It would be useful if it were possible to make changes to the kernel configuration through the extensible SDK, so that devtool build-image would build a kernel with the changes applied. (We may be able to re-use existing tools we have for this.)
Do you have any more detailed thoughts about this? Would e.g. menuconfig and automatic config fragment generation on devtool update-recipe be enough?
I think that sounds ideal. Certainly a good enough to satisfy this feature request at least.
Patch sent for review: http://lists.openembedded.org/pipermail/openembedded-core/2016-February/117709.html After this patch, devtool now works on a single configuration fragment file, "devtool-fragment.cfg"
