I think it is extensible as we can just add new fields as needed, e.g.
for shell snippets to run at certain stages, or to support additional
ways of starting the daemon. But do you agree that the current proposal
is a reasonable “minimum feature set” for now, and to be extended later?

Is exec for forking mode and restart for non-forking mode? Just to make
sure I understand you here.

Ok, but that’s an issue with sys-v-init scripts, and we do not plan to
solve them here. But if you think that any “normal” daemon (i.e., those
daemons simple enough to use metainit) should have a /etc/default/*
file, that would be possible of course − just adjust the init script
generation script. (Current try on [1])

Thanks,
Joachim
