I've just made an answer to the question, and referred to the proper tutorial that shows how to do exactly what the asker wants to do. I was not plagiarising a tutorial, but briefly described all the parts involved. What is the problem with my answer?
A couple of reasons:
Here's another meta Q&A more specifically about "Raspbian", although it is pretty clear what is really meant is general linux questions. In my answer there, I explain that part of the problem is that we do not have expertise in sufficient volume for us to field all such questions and ignore the existence of Unix & Linux, just as we do not have expertise in sufficient volume to ignore the existence of the larger Electrical Engineering. Answering this question in the way it was answered does not provide anything hopeful in this sense, as I will try to explain.
If that question were migrated to U&L, it would be closed as a duplicate because it is something which has been dealt with many times in many places, as your response indicates.
It's worth noting that there's already at least one exact duplicate here with more information in it, so there are multiple reasons for this to have been closed.
In cases like this, it is fine to give someone a quick link and explain this is well documented and easily researched topic if you know what to search for. This is all your "answer" was, so I converted it to a comment and closed the question.
There is no need of anything more than that and looking at the final comment, it seems the O.P. is happy.
If the question were one which was more unusual (e.g., because it involved more particularly unique aspects of the pi) and one which has not been sufficiently dealt with elsewhere online and someone was willing to do it here, then great.
We have a lot of questions that go unanswered because they do fall into this latter category. If people have time to answer questions, it would be much better if they make an effort to research and answer those as best they can rather than cherry picking things quickly -- this just leads to exploiting the system in a mostly unhelpful way, which is why it is also frowned upon on, e.g., our parent site Stack Overflow.
