+----------------------

+*Thanks to Jordi Lino for this tip* .
+
+You can change the systemd configuration to limit the journal log disk usage (100 MB for example).
+Edit the /etc/systemd/journald.conf file and un-comment (remove # at the beginning) the line #SystemMaxUse= and change it to SystemMaxUse=100M.
