While I haven't done even an eyeball check recently, not too long ago the size savings for an aggressively pruned kernel could be quite noticable; there was also anecdotal support (waves hand) forfaster performance. Barring that? Every part of the kernel is something that can possbily go wrong, either by itself or by interacting with another part; if it isn't there, it can't break. Now the record on this really pretty awesome ... on the other hand, I can't argue with the person who doesn't want to roll those dice. And compile times of current generation hardware are pretty short. On an AMD Phenom II x4 940 (3 ghz) it's 5 minutes, maybe less. Robert Huff
