+We are going to take a shortcut when creating the resource this time though.
+Instead of explicitly saying we want the 'ocf:heartbeat:Filesystem' script, we
+are only going to ask for 'Filesystem'. We can do this because we know there is only
+one resource script named 'Filesystem' available to pacemaker, and that pcs is smart
+enough to fill in the 'ocf:heartbeat' portion for us correctly in the configuration.
+If there were multiple 'Filesystem' scripts from different ocf providers, we would need
+to specify the exact one we wanted to use.
+
Once again we will queue up our changes to a file and then push the
new configuration to the cluster as the final step.
