There's no pending high-priority security updates, but it's been over 8 months since we've upgraded the kernel and rebooted. So I'll reboot at 3am (which is in 3.5 hours) P.S. Why the short notice? Cause I'm optimizing more for the scheduled time (Sunday wee hours) and my availability/motivation than advance notice. But let me know if that's a problem and I'll try harder for advance notice next time.
