Executes in foreground, printing the events at console. Useful for testing it, and to be used by systemd or Unix System V respan. If not specified, the program runs in daemon mode.


Record RAS events via Sqlite3. The Sqlite3 database has the benefit of keeping a persistent record of the RAS events. This feature is used with the ras-mc-ctl utility. Note that rasdaemon may be compiled without this feature.
