CachyOS Repository Installer

This script automates the process of adding the CachyOS repositories to any Arch Linux-based distribution. CachyOS provides heavily optimized kernels and packages tailored for modern CPUs.

The script automatically detects your CPU's supported architecture (such as x86-64-v3, x86-64-v4, or znver4/5) and configures pacman to use the most optimal repositories for your specific hardware.

Features

• Automatically detects CPU instruction set capabilities (x86-64-v3, x86-64-v4, znver4/5).
• Installs CachyOS keyring and mirrorlist.
• Backs up your current /etc/pacman.conf before making any modifications.
• Configures /etc/pacman.conf with the appropriate CachyOS repositories.
• Refreshes pacman databases automatically.
• Provides an easy removal option to revert changes.

Requirements

• An Arch Linux-based distribution (Arch Linux, EndeavourOS, Manjaro, Garuda, etc.)
• sudo or root privileges
• git (to clone this repository)

Step-by-Step Usage

1. Clone the repository

First, download the script to your local machine:

git clone https://github.com/your-username/cachyos-repo.git

(Note: Replace the URL with your actual GitHub repository URL once uploaded)

2. Navigate to the directory

cd cachyos-repo

3. Make the script executable

chmod +x cachyos-repo.sh

4. Run the script

Execute the script with root privileges to install the repositories:

sudo ./cachyos-repo.sh

Alternatively, you can explicitly use the install flag:

sudo ./cachyos-repo.sh --install

5. Install CachyOS Kernels and Packages

Once the script finishes successfully, the repositories are added. You can now install CachyOS kernels or other optimized packages. For example:

sudo pacman -S linux-cachyos linux-cachyos-headers

Important: After installing the new kernel, you must update your bootloader and reboot your system to apply the changes.

If you are using GRUB, you can update it with:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Finally, reboot your computer and make sure to select the linux-cachyos kernel in the GRUB boot menu.

How to Remove

If you want to remove the CachyOS repositories and revert your pacman.conf to its original state, run the script with the --remove flag:

sudo ./cachyos-repo.sh --remove

This will restore the backup of your pacman.conf, remove the CachyOS mirrorlist and keyring, and perform a system update to sync repositories.
