The reference patch is already in dunfell: https://git.openembedded.org/openembedded-core/commit/?h=dunfell&id=2246b0d7a71c69eb2e89c55991d1387069895466 > My colleague Tingquan gave it a try and the patch from Hardknott applies > cleanly on Dunfell. > > The documentation patch for Poky proposed by Quentin does not apply though. > But it is just that ref-variables.rst was renamed to variables.rst. Please see the documentation patch currently on the list for review: https://lists.yoctoproject.org/g/docs/message/1469 Both should be in the 3.1.9 release coming up in the next week or so.
