On the second thought you still need to handle situation when B is already active when A gets started. Then you have no implicit dependencies at all (no socket activation happens), but A still depends on B during shutdown. So I'm afraid explicitly adding this information to A is the only way. > (however, I'm not sure it's achievable).
