No, not %{_libdir}, but rather %{_prefix}/lib. (i.e. we do not want to ship
two different versions for 32bit and 64bit. We want just one, hence they
belong in /lib unconditionally)
Best way to specify the path is %{_unitdir} however, which points to the
actual unit dir, and has been updated for the /usr merge already.
