Stateless Provisioning of Stateful Nodes: Examples with Warewulf 4

When deploying Warewulf 4, we often encounter expectations that Warewulf should support stateful provisioning. Typically these expectations are born from experience with another system (such as Foreman, XCAT, or even Warewulf 3) that supported writing a provisioned operating system to the local disk of each compute node.
