+Rolling reboots with non-redundant instances
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, hroller plans capacity to move the non-redundant instances
+out of the nodes to be rebooted. If requested, apropriate locations for
+the non-redundant instances can be shown. The assumption is that instances
+are moved back to their original node after each reboot; these back moves
+are not part of the output.
