I know I'm a bit late to this, but Eric's quoting me, and I thought
I should stand behind my words publicly.

I often find myself confronted with systems that I didn't build, haven't
maintained, have no documentation for, and are broken in odd/puzzling
ways. There's also sometimes a bit of duress due to externally imposed
time constraints. I of course don't expect anyone else to solve those
problems, but it would be awfully handy if there was a breadcrumb trail
to follow.

So to borrow Eric's phrase, "getting more information in userspace when
operations fail", would be an entirely good thing. I'll defer entirely to
others in the discussion thread about how that might be best accomplished,
but I'd like to express my full support for the end goal.
