There is oe-pkgdata-util which can help to map files to recipes but we 
do not have a database for mapping. Maybe it is a good thing to have

for your problem ubiattach is provided by mtd-utils-ubifs which is built 
from mtd-utils recipe. I found it via above tool

% oe-pkgdata-util find-path /usr/sbin/ubiattach.mtd-utils
mtd-utils-ubifs: /usr/sbin/ubiattach.mtd-utils

% oe-pkgdata-util lookup-recipe mtd-utils-ubifs
mtd-utils

So you need to add

IMAGE_INSTALL_append = " mtd-utils-ubifs" in your image recipe or local.conf

If I were to pursue this method, any suggestions on how to separate the python3 files from the rest of my rootfs, including the necessary dependencies?
