### `crossDeploy` (optional, defaults to false)
Use this option if target host architecture is not the same as the build host
architecture as set by `buildHost` i.e. deploying to aarch64 from a x86_64
machine. Setting this option will disable building & running nix in the wrong
architecture when running `nixos-rebuild` on the deploying machine. It is
required to set `nixpkgs.localSystem.system` in the NixOS configuration to the
architecture of the target host. This option is only useful if the build host
also has remote builders that are capable of producing artifacts for the deploy
architecture.
