 Set ''rsync'' to work between the two. Unmount any NFS file systems on the node. Adjust the exclusion selections in template file (ie after /home is unmounted on node I do want the mount point...scratch space, etc).

 Yea.
+==== Deploying ====
+As part of my deployment I edited out any device information in file ''/etc/udev/rules.d/70-persistent-net.rules'', that information will be filled in on boot. Remade my VNFS. The reason for this is that in migrating from RHEL 5.5 to CentOS 6.7 I observed the order of the NICs to reverse themselves (but not always). Not sure why but will tell me what NIC eth0 will be.
+Then we build a template file with node specs in it like so:
+<code>
+# HP blades reverses HWADDR (don't ask)
+ # use nic port bottom (no changes)
+ # set both ipaddr/hwaddr then PXEboot, wait...ww times out but images
+ # post edit
+ #   /etc/udev/rules.d fix eth? entries per below, then startup scripts
+ #   eth0 down CC 10.10.x.x onboot=no
+ #   eth1 up   CD 192.168.x.x onboot=yes
+ # reboot (with bootload=EXIT)
+ n1  1C:C1:DE:1C:82:D5 192.168.102.10 1C:C1:DE:1C:82:D4 10.10.102.10 10.11.103.10
+ n2  1C:C1:DE:1C:81:01 192.168.102.11 1C:C1:DE:1C:81:00 10.10.102.11 10.11.103.11
