  21 # DESCRIPTION:
  22 #       Ensure that we can rewind to a checkpointed state that was
  23 #       before a readonly-compatible feature was introduced.
  24 #
  25 # STRATEGY:
  26 #       1. Create pool
  27 #       2. Populate it
  28 #       3. Take checkpoint
  29 #       4. Modify data (include at least one destructive change)
  30 #       5. Export pool
  31 #       6. Introduce a new feature in the pool which is unsupported
  32 #          but readonly-compatible and increment its reference
  33 #          number so it is marked active.
  34 #       7. Verify that the pool can't be opened writeable, but we
  35 #          can rewind to the checkpoint (before the feature was
  36 #          introduced) if we want to.
