Its very easy to say "per volume", but its a lot harder to implement, as
is clear for the trash spec and from anyone trying to implement
per-volume objects. per volume dirs have sharing and permission issues,
not to mention the hell that you have to go through to map from a
pathname to the volume its on (considering things like symlinks, bind
mounts, etc).
