+# DESCRIPTION:
+#	Ensure that checkpoint verification within zdb works as
+#	we expect.
+#
+# STRATEGY:
+#	1. Create pool
+#	2. Populate it
+#	3. Take checkpoint
+#	4. Modify data (include at least one destructive change) 
+#	5. Verify zdb finds checkpoint when run on current state
+#	6. Verify zdb finds old dataset when run on checkpointed
+#	   state
+#	7. Export pool, and verify the same things with zdb to
+#	   test the -e option.
+#	8. Import pool and discard checkpoint
+#	9. Verify zdb does not find the checkpoint anymore in the
+#	   current state.
+#	10.Verify that zdb cannot find the checkpointed state
+#	   anymore when trying to open it for verification.

+# zdb does this thing where it imports the checkpointed state of the
+# pool under a new pool with a different name, alongside the pool
+# with the current state. The name of this temporary pool is the
+# name of the actual pool with the suffix below appended to it.
