the override you are deploying is wrong so this assignment in effect is noop.

SRC_URI_append = “ file://XYX.patch” is what will work. you can place this in a bbappend in your own layer
or you can add the same to main recipe as a patch on top. if you need to use overrides then make sure

SRC_URI_append_<override> is used and override is one of items in OVERRIDES variable to check the overrides you have
you can

bitbake -e busybox | grep -e “^VERRIDES=“

which should give you a list of overrides separated by ‘:’

Of course I could just copy one to another, but then there's the problem of updating files later on. Therefore, unless there is another option that I haven't considered, I might look at refactoring everything into a .inc file and have two different  recipe names of which I can then include seperately in the respective images.
