I read [a question about `systemd`][1]. The question is good, the answers are good.

When reading it, I realized that I had a similar question, but phrased differently. The original question is 

> modify systemd unit file without altering upstream unit file

and I would have asked 

> are systemd configuration files cumulative?

None of the wording is better - they both raise the same problem and have the same answers. The second one is obviously not indexed by Google.

**It is a good practice to write a question knowing that it is a duplicate for the sake of increasing the likehood of having it found?**

As a side though, it may be interesting to have the option to add alternative questions to a question in order to do what I am asking for without creating duplicates.
