Ok, it all makes sense. I agree, we should be pretty conservative about
what we're doing there.

Yup.

In the meantime, I'll rewrite the rest of the series to take this into
consideration. It's a few pretty trivial changes. Adding what I wanted
can very well be done later if Peter sees it fit to have.

The big remaining issue I can anyway work around outside Buildroot,
since in my case I do provide the Linux defconfig file, so I'm
prefectly OK with ditching this for now.

Thank you! :-)
