On Deployment, chatserver should be restarted

What is the current bug behavior?

When a new release is published, the chatserver still runs on the old release.

What is the expected correct behavior?

The chatserver should be restarted, so that the new code is applied.

Possible fixes

maybe set a flag file like chatserver_needs_restart and a cronjob running as root which checks for that file and calling systemctl restart fs-chatserver, in case of this file existing?
