39# DESCRIPTION:
40# An archive of a zfs file system and an archive of its snapshot
41# is identical even though the original file system has
42# changed sinced the snapshot was taken.
43#
44# STRATEGY:
45# 1) Create files in all of the zfs file systems
46# 2) Create a tarball of the file system
47# 3) Create a snapshot of the dataset
48# 4) Remove all the files in the original file system
49# 5) Create a tarball of the snapshot
50# 6) Extract each tarball and compare directory structures
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2005-07-04)
