> I am using OE with my own overlay and I want to adjust linux kernel settings with minimal efforts. I have the following structure:

>      <others-includes>

> overlay/

> What I generally want is to simply replace defconfig with my own without changing recipe and touching other patches. I consider that having this structure could be fine for me:
> overlay/
>  recipes/
>    linux/
>      linux-davinci/
>        omapl137/
>          defconfig     (modified)

> I believe that changing FILESPATHBASE so that it will look in "recipes/linux/linux-davinci/omapl137" subfolder for each entry in BBPATH in defined order would solve my problem. For given example having FILESPATHBASE defines as "<topdir>/overlay/recipes/linux:<topdir>/oe/recipes/linux" would be enough.

Yes, that's correct, and is a common approach among those utilizing
collections/layers, but I don't believe it's in OE in any form.  A
.conf for the user/distro to include would likely be a bit cleaner
than a bbclass.
