Make it not fail if it can't find /etc/resolv.conf
Make it not fail if it can't find /etc/resolv.conf

On OSX /etc/resolv.conf is generated by the OS anytime the network
changes. If I create a network "By picking 'Create Network...'" from
the wifi menu then there is no /etc/resolv.conf and the throw
that was here would .. uh, .. throw.

Making it not throw makes the dns-server work for my purposes.
