What is a "legitimate patch?"

KPIs like kauth let a 3rd party product interpose itself into kernel processing at well defined spots without having to patch it. The only reason to "patch" the kernel is to fix a bug in a particular kernel version if Apple isn't willing to roll a fix into the next update (which happened in Tiger once most of the engineers were concentrating on Leopard).

But it's a fallback. Start by describing what you're trying to do and ask for a KPI to do it (via bugreporter.apple.com so that it gets tracked). Saying "I want a generic way to patch the kernel" doesn't make a lot of sense.
