Subject: [PATCH] Automatically start systemd service if config file is present
 (#800)

Previously, upgrading the deb package stopped the service but didn't reenable it after a successful upgrade. This made upgrading the package more difficult and required a second step to restart the service. With this commit, the systemd service is automatically started when the default config file is present.
