From a7eb3476557dae28880333544c797705ee2f5b5a Mon Sep 17 00:00:00 2001
From: Dan Winship <danw@gnome.org>

Subject: [PATCH] ifcfg-rh: /etc/hostname should override
/etc/sysconfig/network
When determining the system hostname, /etc/hostname should override
/etc/sysconfig/network, so monitor both files.
When setting the hostname, set it in /etc/hostname, and delete the
/etc/sysconfig/network HOSTNAME entry if present.
