GuestSneezeOS Immutable Rolling

GuestSneezeOS is a robust, free-to-use ,lightweight,Immutable,operating system designed to bring the functionality of Valve's SteamOS to a wide range of devices, including desktops, laptops, and more. We aim to support all compatible computers (please check the system requirements). GuestSneezeOS is also less bloated than other distros (cough cough Qubes,Ubuntu,Debian).

Linux vs MacOS

These are reasons why macOS is inferior compared to Linux when it comes to gaming.

• No 32-bit support. The latest version of macOS is now 64-bit only meaning legacy native games will not run.
• Steam Play's Proton is only supported on Linux (not macOS).
• Old and incomplete implementations of OpenGL 4.1 and OpenCL 1.2
• No native Vulkan support.
• Linux has kernel-level optimizations for Wine.
• CrossOver Mac, a commercial Wine product, is one of the few ways to run games on macOS. It costs money and requires a new license yearly (or a very expensive lifetime license). Which as of today is open-source well its not open-source but it is in their website The community fork of Wine from CrossOver lacks support for some game launchers, codecs, and translation layers.

  Features

• Any computer with an AMD or Intel processor can run GuestSneezeOS.
• Compatible with different PC manufacturers
• Compatible with both UEFI and Legacy/BIOS
• Easy to build
• Steam Deck look and feel (Gamescope provided)
• KDE Plasma desktop environment is used for ricing (also SteamOS uses it)
• Compatible Many file systems

  Requirements

• 1. At least 2GB of RAM
  2. intel i3 or Ryzen 3 CPU('s)
• 2. A semi-modern CPU (Dual Core)
• 3. An Intel Or AMD,Nvidia GPU
• 4. At least a 10GB USB drive (for the installer)
• 5. At least 18GB of disk space (will use 16-18 GB depending on how much storage you have )

Passwords

SteamOS based Distros

Gaming Support

Open Gamepad UI for an open source video game console experience. Bottles for all Windows programs. EmuDeck for video game console emulators.

• Wine:
• 1. Proton is installed along with Steam for playing Windows games on Linux.
• 2. GE-Proton is installed along with the ProtonUp-Qt package manager for it. This provides better Windows games compatibility. -Game launchers:
• Steam. (Ofcourse it comes preinstalled)
• Lutris for all other games.
• Gamescope for a gaming session
• Opengamepadui for a gaming session

How To Dualboot

This are a few guides on how to Dualboot GuestSneezeOS with Windows

Windows Preperation For Dualbooting

• If Bitlocker is turned On then turn it off
• If Secure Boot is Turned On Turn it Off
• Create (Minumum 20 GB) Partition with Disk Management
• Right Click on the C: Partition
• Shrink Volume and select how much size should GuestSneezeOS Have (Minumum 20 GB)

Dualbooting

• Boot into the Live USB
• Once booted install it and select the Drive that you created (sda is C: and sdb is D:)

Troubleshooting

GuestSneezeOS not booting

• There are many different reasons why GuestSneezeOS may not be booting.
• Refer to WinesapOS's Detailed Macboot And Windows boot
• If using a USB Type-C cable, try flipping it upside down (180 degrees)
• BIOS
  • Older motherboards that do not support GPT partition layouts will not be able to boot GuestSneezeOS.

    GuestSneezeOS not being installed

    if this installer does not work try this (GuestSneezeOS 5+)

    sudo passwd root
    su
    cd ~/newbackup/
    sudo bash install.sh

    if it is still is not working either make your own installer or contact me

Building GuestSneezeOS

On Arch Linux

sudo pacman -Sy archiso git
git clone https://github.com/GuestSneezeOS/GuestSneezeOS/
cd GuestSneezeOS
./build.sh -v

On Debian

sudo apt update && sudo apt upgrade -y
mkdir ~/GuestSneezeOS
cd ~/GuestSneezeOS
sudo apt install debootstrap arch-install-scripts curl git
debootstrap --arch amd64 stable ./arch https://deb.debian.org/debian/
sudo mount --bind /dev ./arch/dev
sudo mount --bind /proc ./arch/proc
sudo mount --bind /sys ./arch/sys
sudo chroot ./arch
pacman -Syy
pacman -S archiso git
git clone https://github.com/GuestSneezeOS/GuestSneezeOS
cd GuestSneezeOS
./build.sh -v
exit
sudo umount ./arch/dev
sudo umount ./arch/proc
sudo umount ./arch/sys
ls ~/GuestSneezeOS/out

Supporters of the Project

• GuestSneezeOSDev : Founder and Project leader (Builder,Designer and Coder of the Project)
• nyxiereal : Newer README (No longer supporting the project)
• LukeShortCloud : winesapOS (we use the repository in the pacman.conf)
• Gabriel Sanhueza (gsanhueza/archisomaker) (Made the build script for GuestSneezeOS)

How to disable READONLY file system

sudo steamos-readonly disable
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman -S <package name>

Make sure to do this if you are sure about what you are doing because this might break your system I reccomend instead Flatpaks, AppImages, or Distrobox

Setting up Docker

Enable the netfilter module:

sudo modprobe br_netfilter
echo "br_netfilter" | sudo tee /etc/modules-load.d/netfilter.conf

Enable IP Forwarding :

sudo sysctl net.ipv4.ip_forward=1
echo "net.ipv4.ip_forward=1" | sudo tee /etc/sysctl.d/ip_forward.conf

Create an .nspawn file We are going to create a systemd .nspawn configuration which we can use later by passing --machine name when creating containers :

sudo mkdir /etc/systemd/nspawn
sudo nano /etc/systemd/nspawn/archlinux.nspawn

and when you reach the GNU Nano in this part add this code

[Exec]
Boot=true
Capability=all
SystemCallFilter=add_key keyctl bpf
Bind=/dev/fuse

[Files]
Bind=/home
Bind=/mnt
Bind=/etc/hosts
Bind=/etc/passwd
Bind=/etc/shadow
Bind=/etc/group
Bind=/etc/gshadow
Bind=/etc/subgid
Bind=/etc/subuid
Bind=/etc/sudoers
Bind=/etc/sudoers.d
BindReadOnly=/etc/resolv.conf
BindReadOnly=/tmp/.X11-unix

Also give any containers using the .nspawn access to fuse:

sudo systemctl set-property systemd-nspawn@archlinux DeviceAllow='/dev/fuse rwm'

If you made the user directory mounts read-only, youll need to add the Docker Container on the host and/or service

sudo groupadd -r docker
sudo usermod -aG docker deck
sudo systemctl restart sddm

Install Docker

sudo pacman -S docker
sudo systemctl enable docker --now

then Reenable read-only for the system not to break

sudo steamos-readonly enable
sudo journalctl -xeu docker

you should be able to use docker without root

docker run -it --rm --name alpine alpine:latest /bin/sh
