Not really. What’s the first step to writing a new sysvinit script?
Copy/paste a whole bunch of boilerplate from an existing script. Why?
“Just in case” ...

I’ve done several of those. Here’s an example (not one of mine)
<https://web.archive.org/web/20240711140744/https://list.waikato.ac.nz/archives/list/wlug@list.waikato.ac.nz/thread/BIAW7GY4KGPUGWIIRWNMBE5JSUVT2VWX/>
which is instructive because of its simplicity: it shows how systemd
can really make things easier to express than sysvinit.

Personally, all the ones I’ve done have been quite small -- less than
a dozen lines each. And each line was put in because it had a purpose
that I understood.

The one pitfall I did encounter was the difference between “After=”
and “Requires=” lines: one specifies timing, the other specifies
dependency, and if you want both, you need to specify both. ;)
