+	 * d0/d1/d2/f1 are all hardlinks to the same file; d0/l1 can't
+	 * be extracted with --strip-components=2 and the other two
+	 * can.  Remember that tar normally stores the first file with
+	 * a body and the other as hardlink entries to the first
+	 * appearance.  So the final result depends on the order in
+	 * which these three names get archived.  If d0/l1 is first,
+	 * none of the three can be restored.  If either of the longer
+	 * names are first, then the two longer ones can both be
+	 * restored.  Note that the "tar -cf" command above explicitly
+	 * lists d0/l1 before d0/d1.
+	 *
+	 * It may be worth extending this test to exercise other
+	 * archiving orders.
+	 *
+	 * Of course, this is all totally different for cpio and newc
+	 * formats because the hardlink management is different.
+	 * TODO: Rename this to test_strip_components_tar and create
+	 * parallel tests for cpio and newc formats.
