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.
