68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# Test that receiving a full send as a clone works correctly.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 1. Create pool and filesystems.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 2. Send filesystem, receive as clone of itself.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 3. Verify that nop-write saves space.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 4. Send filesystem, receive as clone of other filesystem.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 5. Verify that contents are correct.
68ecb2ec930c4b0f00acaf8e0abb2b19c4b8b76fPaul Dagnelie# 6. Repeat steps 4 and 5 with filesystems swapped.
