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
