[ckan-dev] Cannot kill ckan process

[Stefan Oderbolz]

This is actually a feature: if you kill a daemon ungracefully (i.e. using
kill -9 or the like), your system (e.g. systemd) detects that and
automatically restarts the daemon. So the clean way is to start/and stop
the services and not just kill the processes.
