  21 # DESCRIPTION:
  22 #       Ensure that checkpoint verification within zdb wowrks as
  23 #       we expect.
  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. Verify zdb finds checkpoint when run on current state
  31 #       6. Verify zdb finds old dataset when run on checkpointed
  32 #          state
  33 #       7. Discard checkpoint
  34 #       8. Verify zdb does not find the checkpoint anymore in the
  35 #          current state.
  36 #       9. Verify that zdb cannot find the checkpointed state
  37 #          anymore when trying to open it for verification.

  43 # zdb does this thing where it imports the checkpointed state of the
  44 # pool under a new pool with a different name, alongside the pool
  45 # with the current state. The name of this temporary pool is the
  46 # name of the actual pool with the suffix below appended to it.
