While we're on feature requests...

 - the same for things like netfilter etc..

 - the ability to generate permutation configs, I've had the need to
   build test code that had like way to many CONFIG options:

GROUP_SCHED * {USER_SCHED, CGROUP_SCHED} * FAIR_GROUP_SCHED * RT_GROUP_SCHED

   comes to mind. With a streamlined .config changing the configuration
   takes more time than actually building a bzImage.
