Overview

systemd-based boot scripts rely on the $network boot facility to express their dependency on the network status (note that '$' is the conventional way to refer to a boot facility and it does not imply variable substitution). According to the [Linux specifications], $network can be used to signal that basic network support is available. This definition is rather vague.
