not to worry, only one person uses this system and i never do unattended upgrades (running testing or unstable at times). when i ran a production system there was a whole series of things needed to take the system down and up again. when people today complain that the system takes a few seconds longer to boot i mention that ours took 12hrs (or longer). songbird
