# ID: snapshot_006_pos
#
# DESCRIPTION:
# An archive of a zfs dataset and an archive of its snapshot
# changed sinced the snapshot was taken.
#
# STRATEGY:
# 1) Create some files in a ZFS dataset
# 2) Create a tarball of the dataset
# 3) Create a snapshot of the dataset
# 4) Remove all the files in the original dataset
# 5) Create a tarball of the snapshot
# 6) Extract each tarball and compare directory structures
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
