Variables

var FetchFile = func(src string) ([]byte, error) {
	var f []byte
	var err error

	if env.Config().GetBool("FetchFromRemote") {
		f, err = fetchFromRemote(src)
	} else {
		f, err = FetchFromLocal(src)
	}

	return f, err
}

FetchFile first tries to retrieve file from local disk (workDir/<Hostname>/). If it fails then connects to Hostname to retrieve file and stores it locally To force a network connection remove workDir/... prior to exec.
