Not necessarily. Starting a daemon mounting a filesystem etc is significantly less CPU intensive both in duration and amount than starting a graphical user app. In fact for many the act of displaying the OK OK etc is more intensive than the actual startup. Note to that he's not saying everything in parallel, but rather those things that could be. It also allows a lot more latitude in playing with sequence. James > > eric
