Description of problem:
Following http://www.krishnaraman.net/multi-node-openshift-origin-from-scratch/ to setup Multi-node OpenShift Origin PaaS from scratch.

After multi-node env is setup, broker and node machine can not be rebooted, once reboot, the multi-node env is broken.
for broker, after reboot, named can not be started up due to /var/named/forwarders.conf syntax error, looks like forwarders.conf is restored after reboot.

and /etc/resolve.conf will be re-writen by dhclient.

From now on, user must re-run ss-setup-broker, ss-setup-node and ss-register-dns commands.

We need figure out a method to make these configuration persistent.

BTW, in the instruction, 
3. Restart the node environment so that it can start services

If user follow this, due to /etc/resolve.conf is re-writen, that will cause mcolective connection is broken.
