# DESCRIPTION:
|
|
# to the originally snapshot'd file system, after the file
|
|
# system has been changed. Uses 'sum -r'.
|
|
#
|
|
# STRATEGY:
|
|
# 1) Create a file in the zfs dataset
|
|
# 2) Sum the file for later comparison
|
|
# 3) Create a snapshot of the dataset
|
|
# 4) Append to the original file
|
|
# 5) Verify both checksums match
|
