Yes, seems nice. Basically a union mount on the block layer. There are
some issues tho:
What do you do if the lower layer gets modified?
- while running
- while not running
We don't have a generic block device layering interface yet. I'd like
to have something like this before, then supporting cloop for instance
would be nice as well. I know some people don't like the
implementation of GEOM, but I think the basic principle is needed
anyways. Some kind of generic layering abstraction for block devices.
