  35 # DESCRIPTION:
  36 #       Verifying 'zfs receive [<filesystem|snapshot>] -d <filesystem>' works.
  37 #
  38 # STRATEGY:
  39 #       1. Fill in fs with some data
  40 #       2. Create full and incremental send stream
  41 #       3. Receive the send stream
  42 #       4. Verify the restoring results.
