# DESCRIPTION:
#   verify that the snapshots created by 'snapshot -r' can be used for
#   zfs send/recv
#
# STRATEGY:
#   1. create a dataset tree and populate a filesystem
#   2. snapshot -r the dataset tree
#   3. select one snapshot used  for zfs send/recv
#   4. verify the data integrity after zfs send/recv
#
