  35 # DESCRIPTION:
  36 #       'zfs recv -F' to force rollback.
  37 #
  38 # STRATEGY:
  39 #       1. Create pool and fs.
  40 #       2. Create some files in fs and take a snapshot1.
  41 #       3. Create another files in fs and take snapshot2.
  42 #       4. Create incremental stream from snapshot1 to snapshot2.
  43 #       5. fs rollback to snapshot1 and modify fs.
  44 #       6. Verify 'zfs recv -F' can force rollback.
