I'm seeing the same thing going from p6 to p8.

On boot;

  fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          inet 192.168.3.112 netmask 0xffffff00 broadcast 192.168.3.255
          ether 00:30:48:23:bc:42
          media: Ethernet autoselect (100baseTX <full-duplex>)
          status: active
  em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
          options=3<rxcsum,txcsum>
          inet 172.16.2.112 netmask 0xffffff00 broadcast 172.16.2.255
          ether 00:30:48:22:bc:41
          media: Ethernet autoselect (1000baseTX <full-duplex>)
          status: active
  add net default: gateway 172.16.2.1

Then log in from a host on the same network;

  > netstat -nr
  Routing tables

No default route. No error on the 'route add ...' in rc.network.

After boot;

  # route add default 172.16.2.1
  add net default: gateway 172.16.2.1
  # netstat -nr | fgrep default
  #

  # uname -a
  FreeBSD host 4.8-RELEASE-p8 FreeBSD 4.8-RELEASE-p8 #4:

Looks like this could bite a lot of people.
