I've noticed disk checks on a colleagues system many times and will ask why on Monday and advise that whilst OpenBSD is rock solid it should still be shutdown gracefully.
I am sure this has already been considered but I shall ask anyway just in case. Despite running RO root systems in some cases I am now wondering if a Cron job to update the random boot seed every ? minutes might be a good idea to limit the chance of random boot seed re-use?
