[yocto] How do I create a recipe for laying down post-build config files?

[Maxim Radugin]

Hello Jim,

I don't think this is a good idea to put all the config files for different
packages in one recipe.
IMHO you should use .bbappend file for each recipe you are
overriding/modifying files for, otherwise you can run into situation when,
you recipe gets installed before, for example, grub.
Then your config will be overwritten by grub.cfg provided in grub package
(this is just an example, I'm not sure grub provides default one).

I wonder why you don't get another QA warning that you are overwriting
files that were installed by different package.

It is OK to put your specific files in such recipe, like RELEASE-NOTES.txt,
etc.

BR,
Maxim.
