# DESCRIPTION:
#   Verifying 'zfs receive -vn [<filesystem|snapshot>]
#          and zfs receive -vn -d <filesystem>'
#
# STRATEGY:
#   1. Fill in fs with some data
#   2. Create full and incremental send stream
#   3. run zfs receive with -v option
#   3. Dryrun zfs receive with -vn option
#   3. Dryrun zfs receive with -vn -d option
#   4. Verify receive output and result
#
