netstart is the command script that is
invoked by rc(8) during an automatic reboot and after single-user mode is

netstart script can also be used to
start newly created bridges or interfaces, or reset existing interfaces to
their default state. The behaviour of this script is (or can be) controlled

-n option reports the steps that
