With my distro hat I have to say I have no interest in chasing more reproducible knobs for the kernel -- the current trend in 99% of the projects is that just setting SOURCE_DATE_EPOCH "just works" and the every non-default option that is required is work for people to track, enable in various packaging frameworks, backport to old kernels, update if it ever changes... I could understand a new option "toggle everything reproducible" that would select this, even if it doesn't do anything else right now (perhaps also complain if KBUILD_BUILD_TIMESTAMP isn't set?), but I can't say I'm thrilled about a new option pahole-specific that would have to be individually enabled. (I guess that means I've just volunteered to add both... perhaps next year when I find time, for now the distro pahole patch toggling reproducible if SOURCE_DATE_EPOCH is set will do) -- Dominique Martinet | Asmadeus
