If you want to do scheduled hardware mainennance that's one thing. Doing hardware mainennance because something broke during software maintenance is something entirely different. If I schedule a reboot at 18:00 when hardly anyone's around, and the system fails because the hardware's suddenly broken, we're in trouble. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
