… to make sure it doesn't fail. It also introduce StartWithError, StopWithError and RestartWithError in case we care about the error (and want the error to happen). This removes the need to check for error and make the intent more clear : I want a deamon with busybox loaded on it — if an error occur it should fail the test, but it's not the test code that has the responsability to check that.
