38#
39# DESCRIPTION:
40# to the originally snapshot'd file system, after the file
41# system has been changed. Uses 'sum -r'.
42#
43# STRATEGY:
44# 1) Create a file in the zfs dataset
45# 2) Sum the file for later comparison
46# 3) Create a snapshot of the dataset
47# 4) Append to the original file
48# 5) Verify both checksums match
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2005-07-04)
