The post extract hook point is not really correct as what RTAI and Xenomai extensions are doing is patching the kernel. The post patch hook point doesn't work, because RTAI and Xenomai patches would be applied *after* all other patches, while it sounds more logical to apply them first, and *then* allow the user to apply some platform/board specific patches if needed.
