  36 # DESCRIPTION:
  37 # to the originally snapshot'd file system, after the file
  38 # system has been changed. Uses 'sum -r'.
  39 #
  40 # STRATEGY:
  41 # 1) Create a file in the zfs dataset
  42 # 2) Sum the file for later comparison
  43 # 3) Create a snapshot of the dataset
  44 # 4) Append to the original file
  45 # 5) Verify both checksums match
