misc: A guide on different init systems. (working: runit, sysvinit)

[aneeshlingala]

Well, you might be bored of systemd, or you hate it because its too bloated, or you have a different reason, this is your special guide on how to install different init systems

This only works on Debian Bullseye, I will update the guide when new versions are released.

1. Info about init

---

You may ask, "What is init?".

The answer is that init is a very crucial process that has to be run as PID 1 or it will not start. It is the master process that starts all of the child processes and sets up the system for normal use, this usually happens with no user input. Usually init hands over its process to another init system, runit, sysvinit, systemd, s6, etc, which usually has more features, but init can also run on its own with initscripts, but sometimes a pain to maintain sometimes, pretty cool right?

Working display managers SDDM, installed by running the command sudo apt install sddm | Tested & recommended SLIM, installed by running the command sudo apt install slim | Not tested but another option & default in Devuan GDM, installed by running the command sudo apt install gdm3 | Tested & another recommended option

Unusable display managers LightDM, (Can somebody can help me on this? Seems to work on devuan out-of-the-box but still not working?)

2. Enough info, lets start installing

NOTE: IF YOU DON'T FOLLOW INSTRUCTIONS CORRECTLY, IT COULD RUIN YOUR INSTALL.

Install git, nano, ucf and wget by running the command sudo apt install git nano wget ucf Make sure you cd to your home directory, cd ~ Now, run the command wget http://ftp.us.debian.org/debian/pool/main/o/orphan-sysvinit-scripts/orphan-sysvinit-scripts_0.07_all.deb Now, clone the repository, git clone https://git.devuan.org/farmatito/migration Now, run cd migration Now run sudo bash migration.sh Now it is going to output "Warning use at your own risk. BACKUP YOUR DATA FIRST!!!", on this prompt type "y" to continue. Now, it is going to ask "Do you want contrib repos to be included in your apt sources? [y|n]", on this question type "y." Now, it is going to ask "Do you want non-free repos to be included in your apt sources? [y|n]", on this question type "y." After some time, it is going to ask "Do you want to edit /etc/network/interfaces now? [y|n]", on this question type "n". Now reboot by running the command sudo reboot Now, when your back in the system, login, and run the command sudo nano /etc/apt/sources.list Now, remove any other entries that are not pointing to "devuan.org". Now, you are not going to have network, don't worry, run the command cd ~ && sudo dpkg -i orphan-sysvinit-scripts_0.07_all.deb Now run, cd /etc/init.d Then, run sudo bash network-manager start && sudo bash networking start Once you are connected to the internet, run sudo apt update Then, run sudo apt reinstall base-files && sudo apt upgrade Now, run sudo apt clean Then, run sudo apt autoremove You can stop here if you want sysvinit, but if you want runit, then continue. For runit, run sudo apt install runit-init init, if it tells you to input "Yes, do as I say!", then do it, it is safe. Then, run sudo reboot

3. Cleanup First run cd ~ Then run rm -rf migration After that, run rm -rf orphan-sysvinit-scripts_0.07_all.deb

Well, this is the end of the guide, I hope you have a good journey on your new init system, comments are open for suggestions, comments or questions.
