I'm not sure there is any legitimate case for booting $RELEASE1 and trying to have the installer install $RELEASE2. And even if there were, you can't do that now anyhow. It should be as simple as having apt- cdrom check lsb_release, and only look in that pool directory instead of searching them all.
