# DESCRIPTION:
# 'zfs change-key -o' should change the keylocation.
#
# STRATEGY:
# 1. Create an encryption dataset with a file key location
# 2. Change the key location to 'prompt'
# 3. Verify the key location
# 4. Unmount the dataset and unload its key
# 5. Attempt to load the dataset's key
# 6. Attempt to change the key location to 'none'
# 7. Attempt to change the key location to an invalid value
#
