++ One man's gawk is another man's KDE. A solution that expresses all dependencies and handles them well is much more elegant than one that requires hard-coding a list of core dependencies that we just think are too complicated to work out. Of course, to really get to the point where we'd have no system set at all we'd need to somehow automate the dependency generation, since otherwise ebuild maintenance would be very painful. Considering that we can't even tell if a program will halt it is clearly impossible to guarantee a perfect set of runtime dependencies. Of course, you might be able to come up with something that is good enough - especially when combined with the ability to add them in manually. None of this completely solves the fundamental bootstrapping problem. However, a full set of dependency specifications would let you at least determine what the minimal bootstrap actually is. I see all of this as more of an aspirational goal - one that we shouldn't fret about not being able to achieve, or subject ourselves to tremendous pain to get a little closer to. However, we also shouldn't hold back when opportunities to take a step closer arise. Rich
