 The Buildroot developers recommandation is to start with the *Dynamic
 using devtmpfs only* solution, until you have the need for userspace
 to be notified when devices are added/removed, or if firmwares are
 needed, in which case *Dynamic using mdev* is usually a good solution.

+be performed by the +udev+ program provided by +systemd+.
