On errno

All,

I've often found myself going over the existing error codes
in search for one that seems to match best or is the least
unsuitable. This begs the question: what is stopping us from
adding new error codes?

With so many drivers returning ENXIO whenever something (i.e
anything) is wrong, how meaningful is ENXIO in diagnosing
problems?

What do the various standards dictate or allow us to do?
