Journald includes the capability of rotating log files regularly to avoid filling up the system with logs or making the logs unmanageably large. The file /etc/systemd/journald.conf is the configuration file used to specify how logs generated by Journald should be rotated.Rationale:By keeping the log files smaller and more manageable, a system administrator can easily archive these files to another system and spend less time looking through inordinately large log files.
