6.5. Installing and Configuring MCollective on Node Hosts
Procedure 6.6. To Install and Configure MCollective on the Node Host:
Step 2

In keeping with how the broker mcollective client log has moved, the logfile line here should move under the node logs dir. So
logfile = /var/log/ruby193-mcollective.log
=>
logfile = /var/log/openshift/node/ruby193-mcollective.log


And in order to ensure that this log directory actually exists as well as the node agent mcollective refers to, this section should be moved into the next, 6.6. Configuring Node Host Packages -- right after the core packages, so it would become 6.6.1. It makes a little more sense to the flow anyway.
