Comment 3 for bug 1314887

Following up on my previous comment, the propose fix actually causes the upstart script to fail to start if there are no OVS interfaces present (the ifup errors which I believe causes the pre-start script section to "error" which then causes upstart to kill the process). I submitted a bit longer fix at https://code.launchpad.net/~brian-turek/ubuntu/trusty/openvswitch/fix-for-1314887/+merge/261912
