It currently sets environment variable for the builder daemon by setting `allowSubstitutes = 0` if `(not substitutable?)`. If non-substitutability were propagated by doing something like instead setting `allowSubstitutes = 0` if `(not substitutable?)` or if `(not (every substitutable-derivation? inputs))`, wouldn't this suffice to ensure that an initrd which contains non-substitutable inputs is properly marked non-substitutable?

This has effectively already been answered.
