The reason for having the "rootfs overlay" feature was simply to
factorize what a lot of people were doing in their post-build script:
copy a entire overlay of files to $(TARGET_DIR). Just like the
post-build script, it may not address *all* use-cases, but it certainly
address a good number of use cases.

I believe you can continue to use the rootfs overlay mechanism to copy
your files, and set use a custom permission table to adjust their
permission when the root filesystem image is created. It's probably
better than creating a complete package just for your files.

Thanks,

Thomas
