# DESCRIPTION:
# 'zfs inherit' should return an error when attempting to inherit
# properties which are not inheritable.
#
# STRATEGY:
# 1. Create an array of properties which cannot be inherited
# 2. For each property in the array, execute 'zfs inherit'
# 3. Verify an error is returned.
#

# Define uninherited properties and their short name.
