This tells NetworkManager to leave /etc/resolv.conf alone. Now you can put whatever you like in /etc/resolv.conf, and it will be left untouched.

I just found the answer after some more experimenting.

1. If you put some DNS information in any of your ifcfg-* interfaces, then NetworkManager will overwrite /etc/resolv.conf with whatever it find in there.

BUT...

2. If there is no DNS information in any of the ifcfg-* files, then NetworkManager will leave your manually edited /etc/resolv.conf configuration untouched. And this is the default behavior, no need to configure it specifically.

Problem solved. :o)

Thanks very much to everybody in this thread for your contribution.
