It’s all in the man pages, which are also available online at
<https://systemd.io/>

I don’t edit most of them regularly either. There are lots of
different *nix admin/development things I do, but not frequently
enough to have memorized them. You get used to knowing how and where
to look things up.

In my undergrad physics classes, all the exams were “open book” -- you
were allowed, nay, expected, to bring a copy of the textbook to the
exam. I treat my admin/development work the same way: there’s no shame
in continually looking up docs, particularly nowadays when everything
is available online.

Fine if that’s the only thing in your rc.local, not so fine if you
start putting multiple things there. (Just another aspect of the
hodgepodge of bits and pieces that make up sysvinit, that have trouble
scaling to more complex real-world uses.)

Yes, there is such a service -- part of the sysvinit support, for now.
