# DESCRIPTION:
# 'zfs load-key -L' should override keylocation with provided value.
#
# STRATEGY:
# 1. Create a key file
# 2. Copy the key file to another location
# 3. Create an encrypted dataset using the keyfile
# 4. Unmount the dataset and unload its key
# 5. Attempt to load the dataset specifying a keylocation of file
# 6. Verify the key is loaded
# 7. Verify the keylocation is the original key file
# 8. Unload the dataset's key
# 9. Attempt to load the dataset specifying a keylocation of prompt
# 10. Verify the key is loaded
# 11. Verify the keylocation is the original key file
