It might be useful to compress images during block-stream;
this way the user can merge compressed images of a backing chain and

I haven't looked at the patches yet so maybe the answer is obvious, but still:
would the "compress" option be still necessary if what we have is
blockdev-stream instead?


Sorry, I can't see blockdev-stream available now. How that would be
different? Would it imply the blocks are pulled up to the top (active)

Or did you mean block-commit? The option might be useful there as well,
and needs to be implemented separately
