                          How am I supposed to do this in systemd?

    start unit.A
     started unit.A
    start unit.B
     started unit.B
    
    stop unit.A
     stopped unit.A
    stop unit.B
     stopped unit.B

---

I know After=/Before= will order units in reverse on start/stop like AB -> BA, but I need AB -> AB.

My guess is, that I have to merge unit.A with unit.B, something along the lines of

*unit.A.service:*

    ExecStartPost=unit.A

And handle stop ordering in ExecStopPost=.

**EDIT:**

It seemed that a combination of Upholds= and PropagatesStopTo= would probably give me what I want, or very close, but it turns out, those are added in systemd version 249, but I have to get it running on 241/247.

I still have an academic interest in whether Upholds= and PropagatesStopTo= would have been the right call, had I access to systemd 249?
