From b87bdced1fa967846916b47cba5f093f72f3d11f Mon Sep 17 00:00:00 2001
From: Daniel J Walsh <dwalsh@redhat.com>
Date: Sun, 17 Feb 2019 21:55:30 -0500
Subject: Fix up handling of user defined network namespaces
If user specifies network namespace and the /etc/netns/XXX/resolv.conf
exists, we should use this rather then /etc/resolv.conf
Also fail cleaner if the user specifies an invalid Network Namespace.
