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