# ID: zfs_receive_001_pos
#
# DESCRIPTION:
#	Verifying 'zfs receive [<filesystem|snapshot>] -d <filesystem>' works.
#
# STRATEGY:
#	1. Fill in fs with some data
#	2. Create full and incremental send stream 
#	3. Receive the send stream
#	4. Verify the restoring results.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-09-06)
