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.
+Note that if +systemd+ is chosen as init system, /dev management will
+be performed by the +udev+ program provided by +systemd+.
