# ID: zfs_promote_002_pos
#
# DESCRIPTION:
#	'zfs promote' can deal with multiple snapshots in the origin filesystem.
#
# STRATEGY:
#	1. Create multiple snapshots and a clone of the last snapshot
#	2. Promote the clone filesystem
#	3. Verify the promoted filesystem included all snapshots
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-05-16)
