--- Comment #2 from Ondřej Kuzník ondra@mistotebe.net --- Ideally, we'd like to postpone startup until accesslog_db_root has finished but that is set up as a task and as such it needs to wait until startup. We'll have to schedule the purge task after we're open (and actually stop it when we're stopping the overlay) and not deal with operations that come in before the first time accesslog_db_root has run on an upgraded DB.
