!!! Important !!!

You can now get the sysvinit Debian ISO, which sets
up everything for you during the install, this repo
will still stay up for manual sysvinit installation or
maintenence of a sysvinit Debian install in general.

Download the ISO from here:

Intro

Debian is a really good distro, but if stop jobs and bad code
annoy you, you will find that it having systemd is annoying.
Most people will say that Debian is systemd-dependent
that is a lie, this guide will run you through the process
of installing sysvinit on Debian stretch or buster.
