25# DESCRIPTION:
26# 'zfs change-key' should correctly update encryption roots with clones.
27#
28# STRATEGY:
29# 1. Create an encrypted dataset
30# 2. Create an encryption root child of the first dataset
31# 3. Clone the child encryption root twice
32# 4. Add inheriting children to the encryption root and each of the clones
33# 5. Verify the encryption roots
34# 6. Have the child encryption root inherit from its parent
35# 7. Verify the encryption root for all datasets is now the parent dataset
