No, they would just be directories that could be used for overlays
(like in the case of sharing / with the parent, but overlaying a
different /var).

I think what Dan is suggesting is a way to automatically populate a
new var overlay when the user creates an "image" of the type
"directory" through libvirt.  They would say "create me a new var,
based on this other existing var over here".

BTW, I'd like to not have to implement this :-) It is just the conceptual model that would fit it with the storage API design...

:-) It would eliminate the need for mounts. Does it make more sense to integrate into the storage API design or leave the separate container specific mounts?
