  36 # DESCRIPTION:
  37 # Verify that many snapshots can be made on a zfs file system.
  38 #
  39 # STRATEGY:
  40 # 1) Create a files in the zfs file system
  41 # 2) Create a snapshot of the dataset
  42 # 3) Remove all the files from the original file system
  43 # 4) Verify consistency of each snapshot directory
