21# DESCRIPTION:
22#	Ensure that we can rewind to a checkpointed state that was
23#	before a readonly-compatible feature was introduced.
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. Export pool
31#	6. Introduce a new feature in the pool which is unsupported
32#	   but readonly-compatible and increment its reference
33#	   number so it is marked active.
34#	7. Verify that the pool can't be opened writeable, but we
35#	   can rewind to the checkpoint (before the feature was
36#	   introduced) if we want to.
