 +The owner of the list thread posted this solution for the UEFI problem. Look in the deploy script on how to handle that.  My work around was to deploy a 7.2 image using a Warewulf stand alone 3.6.99 installation, then update the node kernel. (building a 3.6.99 version [[cluster:139|Warewulf Stateless]]).
