Patch 1/2 adds the depends, but there's no way to disable it. Without defining the variable that you have in patch 2/2, you can't upgrade the kernel packages .. which makes it not only a new variable, but a new requirement when working with the kernel recipes/packages. People have been upgrading the kernel before either of these patches (I can't say that I do very often .. but I know that users of the commercially supported distros do) .. unless it has been inadvertently broken, or there are more patches floating around that I've not seen. what is the upgrade behaviour with neither of these patches applied ? .. that's the behaviour that I'm most concerned about maintaining. Also, if we were to introduce something like this, the series needs to have documentation updates along with it .. or we'll surely forget to document it and catch people by surprise :( Bruce > >> This was the simple and cleanest way I could think of to achieve the my >> scenario.
