While you cannot *enforce* a change for one package/in another recipe file based on whether another package is included in an image, you can have recipes (and their bbappends) respond to configuration settings. Two such mechanisms are FEATURES and OVERRIDES. In this particular case I would probably use EXTRA_IMAGE_FEATURES from local.conf (or maybe DISTRO_FEATURES or IMAGE_FEATURES directly if making a distro or an image recipe).
https://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#usingpoky-extend-customimage-imagefeatures https://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#var-FEATURE_PACKAGES In your example Package-B.bb do something like (needs testing, search the manual for similar snippets, …) SRC_URI_append = "${@bb.utils.contains('IMAGE_FEATURES', 'myfeature', ' file://0001-add-new-line.patch', '', d)}" Again this won’t ‘fix’ Package-A if someone just directly adds Package-B to IMAGE_INSTALL or otherwise directly or indirectly “does it the wrong way”, but you can create a “right way” for yourself/team.
