+# 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.
