Not transparently; mount(2) should _not_ mount two filesystems at once. Note that you'll run into serious problems as soon as you try to mount/umount/ mount --move the stuff there. And doing unionfs <spit> approach will cause fsckloads of fun issues with lifetimes. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
