# DESCRIPTION:
# Test that receiving a full send as a clone works correctly.
#
# STRATEGY:
# 1. Create pool and filesystems.
# 2. Send filesystem, receive as clone of itself.
# 3. Verify that nop-write saves space.
# 4. Send filesystem, receive as clone of other filesystem.
# 5. Verify that contents are correct.
# 6. Repeat steps 4 and 5 with filesystems swapped.
