# Non Switchable Systems {#sec-non-switchable-system}
|
|
|
|
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:
|
|
|
|
```nix
|
|
{ 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.
