25# DESCRIPTION:
26# ZFS must promote clones of an encryption root.
27#
28# STRATEGY:
29# 1. Create an encrypted dataset
30# 2. Clone the encryption root
31# 3. Clone the clone
32# 4. Add children to each of these three datasets
33# 4. Verify the encryption root of all datasets is the origin
34# 5. Promote the clone of the clone
35# 6. Verify the encryption root of all datasets is still the origin
36# 7. Promote the dataset again, so it is now the encryption root
37# 8. Verify the encryption root of all datasets is the promoted dataset
