+	  "Lazy loading" defers loading file details until they are

+	  a bit longer.
+
+	  Lazy loading will only happen if enabled by this option being 'n'

+	  Wide tnodes are only used for large NAND arrays (>=32MB for

+	  slightly more RAM but are faster since they eliminate chunk group
+	  searching.
+
