Re: No feedback from systemd / "systemctl stop X"... Nothing on stdout, nothing that `echo $?` can see...

This is on systemd's TODO list btw.:

http://cgit.freedesktop.org/systemd/systemd/tree/TODO
  - Add a verbose mode to "systemctl start" and friends that explains
    what is being done or not done

So the answer to the original question is: it's just not implemented
yet.

The verbosity notwithstanding, the exit code of 'systemctl start' does
reflect if something goes wrong:

# cat > /etc/systemd/system/demo-fail.service
[Service]
Type=oneshot
ExecStart=/bin/false
   (( press Ctrl+D here ))
# systemctl daemon-reload
# systemctl start demo-fail.service
Job for demo-fail.service failed. See 'systemctl status 
demo-fail.service' and 'journalctl -xn' for details.
# echo $?
1
# cat > /etc/systemd/system/demo-success.service
[Service]
Type=oneshot
ExecStart=/bin/true
   (( press Ctrl+D here ))
# systemctl daemon-reload
# systemctl start demo-success.service
# echo $?
0
# rm /etc/systemd/system/demo-success.service \
     /etc/systemd/system/demo-fail.service
# systemctl daemon-reload
