Configure WAN Interface Boot Delay
DHCP server responds within just a few milliseconds, but boot up hangs on configure WAN interface for 20+ seconds. The interface is active and responding to traffic during this time of delay with no firewall rules activated. Totally open system.
Same config on 2.3.3 i386 continues right on through without delay.

At least on my box, I've narrowed it down to the call to dhclient at source:src/etc/inc/interfaces.inc#L4281
Only suspicious thing in the dhclient error output is:
igb1: no link ...... got link
If I kill it and run it manually, it works immediately. Only at bootup does it appear to hesitate. From the message, I'd guess that the physical link isn't showing as up right away, but there is no related console message about the link coming up at the time, either.
