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