21# DESCRIPTION:
22#	Ensure that checkpoint verification within zdb works as
23#	we expect.
24#
25# STRATEGY:
26#	1. Create pool
27#	2. Populate it
28#	3. Take checkpoint
29#	4. Modify data (include at least one destructive change)
30#	5. Verify zdb finds checkpoint when run on current state
31#	6. Verify zdb finds old dataset when run on checkpointed
32#	   state
33#	7. Export pool, and verify the same things with zdb to
34#	   test the -e option.
35#	8. Import pool and discard checkpoint
36#	9. Verify zdb does not find the checkpoint anymore in the
37#	   current state.
38#	10.Verify that zdb cannot find the checkpointed state
39#	   anymore when trying to open it for verification.

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