CachyOS Released With BTRFS As The Default Filesystem

By sk

The CachyOS team has announced the seventh release of CachyOS this year, introducing several significant updates and improvements. CachyOS combines the robust foundation of Arch Linux with specialized optimizations to deliver a high-performance, secure, and user-friendly computing experience.

CachyOS Overview

CachyOS is a Linux distribution based on Arch Linux, designed with a focus on speed and security optimizations. The default Linux kernel is highly optimized using the BORE (Burst-Oriented Response Enhancer) scheduler.

Additionally, the desktop packages are compiled with LTO (Link Time Optimization), x86-64-v3 and x86-64-v4 optimizations, as well as various security flags and performance improvements.

Key Features

  • Optimized Kernel: The kernel is fine-tuned for enhanced performance and responsiveness using the BORE scheduler.
  • Optimized Packages: Desktop packages are compiled with advanced optimization techniques to ensure maximum efficiency and security.

Desktop Environments and Window Managers

CachyOS offers a wide range of desktop environments and window managers, including:

  • KDE
  • Xfce
  • CuteFish
  • i3wm
  • Wayfire
  • LXQt
  • OpenBox
  • Cinnamon
  • UKUI
  • LXDE
  • MATE
  • Budgie
  • Qtile
  • Hyprland
  • Sway


The distribution includes Cachy-Browser, a Firefox-based browser with additional security enhancements and performance optimizations.

Installation Options

CachyOS provides both graphical and command-line installers.

CachyOS latest edition ships with significant improvements. Some of the important feature updates are given below:

01. T2 MacBook Support

The default CachyOS Edition now supports T2 MacBooks. Wi-Fi and Bluetooth won't work out of the box due to Apple's closed-source firmware, but instructions are available for enabling these features after installation.

02. New "cachy-chroot" Script

The ISO includes the "cachy-chroot" script to guide users through the chroot process and proper partition mounting. It also detects BTRFS subvolumes, helping users identify existing subvolumes.

Additionally, the ISO now uses the mkinitcpio microcode hook and supports copytoram, which speeds up the overall experience if there is enough available RAM. The ISO requires the latest Ventoy release (1.0.98).

03. NVIDIA Card Enhancements

Services have been enabled by default to ensure proper sleep functionality and apply necessary NVReg settings, which address graphical issues during sleep on Wayland.

The new NVIDIA 555 Driver supports explicit sync, greatly improving the Wayland experience. Compositors have been patched to support explicit sync as well.

04. BTRFS is the new Filesystem

BTRFS is now the default file system instead of XFS, though users can still choose and configure other file systems.

05. Firewalld is Replaced with UFW

In this new release, the firewall has been switched from firewalld to ufw, offering a simpler setup for most users.

06. Handheld Edition Updates

The CachyOS Handheld Edition is now stable, with enhanced hardware detection and configuration for devices like the Steam Deck, Legion Go, and Rog Ally.

While not yet tested, it should also support Ayaneo devices. Ongoing communication with the company aims to gather more information.

07. Updated CachyOS Wiki

The CachyOS wiki has been completely restructured to provide more comprehensive information for users. Some pages are still being completed and will be updated within the month. Users can visit the new wiki here: CachyOS Wiki.
