@tlaurion @mkukri And I personally respect the hell out of the fact that he actually sat down to read lbmk, and even mentored other Heads developers about the various idiosyncrasies of my build system.
Libreboot's build system is extremely insanely efficient but very unforgiving in its design. It's the most conservative possible design for what it does, and works differently completely than most build systems; the logic in Heads's T480 integration is based on lbmk's implementation in Libreboot.
