    I’m using Linux Mint 18.2 Sonya. My /etc/systemd/journald.conf has Storage=persistent set but when I run journalctl --list-boots I only ever get one entry, I’ve rebooted several times (and probably many times by the time you read this) but still no “persistency”.

    Any ideas?

    • Aaron Kili says:


      Run these commands to create a directory where your logs can be stored:

      # mkdir /var/log/journal
      # systemd-tmpfiles - -create - -prefix /var/log/journal
      # systemctl restart systemd-journald

        That seems to have fixed it. Thank you very much :-)

        I did some more research and discovered the documentation in /usr/share/doc/systemd/README.Debian says ‘If you enable persistent logging, consider uninstalling rsyslog or any other system-log-daemon, to avoid logging everything twice.”

        Should I uninstall?

        ‘rsyslog ‘sudo apt remove rsyslog‘ & ‘sudo apt purge rsyslog

        What about ‘other system-log-daemon’?

        • Aaron Kili says:


          If persistent storage is now working fine, I suggest you leave rsyslog installed. But if your system is now logging everything twice, then consider uninstalling it.

          • SmokinMoe says:

            How do I know if things are being logged twice?
            I guess two entries for every log item?
