35# DESCRIPTION:
36#	When renaming a set of snapshots, if a snapshot already exists with
37#	the new name, then none of the snapshots is renamed.
38#
39# STRATEGY:
40#	1. Create a snapshot for a set of datasets.
41#	2. Create a new snapshot for one of datasets.
42#	3. Attempt to "zfs rename -r" with the second snapshot's name.
43#	4. Verify none of the snapshots is renamed.
