Thanks for your guidance. You are right, it was relatiely straight forward to build LibreELEC. Thanks for that. I built a Ubuntu 20.04 server and followed the instructions here. I was able to build 9.2 branch and 9.8 (master). It has been a long learning curve not necessarily hard just long because it took nearly half a day when I tried to build different packages. But I have succeeded in building the branches I mentioned before.
My current problem is that when I search for package.mk, I am getting maybe hundreds of hits. Could you provide a bit more specific guidance as the where I need to make those two changes.
Thanks
