Can't you do the following (using /hurd as an example):
Without unionfs running on /hurd (which is a directory), you do
`ln -s /stow/hurd/hurd/unionfs /hurd/', so /hurd/unionfs is available
without unionfs running on /hurd.  Once unionfs is running on /hurd, its
old (i.e. the content of the directory `/hurd/') isn't visible anymore.

You'd also have to frob unionfs's executable then, since it most
probably depends on libc.so.0.3, etc., but doesn't have a RPATH for
/init/lib/.
