Nahh, you miss my point. I don't want my attention to be anywhere near the machine except for the 1 minute it takes to run the fetch, and then assuming that worked, for the 1 minute it takes to start the build. I then come back an hour or two later, make sure everything got done and I spent no time of my own fixated on a Gentoo box. Most of these machines get updated during the day when family is away, but I'm busy working here at home and don't want to pay much attention just to get updates done. I know others are way more involved with every little thing happening on their machines but I'm not. I run stable with a few ~amd64 packages. I just want to box to get updated and work without a lot of my time involved. I've done my wife's machine, my father's machine and my mother's machine this way for years and it doesn't take much effort. (It just works... (@tm) On my own 3 Gentoo machines I am a little more involved, but typically I'm working on them while updating so that's not such a bog deal. My attention is there. That said, maybe someone who hasn't touched the machine for 5 months shouldn't try to do a (mostly) unattended update... ;-) - Mark
