Improvements to systemd service files

Current Situation

• When executing service files systemd frequently reports the following problems:

  • Can't open PID file /home/sos/install/agent/agent_4225/logs/agent.pid (yet?) after start: No such file or directory
    

• • • This warning is similarly reported for Controller and JOC Cockpit.
    • This warning is due to the fact that system checks too quickly for existence of a PID file.

  • /etc/systemd/system/js_agent_4445.service:13: Standard output type syslog+console is obsolete, automatically updating to journal+console. Please update your unit file, and consider removing the setting altogether.
    

• • • This warning is due to use of the syslog+console value for the StandardOutput and StandardError settings in systemd service files.
    • Since version systemd/246-2 in 2020 use of syslog is deprecated.

Desired Behavior

• systemd service files for Controller, Agent and JOC Cockpit should include in the [Service] section the settings:

  • ExecStartPost=/bin/sleep 1
    

  • StandardOutput=journal+console
    StandardError=journal+console
