# DESCRIPTION:
# 'zpool set' should be able to enable features on pools
#
# STRATEGY:
# 1. Create a pool with all features disabled
# 2. Verify 'zpool set' is able to enable a single feature
# 3. Create a pool with all features enabled
# 4. Verify 'zpool set' is *not* able to disable a single feature
# 5. Rinse and repeat for known features
