+# DESCRIPTION:
+#	A pool should be importable using an outdated cachefile that is unaware
+#	that one or two top-level vdevs were added.
+#
+# STRATEGY:
+#	1. Create a pool with some devices and an alternate cachefile.
+#	2. Backup the cachefile.
+#	3. Add a device/mirror/raid to the pool.
+#	4. Export the pool.
+#	5. Verify that we can import the pool using the backed-up cachefile.
