I was wondering what's the search order e.g. if the same .patch is present in 2 different directories. bitbake -e busybox | grep ^FILESPATH= To my surprise I saw (after some cleanup this): FILESPATH=" busybox/busybox/poky: busybox/busybox-1.24.1/poky: busybox/busybox/poky: busybox/files/poky: busybox/busybox/multi-v7-ml: busybox/busybox-1.24.1/multi-v7-ml: busybox/busybox/multi-v7-ml: busybox/files/multi-v7-ml: busybox/busybox/armv7a: busybox/busybox-1.24.1/armv7a: busybox/busybox/armv7a: busybox/files/armv7a: busybox/busybox/arm: busybox/busybox-1.24.1/arm: busybox/busybox/arm: busybox/files/arm: busybox/busybox/: busybox/busybox-1.24.1/: busybox/busybox/: busybox/files/ " I assumed that the order in which the directories appear has to do with the preference, but various directories appear multiple times like busybox/busybox/poky: busybox/busybox/poky: <-- busybox/busybox-1.24.1/poky: busybox/busybox/poky: <-- What's the order of preference supposed to be if someone throws a patch with the same name in 2 different directories?

I tried this locally and got: poky/meta-poky/recipes-core/busybox/busybox/poky poky/meta/recipes-core/busybox/busybox-1.24.1/poky poky/meta/recipes-core/busybox/busybox/poky poky/meta/recipes-core/busybox/files/poky poky/meta-poky/recipes-core/busybox/busybox/qemux86-64 poky/meta/recipes-core/busybox/busybox-1.24.1/qemux86-64 poky/meta/recipes-core/busybox/busybox/qemux86-64 poky/meta/recipes-core/busybox/files/qemux86-64 poky/meta-poky/recipes-core/busybox/busybox/qemuall poky/meta/recipes-core/busybox/busybox-1.24.1/qemuall poky/meta/recipes-core/busybox/busybox/qemuall poky/meta/recipes-core/busybox/files/qemuall poky/meta-poky/recipes-core/busybox/busybox/x86-64 poky/meta/recipes-core/busybox/busybox-1.24.1/x86-64 poky/meta/recipes-core/busybox/busybox/x86-64 poky/meta/recipes-core/busybox/files/x86-64 poky/meta-poky/recipes-core/busybox/busybox/ poky/meta/recipes-core/busybox/busybox-1.24.1/ poky/meta/recipes-core/busybox/busybox/ poky/meta/recipes-core/busybox/files/ where you can see one is in "meta-poky" whilst the other is in "meta". Also, this variable works like PATH, the first found wins. You can therefore put the same patch in each of these directories and it will use the first one found. Even if there were duplicates, the system would still then work.
