# DESCRIPTION:
# 'zfs change-key' should correctly update encryption roots with clones.
#
# STRATEGY:
# 1. Create an encrypted dataset
# 2. Create an encryption root child of the first dataset
# 3. Clone the child encryption root twice
# 4. Add inheriting children to the encryption root and each of the clones
# 5. Verify the encryption roots
# 6. Have the child encryption root inherit from its parent
# 7. Verify the encryption root for all datasets is now the parent dataset
#
