  36 # DESCRIPTION:
  37 # An archive of a zfs dataset and an archive of its snapshot
  38 # changed sinced the snapshot was taken.
  39 #
  40 # STRATEGY:
  41 # 1) Create some files in a ZFS dataset
  42 # 2) Create a tarball of the dataset
  43 # 3) Create a snapshot of the dataset
  44 # 4) Remove all the files in the original dataset
  45 # 5) Create a tarball of the snapshot
  46 # 6) Extract each tarball and compare directory structures
