Well, think about it - by that logic, if CONFIG_* items are an ABI, we will never ever be able to change any of them. Now that would be awful. > Any progress on this? We're thinking... We might need an official scheme of stating what any given kernel image supports for use by external tools which need it. > BTW: I see that this could help preventing problems like the current one > to happen in the far future.
