Can journald be told to start discarding the data (oldest or > latest) when it reaches the limit? Yeah, it's standard journald behaviour. By default journald will limit both the total disk usage, and will also not fill the fs above 90% (iirc). There were various issues with this logic in the past, but it seems to behave fairly robustly now. The idea is that journald does the "right thing" without any configuration or maintenance. The logic is suitable for normal fs layout, but if something different is needed, especially if you have a dedicated fs for log storage that can be filled to the brim, the limits and thresholds are all configurable (see http://www.freedesktop.org/software/systemd/man/journald.conf.html#SystemMaxUse= for available options).
