In releases of nfs-utils upto and including 1.0.0, this option was the
-default. In this and future releases,
+default. In all subsequence releases,
.I sync
is the default, and
.I async
requested with
.IR subtree_check .
+From release 1.1.0 of nfs-utils onwards, the default will be
+.I no_subtree_check
+as subtree_checking tends to cause more problems than it is worth.
+If you genuinely require subtree checking, you should explicitly put
+that option in the
+.B exports
+file. If you put neither option,
+.I exportfs
+will warn you that the change is pending.
