Only security updates can be set to auto-install right now. And security is worth the risk of having to use K3B instead of Brasero for a week, isn't it? By the way, when was the last time an update (in a stable release) broke X? September 2006 is the last (and only!) one I remember. Ever since then, there's this horrible fear...come on, the lesson was learned, and kernels aren't being released until their accompanying modules are done building now. Shouldn't Jaunty's DKMS prevent issues with people who aren't using repository-sourced graphics drivers anyway? > Notice that you first have to solve the problem of the dpkg database > breaking, which actually happens and breaks the upgrade system, How common is that? And isn't it something that only happens if you manually kill -9 an apt process or if your hard drive is failing (which is expected to cause everything to break anyway)?

Not if you use that wonderful little setting in Software Sources so that it doesn't hold onto old packages until the end of time (and then some). As long as you let it auto-delete old debs, / shouldn't be filling up. Also, if you use the default Ubuntu install mode, /var, /tmp, and / will not be separate partitions. You'd need to fill the entire drive, at which point I wonder how you're getting anything done at all. > My best suggestion if you want e.g. your parents to use ubuntu without > risk when you are miles away from home, is to give them an USER account, > not an ADMINISTRATOR one, so they will not be bothered with upgrades > they don't understand.

Assuming you copy down the package list and changelogs on a piece of paper, right? -- Mackenzie Morgan http://ubuntulinuxtipstricks.blogspot.com apt-get moo
