FIXED RHEL 6 with Static IP Botching /etc/resolv.conf on Reboot

RHEL (6.4 and 6.5) Servers show their PC heritage when you assign server style static IP addresses instead of home network DHCP controlled IP networks. [[That will generate a few comments!!]]
I find the /etc/resolv.conf file gets modified after a reboot and so DNS fails - this is a broken as designed feature. I would enjoy someone trying to defend this feature and why it does this for my benefit! [[That will generate a even more comments!!]]
This is a quick blog entry for me to remember a combination that actually works for me. You might find it useful too.
Works = stops the reboot corrupting your /etc/resolv.conf file.
I could not claim I know why this combination works, as I have added and removed the NM_CONTROLLED and PEERDNS options a few times before they seems to start working by magic:
I have a brutal internal IBM firewall on the entrance to my computer room, so I have no problems sharing IP addresses :-)
