What I meant by Perhaps it is different in serverfault than the rest of stackexchange? is that, in SO for example, you wouldn't answer a question like, e.g., "How do I pass by ref in Python" by saying "Use Perl". That type of thing is acceptable here for reasons you have stated.

Yea his analogy made lots of sense to me and helped me get what he was getting at.

Thanks. Seems like SF leaves room for subjectivity when it comes to "problem the question is trying to get at". However, when I think about it, sysadmin work overall allows for more subjectivity over, for example, programming. Makes sense. Thanks again!

What makes it the "wrong" site? I.e., in what cases would a mod migrate from "Unix and Linux" to "Serverfault" and vice versa?
