The volatile-binds from meta-ro-rootfs can be used to handle exactly
this. (I.e. they doesn't have to point to tmpfs).
The 3rd alternative is the old classical approach of using a symbolic
links...

It depends on your which version you're running. Up to daisy, you'd have
to use meta-ro-rootfs to get access to volatile-binds.

Use volatile-binds.
