None. Unfortunately, not everything that every developer might want to
know for every project can be documented.

Find the part of the code that triggers that error message, examine what
circumstances and data structures trigger it and modify suitably. Then
look where else that data structure is used and adapt as necessary.

You'd only have learned to do this if you'd used a debugger to step
through the flow of the code. I highly recommend that procedure.
init_forcerec() checks an environment variable and triggers the use of
generic kernels accordingly. Various other environment variables have
various other effects there and deeper in the code.
