#
# ID: snapshot_007_pos
#
# DESCRIPTION:
# Verify that many snapshots can be made on a zfs dataset.
#
# STRATEGY:
# 1) Create a file in the zfs dataset
# 2) Create a snapshot of the dataset
# 3) Remove all the files from the original dataset
# 4) For each snapshot directory verify consistency
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
