   * Note: the next part is optional but I recommend it. Warewulf by defaults deploys ''stateless'' (in memory) but I'd rather deploy ''statefull'' in which VNFS is written to disk. The advantage is that if the node crashed, it will reboot without the help of the **master**, and Linux typically survives crashes. Actually I like the ''golden image'' even better, customize a node, then create the image.
