# 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.
