Her comment here acknowledges this, but this will cause problems when /tmp is mounted noexec, which is fairly common for servers: https://github.com/jart/cosmop

I suppose this level of portability is more a feature if you're shipping to PCs anyway, though. If you're deploying to servers, you know the arch and OS ahead of time and there is no obvious downside I can think of to just targeting it directly.
