# Test for commit of discarded blocks
|
||||
#
|
||||
# This tests committing a live snapshot where some of the blocks that
|
||||
# are present in the base image are discarded in the intermediate image.
|
||||
# This intends to check that these blocks are also discarded in the base
|
||||
# image after the commit.
