+Very similiar to writeDeploy, but just builds the system on the target without
+activating it.

+This basically makes the sources available on the target machine

+### `command`
+
+A function which takes the targetPath as an attribute.
+Example to activate/deactivate a swapfile before/after build:
+
+```nix
+pkgs.krops.writeCommand "deploy-with-swap" {
+ source = source;
+ target = "root@YOUR_IP_ADDRESS_OR_HOST_NAME_HERE";
