Dear Didier, I actually had the impression that servers was what Laurent was referring to... :) Anyway, it doesn't matter. Your clarification confirms my doubts: this quest for "speed" could make sense mainly for mobile devices (I personally reboot my laptop every 3/4 months, on average, and only because I forget to plug the AC adapter overnight, so I still can't see the issue for laptops), and I could agree on that, but please do not bring servers and high availability scenario to support "smart" dependency-based boots, since, as strange as it might sound, high availability has nothing to do with boot speed, at all.
