Thanks, this indeed improved things for the "netif" part of the problem.
But it still waited 30s for "default route interface". I found the
${defaultroute_delay} variable in /etc/rc.d/defaultroute, which isn't
documented, and set it to "1s" in /etc/rc.conf. This finally did the trick.

However, the networking on FreeBSD machines started to come up even longer.
I suspect this is because dhclient gradually increases the interval between
DHCP requests if it doesn't get an answer. I haven't found a way to
circumvent this. Any suggestions are welcome.
