Additional info - I just booted from the 14.04.1 DVD and ifconfig looks a lot more like what I would expect - but networking ins't quite there yet on the DVD - probably just not correctly set up form LiveCD but only just discovered it so not sure. Also found that on the DVD I also see wireless.
eth0 is present but has no address - not terribly surprising I suppose, at least it is there.
