Quite!  If you need to force it to only start after some other unit has 
come up, a much more sensible approach would be to use "systemctl edit 
unbound.service" to create a drop-in unit (basically a local override) 
that adds an After= directive to the [Unit] section.  Or whatever else 
of that kind that you need.
