# DESCRIPTION:
# 'zfs rename' should not move an encrypted child dataset outside of its
# encryption root.
#
# STRATEGY:
# 1. Create two encryption roots, and a child and grandchild of the first
#    encryption root
# 2. Attempt to rename the grandchild under an unencrypted parent
# 3. Attempt to rename the grandchild under a different encrypted parent
# 4. Attempt to rename the grandchild under the current parent
# 5. Verify the encryption root of the dataset
# 6. Attempt to rename the grandchild to a child
# 7. Verify the encryption root of the dataset
