As I'm currently learning python I'm eagerly awaiting your answer there now. ;)

I think a user with experience of the exact hardware setup – which would be necessary to write a truly good answer – is hard to find. I'd like to raise another question: Is it after all worth the trouble if (IMO) OP should just try installing and come back with an error message just in the rare case that it doesn't work out of the box?

If I do such a major edit to any of the existing questions the existing answers won't fit any more, that seems unfair and I didn't dare – do you really consider changing a specific question to adress the issue generally the best way? How would you choose which?

I see three options: No – leave everything as it is; Merge – merge the new answers into the old question and edit it (see muru's answer); Yes – maybe edit and improve the new one.

@Joachim Aside from this question there's exactly one other question from you (this), where you added information in a comment rather than editing the question. Did you take the tour?

What other posts are your refering to? As far as I can see it you didn't post anything besides this question yet – do you have multiple accounts?

It works well in the CV queue: i.sstatic.net/LPRLA.png
