The handling of a service with KillMode set to something other than cgroup

Hmm, could you test this with newer systemd please? 208 is already
quite old.
Where (in terms of: which cgroup?) does systemd-cgls show the left-over
processes?
In it's own cgroup, as would normally be the case:
│ ├─tester.service
│ │ └─24709 /home/ross/Downloads/tester start
We should show the cgroup contents regardless of the state of a
service actually, nothing should be hidden there. If things are hidden
just because of the service state then this would be a bug. If you can
reproduce it with 217 or so that would be great!
The same behavior seems to occur with 217 (on Arch):
# systemctl start tester.service
# systemctl status tester.service
● tester.service - Tester service
Loaded: loaded (/etc/systemd/system/tester.service; static)
Active: active (running) since Fri 2014-11-28 19:46:21 GMT; 4s ago
Main PID: 25067 (tester)
CGroup: /system.slice/tester.service
├─25067 /home/ross/Downloads/tester start
└─25068 /home/ross/Downloads/tester start
# systemctl stop tester
# systemctl status tester.service
● tester.service - Tester service
Loaded: loaded (/etc/systemd/system/tester.service; static)
Active: inactive (dead)
# ps aux | grep tester
root 25068 0.0 0.0 404876 ?S19:46 0:00
/home/ross/Downloads/tester start
# systemctl start tester.service
# systemctl status tester.service
● tester.service - Tester service
Loaded: loaded (/etc/systemd/system/tester.service; static)
Active: active (running) since Fri 2014-11-28 19:50:58 GMT; 2s ago
Main PID: 25148 (tester)
CGroup: /system.slice/tester.service
├─25068 /home/ross/Downloads/tester start -- the left over process!
├─25148 /home/ross/Downloads/tester start
└─25149 /home/ross/Downloads/tester start
With 217, running systemctl kill --kill-who=all -s KILL tester.service
doesn't fail, but it doesn't seem to do anything either.
Thanks,
