The question "How do you approach centralised patch management for Linux?" seems to fall pretty straightforwardly under the auspices of "Operations, maintenance, and monitoring".
Despite the fact that it uses the word "you" it really isn't a particularly subjective or opinion-based question (any more than most) and it isn't really a product question, either, since the guy doesn't say s/he wants a list of products; just a solution to the given (pretty common) ops problem.
I ran across it because I'm having a similar issue, and none of the provided answers are proving particularly helpful; an issue which I doubt would persist if the question were reopened (though I could be wrong).
I know it's less common for questions like this, so I should clarify I am not the original asker.
