Use bind mounts or symlinks.

In systemd we think it's important that the same resources are
available under the same path as much as possible. Where that path
ultimately points to (by means of symlinks or bind mounts) doesn't
matter to us much, we just think it's much simpler if the paths stay
fixed and are useful universal identifiers, even if the stuff behind
them is actually placed somehere else.
