One might think so, yes but I just changed the order in bblayers.conf to: ``` ${TOPDIR}/../sources/meta-mender/meta-mender-core \ ${TOPDIR}/../sources/meta-security \ ${TOPDIR}/../sources/meta-intel \ ``` But `bitbake -e` now shows `EFI_PROVIDER="systemd-boot"` again. Don’t know why tbh. Thanks for your help, though. ---

It’s probably the layer priority. Just reordering them in bblayers.conf won’t change that. You can use `bitbake-layers show-layers` to dump out all the layers and their priorities. Drew ---

You’re right, but mender has a higher priority: ``` meta-mender-core /root/build_dir/build/../sources/meta-mender/meta-mender-core 6 meta-intel /root/build_dir/build/../sources/meta-intel 5 meta-up-board /root/build_dir/build/../sources/meta-up-board 6 ``` ---

Ok, then I propose you post the output of the command I suggested earlier, so we can see how it’s actually calculated: ```bash bitbake -e core-image-minimal | grep -B100 EFI_PROVIDER= ``` ---

I guess it has to do with ordering of the ‘?=’ operations. I think you may just have to force it set in your local.conf. ---

Yes, that’s what I’m doing currently. Not perfect, but it works. ---

Interesting, so the priority of `?=` is reverse, it’s the first one that stands, instead of the last one. This almost seems like a bug in Bitbake, it breaks layer priority. I’m thinking it means that maybe it’s better if meta-mender does not mess with the default, but instead sets it only when it’s really needed.
