Minor whackery. Add "-r" option to node_reboot to "reconfig" a pnode
instead of rebooting. If the reconfig fails, fail through to reboot. A reconfig will "halt" the current vnodes (or remove ones that are no longer assigned to the node) reconfig the pnode, and then restart the vnodes that are still assigned to the node (or create new ones for newly assigned vnodes). A halt stops the vnode, but leaves the vnode filesystem intact. Not bothering to reconfig individual vnodes yet since thats pretty much like a reboot of a vnode. Difference in time is tiny. Lbs
