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