34# DESCRIPTION:
35# An archive of a zfs dataset and an archive of its snapshot
36# changed sinced the snapshot was taken.
37#
38# STRATEGY:
39# 1) Create some files in a ZFS dataset
40# 2) Create a tarball of the dataset
41# 3) Create a snapshot of the dataset
42# 4) Remove all the files in the original dataset
43# 5) Create a tarball of the snapshot
44# 6) Extract each tarball and compare directory structures
45#
46# TESTABILITY: explicit
47#
48# TEST_AUTOMATION_LEVEL: automated
49#
50# CODING_STATUS: COMPLETED (2005-07-04)
