-		whatever reason you invoke the command directly or, typically, pass <command>
-		as a single argument to spawn (eg. `spawn('balena', [ 'internal', 'sudo', 'ls -alF' ])`).
-
-		Furthermore, this command will naively split <command> on whitespace and directly
-		forward the parts as arguments to `sudo`, so be careful.
