  17 # DESCRIPTION
  18 # Verify zfs destroy test for clones with the livelist feature
  19 # enabled.
  20
  21 # STRATEGY
  22 # 1. One clone with an empty livelist
  23 #       - create the clone, check that livelist exists
  24 #       - delete the clone, check that livelist is eventually
  25 #         destroyed
  26 # 2. One clone with populated livelist
  27 #       - create the clone, check that livelist exists
  28 #       - write multiple files to the clone
  29 #       - delete the clone, check that livelist is eventually
  30 #         destroyed
  31 # 3. Multiple clones with empty livelists
  32 #       - same as 1. but with multiple clones
  33 # 4. Multiple clones with populated livelists
  34 #       - same as 2. but with multiple clones
