Do you really consider these weird and complicated instructions a 'fix'?

Why don't you put the relevant stuff on Github and implement a simple script that does everything that's needed. I proposed that already in your forums and pointed you to longsleep's work for Pine64 you could easily adopt: https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_kernel.sh
