I am looking at the logs and the only network related log that coincides
with the resolv.conf file changing is:
<29> Arp 6 06:40:49 NetworkManager[542]:    ifcfg-rh:
updating /etc/sysconfig/network-scripts/ifcfg-eth0

at that point /etc/sysconfig/network-scripts/ifcfg-eth0 changes and gets
an NM_CONTROLLED="yes" added to it and the /etc/resolv.conf file is
replaced with the single lined one.
