As a rule of thumb, the build environment should never change so that
things that derivations that succeeded one day still succeed years
later.

So my take is that we should live with this discrepancy forever and
ever.

(Note that the unprivileged daemon does introduce some discrepancies,
and this is something we should fix as much as possible.)

Thanks,
