OS X offline DNS bug: no local DNS server when disconnected from networks

This video shows that as of OS X 10.10 (Yosemite) you can't use your machine for local web dev with a local DNS server with a wildcard to access your local sites when you are disconnected from a network

This is a real P.I.T.A. because you can't work on things when on planes/trains without Internet access unless you create a manual hosts entry, likewise it makes you look less professional when presenting things on premise at a clients.

I'm trying to work with Applecare on a resolution, but their not really groking it at the moment, and if it can't be resolved I'll be seriously considering a change of OS.

So the response from Apple is that is expected behavior, and the applecare contact suggested I use the hack proposed at http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-i... (which I sent to them)

At this stage he doesn't know if it will ever get fixed.. no indication from engineering..
