#
# DESCRIPTION:
#	Ensure that we can add a device while the pool has a
#	checkpoint but in the case of a rewind that device does
#	not show up.
#
# STRATEGY:
#	1. Create pool
#	2. Populate it
#	3. Take checkpoint
#	4. Add device and modify data
#	   (include at least one destructive change) 
#	5. Rewind to checkpoint
#	6. Verify that we rewinded successfully and check if the
#	   device shows up in the vdev list
