Is it OK to ask questions like "what is the etymology of hdparm command name?"?
General topic matches https://askubuntu.com/help/on-topic ("Using and administering official Ubuntu flavors", "Running third-party applications", "Development on Ubuntu").
It is not explicitly rejected by https://askubuntu.com/help/dont-ask
Main problem that I see is that while for some commands there may be some obviously correct answer for others the best answers is "it appears to be unclear" and it is impossible to guess it before asking (except cases of self-answered questions).
