I have listened to the community
I will reintroduce installtointernal, I have made upgrading from 8.2 possible with the new kernel
The build will stick with the new kernel and not go back to kszaqs for now at least, a number of video issues have been resolved recently by afl1 and there is a patch available for the audio issues that I am looking into, initial testing has shown improvements over kszaqs kernel, I do believe it is best to move forward and to try and fix the issues rather than just revert.
I have also fixed the issue with Kodi starting with a black screen when using a 4k TV on fresh installs.
