During the call to expandVarref('LAYERDIR'), whichever append/prepend/remove apply at the moment are used by getVar(), and then they are all dropped by serVar(), including the ones whose OVERRIDES would come from layers parsed later 99611 1 randy.macleod 2024-09-05 14:36:34 +0000 See discussion on mailing list. 99612 2 yoann.congal 2024-09-05 14:38:28 +0000 https://lists.openembedded.org/g/bitbake-devel/topic/108158309 106794 3 richard.purdie 2026-09-10 15:13:03 +0000 We are thinking of changing the way layers get added and we could try and take this into account when we do that.
