21# DESCRIPTION:
22#	Ensure that checkpoint plays well with indirect mappings
23#	and blocks.
24#
25# STRATEGY:
26#	1. Import pool that's slightly fragmented
27#	2. Introduce indirection by removing and re-adding devices
28#	3. Take checkpoint
29#	4. Apply a destructive action and do more random writes
30#	5. Run zdb on both current and checkpointed data and make
31#	   sure that zdb returns with no errors
