| # Description: |
| # Verify that compressed streams can contain embedded blocks. |
| # |
| # Strategy: |
| # 1. Create a filesystem with compressible data and embedded blocks. |
| # 2. Verify the created streams can be received correctly. |
| # 3. Verify the presence / absence of embedded blocks in the compressed stream, |
| # as well as the receiving file system. |
