  This should work just fine. If you upgrade your F20 machine to say F22, it would have the default resolver running on with its entry in '/etc/resolv.conf'. One change you would need to do is to make it listen on or the on static IP address of your server. Your clients won't know that they are talking to a different DNS resolver.

If your clients are upgraded to F22, NetworkManager there would make the local resolver talk to the one on your server, because it'll receive that name server configuration via DHCP.

  Nope, we don't assume that. In fact it's been discussed earlier
