[lttng-dev] Trace rotation across sessions

Hello,

Our system has a running session that stays on continuously.

Occasionally, our customer will upgrade the software, leading to a reboot, 
which in turn means we will have a new session.

Is there any way to make LTTng aware of the total size of all sessions 
(current and past) and simply rotate files to keep the entire set of 
traces under a size limit?

Thanks,
