40# DESCRIPTION:
41#	'zfs recv -F' to force rollback.
42#
43# STRATEGY:
44#	1. Create pool and fs.
45#	2. Create some files in fs and take a snapshot1.
46#	3. Create another files in fs and take snapshot2.
47#	4. Create incremental stream from snapshot1 to snapshot2.
48#	5. fs rollback to snapshot1 and modify fs.
49#	6. Verify 'zfs recv -F' can force rollback.
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING_STATUS: COMPLETED (2006-07-18)
