  36 # DESCRIPTION:
  37 #       'zfs promote' can promote a clone filesystem to no longer be dependent
  38 #       on its "origin" snapshot.
  39 #
  40 # STRATEGY:
  41 #       1. Create a snapshot and a clone of the snapshot
  42 #       2. Promote the clone filesystem
  43 #       3. Verify the promoted filesystem become independent
  44 #
