<shrug> kernel build doesn't have to use it - if I mount a writable layer atop of the clean tree and build in the resulting tree, build system doesn't need to have any idea of that fact. That's the point - you are emulating the thing that is generally useful and belongs to different layer - namely, the kernel.
