How to stop child cgroup caused by PAMName=

Hello,

I want a service which executes 'startFoo.sh' exactly like a user 'Foo' would experience it. This is my current approach:

[Service]
ExecStart=/usr/bin/startFoo.sh

User=Foo

PAMName=login

And it seems to work just fine. But I can't figure out how to stop this service and all of its childs in a clean way. According to the systemd.exec documentation this service will start a 'session scope' CGroup but it does not mention how to stop this when the service stops. So far I found this workaround:

I add a

ExecStop=/usr/bin/stopFoo.sh

to the main service which does that:

#!/bin/bash
systemctl stop $(systemctl status $(pidof <anyProcessNameInsideTheChildCGroup>) | grep user.*slice | grep -o session.*scope)

Is there a clean solution to accomplish something like this?

Thanks and Kind Regards,
