25# DESCRIPTION:
26# 'zfs change-key' should promote an encrypted child to an encryption root.
27#
28# STRATEGY:
29# 1. Create an encrypted dataset
30# 2. Create an encrypted child dataset
31# 3. Create an unencrypted child dataset
32# 4. Attempt to change the key without any flags
33# 5. Attempt to change the key specifying keylocation
34# 6. Attempt to change the key specifying keyformat
35# 7. Verify the new encryption root can unload and load its key
36# 8. Recreate the child dataset
37# 9. Attempt to change the key specifying both the keylocation and keyformat
38# 10. Verify the new encryption root can unload and load its key
39# 11. Verify the unencrytped child is still accessible normally
