This also breaks ifconfig compatibility. An old ifconfig will not work with the new kernel and a new ifconfig will not work with the old. It is strongly recommended that you make a copy of your old ifconfig before installworld. If you are installing remotely, you must copy over a new ifconfig before rebooting in to the new kernel.
