We need to be mindful that we need to resolve this to unblock the other language changes and feature creep here is potentially problematic. I do think it is worth trying to improve things rather than blindly allowing the horrible syntax in this variable to continue though. The test case we have for this currently is: WHITELIST_GPL-3.0:pn-core-image-minimal = "bash" so I'd wondered about an alternative of: INCOMPATIBLE_LICENSE_EXCEPTIONS:pn-core-image-minimal = "bash:GPL-3.0" which matches the current functionality, removes the issue that the name of the variable is unknown without iterating every possible license name and makes it clear where it is applying to. I don't really like INCOMPATIBLE_LICENSE_ALLOWED_RECIPES since: a) it is long b) it refers to recipes when it works against packages (INCOMPATIBLE_LICENSE_PACKAGE_EXCEPTIONS is more correct but still long) I do like it mentioning INCOMPATIBLE_LICENSE in full since it works in conjunction with that variable and that is definitely not clear from the current WHITELIST_XXX until you look at the code. I'm still of the opinion the AVAILABLE_LICENSES variable is something we should be aiming to remove ultimately too, it has horrible issues with layers changing hashes for all recipes. Cheers, Richard
