+         If a filesystem does not explicitly specify a data ordering
+         mode, and the journal capability allowed it, ext3 used to
+         historically default to 'data=ordered'.
+
+         That was a rather unfortunate choice, because it leads to all
+         kinds of latency problems, and the 'data=writeback' mode is more
+         appropriate these days.
+
+         You should probably always answer 'n' here, and if you really
+         want to use 'data=ordered' mode, set it in the filesystem itself
+         with 'tune2fs -o journal_data_ordered'.
+
+         But if you really want to enable the legacy default, you can do
+         so by answering 'y' to this question.
