Well, according to previous answers, the 25 years old comment was actually justified, but if it weren't, style(9) would come to mind. Been eating your own dog food lately? If we understand that custom kernels are unsupported, that some kernel options can be modified without recompiling, and that some changes could have security implications, why do you care? Do you have to kill a kitten each time we build a custom kernel? Two if we actually tinker with the code? Maybe you should close the source, then.
