+.SS Subdirectory Exports
+
+Normally you should only export only the root of a filesystem. The NFS
+server will also allow you to export a subdirectory of a filesystem,
+however, this has drawbacks:
+
+First, it may be possible for a malicious user to access files on the
+filesystem outside of the exported subdirectory, by guessing filehandles
+for those other files. The only way to prevent this is by using the
+.IR no_subtree_check
+option, which can cause other problems.
+
+Second, export options may not be enforced in the way that you would
+expect. For example, the
+.IR security_label
+option will not work on subdirectory exports, and if nested subdirectory
+exports change the
+.IR security_label
+or
+.IR sec=
+options, NFSv4 clients will normally see only the options on the parent
+export. Also, where security options differ, a malicious client may use
+filehandle-guessing attacks to access the files from one subdirectory
+using the options from another.
