Hm, this was new to me. Skimming through , it is not clear what kind of files
should be included here. The example refers to additional configuration files -
me it looks like it is useful only for files that do not exist in any installed

From how I understand the scripts ('prepare_rootfs' is called before packages
installed), a <buildroot dir>/files/etc/banner initially copied into the rootfs
would be overwritten with base-files/files/etc/banner when base-files*.ipk is
installed at the image install step. With that, <buildroot dir>/files/etc/banner
should never make it into a firmware image.
(This is from looking at the include files only, did not test, could be wrong.)

Depends. Since this is nowhere specified, one could also argue the files in
<buildroot dir>/files/ are meant as fallback in case no other package is
As for overwriting files without forking LEDE - we do it as follows: we have a
super git repository that hosts LEDE.git as a submodule with minor changes on
of upstream. One of those changes is to have a soft-link from $TOPDIR/overlay to
../overlay where our custom modifications for packages' files are kept.
This allows us to easily follow LEDE development (since rebasing is trivial) and
keep custom modifications to packages in our super repository.
