# DESCRIPTION:
#	Verify '-o compatibility' property is updated in both the
#	pool config MOS object and the cache file.
#
# STRATEGY:
#	1. Create a pool with '-o compatibility=legacy', then verify
#	   the property exists in the MOS config and cache file.
#	2. Create a pool, set the 'compatibility=off' property, then
#	   verify the property exists in the MOS config and cache file.
