Does it work better when the AI is instructed to describe a method of answering the question, instead of answering the question directly?
For example, in this specific case, I am enough of a domain expert to know that this information is accessible by running `man systemd.service` and looking for the description of command line syntax (findable with grep for "ExecStart=", or, as I have now seen in preparing this answer, more directly with grep for "COMMAND LINES").
That's a much better option since the LLM is no longer the source of truth. Unfortunately, it only works in cases where the feature is properly documented, which isn't the case here.
