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.

Join the club :-/  You now know pretty much as much as I do about
systemd --- which ain't much!
