Anyway, here's the original README:
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.
script.sh - The main script that strips away systemd
LICENSE - Repo's licenses
UPGRADING.md - A guide on upgrading Debian and how its mirrors work in general
NETWORKING.md - A guide on connecting to the internet using Debian with sysvinit
README.md - This file, explaining what is in the repo
SUDO.md - A guide on getting sudo to work
SYSVINIT.md - A guide to strip away systemd
this is how package names and components will be presented
this
is how commands will be represented
$ <command>
means that the <command> should be ran as a regular user
# <command>
means that the <command> should be ran as root
(please read the SUDO.md file if you don't know what i just said)
