I was indeed trying to say that.
But on second thought: you should do whatever Gentoo usually does with
such configuration files. Consistency trumps any minor advantages any
particular approach might have.

That's a more reasonable size than your first example. Although this ...

... then begs the question: what's the advantage of having the
${S6CONFIGDIR}/system/config/seatd entry point at all? How much effort
does this save the admin over creating their own my_seatd service and
disabling the one you provide?
(Honest question, I don't fully grok s6.)

Being able to easily add custom services is a necessity anyway.

So maybe don't allow any customization (besides disabling) at all, ship

| #!/bin/execlineb -P
| fdmove -c 2 1
| seatd -n3 -u root -g seatd

and teach users to create new services with the 3rd line changed to
whatever they need.

HTH,
