I'm afraid this can't be put into practice. (User says which hardware and protocols he needs to be supported, scripts magically assemble a suitable configuration.) I think - sensibly modularize our software, - tell the user which software components there are, - what they are for, - how they depend on each other, - make it easy enough for the user to navigate in the dependency graph, - provide fundamental safeguards and checks for a proper software configuration is the best we can do. -- Stefan Richter -=====-==--- ---= --==- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
