# DESCRIPTION:
# 'zfs load-key -r' should recursively load keys.
#
# STRATEGY:
# 1. Create an encrypted dataset
# 2. Create a child dataset as an encryption root
# 3. Unmount all datasets and unload their keys
# 4. Attempt to load all dataset keys
# 5. Verify each dataset has its key loaded
# 6. Attempt to mount each dataset
#
