@geerlingguy - just out of cutiosity, is any of this explained in repeatable steps people without "institutional knowledge" of this process can follow? By repeatable steps, I mean the list of cli commands in order.
Example
Step 1: execute "mkdir kernelfiles" //creates new directory
Step 2: "cd kernelfiles" //navigates into directory)
Step 3: sudo apt-get source XYZ --arg1 X --arg2 //downloads source
Step 4: execute "sudo apt install buildpackage1, buildpackage2" //installs neccesary tooling
Step 5: install kernel using ...
Not
Step 1: clone the kernel
Step 2: build the kernel
Step 3: some other vague descriptor
Would love to try it myself.
