Ok I now have my test setup on a Virtualbox host with all of the same settings I was using on the physical machine and this time the update to trunk has no problems at all. I am able to PXE boot using my test machine.
It was not my intention to suggest that I will not be using Trunk or attempting to update to the latest and greatest. During this “test” I realized i could improve my methods a little. In the future I will be sure to report problems with my tests and try to work through them with the experts rather than just starting over off the bat.
I am going to test the functionality of my original posted question and I will report back.
