I agree that essential environment variables and the like should be
specified in the PKGBUILD, but when I (briefly) looked at reproducible
builds a while back I took it a step further. My thought at the time
was to have a makepkg wrapper that would use a clean makepkg.conf so
that any makepkg variables would have to be specified in the PKGBUILD
as well. This wrapper would then record whatever environment
information was required itself. Given the variety of environmental
factors that will have to be recorded and reproduced for some
packages, I think it makes more sense to have a wrapper that does all
of the environment handling on its own without directly involving
