, from
your system. Removing this script makes the image lighter and slightly more
secure.
