Parent article: Moving beyond fork() + exec()

Really? So you can copy a UWP from Windows 11 to Windows XP and it will work?

Have you built for other OSes? Down level targeting of glibc is a whole universe of pain that's just absent on other systems. That you need something as enormous as Yocto (built for generating embedded device immutable images, not distribution packages) to get a semblance of downlevel compatibility is a further indictment of the glibc model.

Cost vs benefit of extended discussion

I vaguely recall that, once upon a time, this was an article about fork() and exec(). This discussion has clearly strayed far from that topic. Perhaps more to the point, though, it seems to be becoming increasingly circular. Perhaps it's time for all of the parties involved to let it go?

I will charitably assume you hadn't seen Jon's comment asking for this thread to wind up, but it has in fact wandered far off topic, and we should leave it where it lies.

Nope. Not an UWP program. Because the point was, these things work everywhere, _if_ you code and build for the right target.
