You going to explain to me why "description something" shouldn't bring the interface up, but "inet autoconf" should? autoconf Set the AUTOCONF4 or AUTOCONF6 flag on the interface, depending on address_family. slaacd(8) automatically configures IPv6 addresses for interfaces with AUTOCONF6 set. dhclient(8) only configures interfaces with AUTOCONF4 set. The ifconfig man page says "inet autoconf" sets a flag. It does not say "sets the flag and brings the interface up". You want to argue against the documented behaviour? It is the dhclient *program*, activated by the "dhcp" word parsed by netstart, which brings the interface up, and operates unlike anything else in the system. What we want in the future when "autoconf" becomes the norm is hard to tell, but "inet6 autoconf" does not bring the interface up either.
