  None of these posts detail how to actually replace the kernel, only how to build it, nor what happens when Apple ships an update that changes the kernel.

    You install the kernel by running make install, then copying the stuff in BUILD/dst to /. (If you haven't changed any APIs accessible to kexts, you can get away with just copying mach_kernel.) When Apple ships an update, you compile the new kernel.
