Yes. That is exactly the right way to do it. In fact, there's a
way you can only make changes such as adding a param (but not removing;
that DOES require wholesale overriding) so that you don't have to
maintain the entire separate copy, which might then diverge with nice
changes across updates. On the other hand, it can be nice to have
absolute control over what happens.
Yes, extending or overriding a unit is part of systemd’s design. Often
drop-in snippets allow you to only change specific things, so you get
the other updates, in case the software (often distribution package)
changes something.
You can easily use `systemctl edit …` to do extend or override a unit
[1][2].
Kind regards,
Paul
