I believe that the Linux kernel configuration utilities you refer to are not RedHat specific (unless RedHat has decided to take it upon themselves to write a LOT of redundant code -- which would not surprise me in the least). The linux kernel source code has a menu-driven customization utility (both CLI and GUI) that comes with it. (If I'm wrong, someone correct me). Anyways, the Darwin kernel is not configurable in the manner that the linux kernel is. There is no GUI or command-line utility available for configuring xnu. xnu (so far as I'm aware) is pretty much "what-you-build-is-what-you-get". Why do you need to "tweak" your kernel in the first place? In linux, that's fairly understandable (though not so much with RedHat's kernel -- it's customized and has practically everything that everyone could want built in, or in module form -- or maybe that's *why* you want to tweak linux...*sigh*...linux...). Anyways, xnu is fairly straightforward -- what you see is what you've got. Hope this answers your questions (though I'm pretty sure it's not the answer you were *hoping* for).
