Comment 8 for bug 473036

OK, new plan after talking to Scott. Hardwiring device names into the initramfs means that if you ever swap network cards and forget to regenerate the initramfs then everything goes wrong. Instead, we'll add a facility to select network devices during initramfs network configuration by MAC address (and fall back to the previous behaviour if the MAC address selected that way doesn't exist). The network device might get renamed on entering the real system, but that's OK.
