# 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.
