Depends on who you ask, but imo it boils down to this:
- Use one filesystem as backing store, usually ro.
- Have another filesystem on top for extra functionality, usually rw

Famous example is a rw-CDROM, where writes go to hard drive and
unchanged data is read from CDROM. But it makes sense for other
things as well.


Data expands to fill the space available for storage.
