25# DESCRIPTION:
26# Unencrypted datasets should only allow keylocation of 'none', encryption
27# roots should only allow keylocation of 'prompt' and file URI, and encrypted
28# child datasets should not be able to change their keylocation.
29#
30# STRATEGY:
31# 1. Verify the key location of the default dataset is 'none'
32# 2. Attempt to change the key location of the default dataset
33# 3. Create an encrypted dataset using a key file
34# 4. Attempt to change the key location of the encrypted dataset to 'none',
35#    an invalid location, its current location, and 'prompt'
36# 5. Attempt to reload the encrypted dataset key using the new key location
37# 6. Create a encrypted child dataset
38# 7. Verify the key location of the child dataset is 'none'
39# 8. Attempt to change the key location of the child dataset
40# 9. Verify the key location of the child dataset has not changed
