Title: 6.7.8. Configuring Node Settings

Describe the issue:
The deployment guide lists this command to update ServerName in httpd:

sed -i -e "s/ServerName .*$/ServerName `hostname`/" \
 /etc/httpd/conf.d/000001_openshift_origin_node.conf

However, ServerName is no longer set in that file. It's set in:

/etc/httpd/conf.d/000001_openshift_origin_node_servername.conf

Suggestions for improvement:

Use sed on the openshift_origin_node_servername.conf instead of (or in addition to) the old one.

Additional information:

Using sed on the old file does update all of the 'ServerName' entries listed in that file, but those are commented out and not used by default.
