I think the best thing to do is change huge_pages='on' to log a WARNING and fallback to regular pages if the mapping fails. That way, both dev and prod can keep the same settings, since 'on' will have both visibility and robustness. I don't see a good reason to refuse to start -- seems like an anti-pattern.
