From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

A new CachyOS snapshot for July 2024 is out today with various improvements and some exciting new features, especially for AMD users, as well as the usual bug fixes and other changes to improve your experience.

Starting with this release, CachyOS will automatically enable a software repository on new installations that will be used to provide the best performance for AMD Zen 4 and Zen 5 machines. In addition, the ISO now features automatic architecture checks for the Zen 4/Zen 5 repository and CachyOS’s hardware detection tool (chwd) received support for AMD GPUs for better detection of official ROCm-supported GPUs.

It's a customized Arch Linux. Basically manjaro, but with ~~XFS~~ BTRFS file system (as mentioned in the release note )

BTRFS is now the default selected file system instead of XFS. The XFS file system and all others can still be selected by the users and configured.

It used to default to XFS, according to ZDNet

CachyOS gets part of its speed by defaulting to the XFS file system. This is a curious choice for a desktop file system, I'd argue, mostly because XFS is a journaling file system designed to support very large files and ensure the file system's integrity in the case of system crashes. XFS has been around since the early '90s and has been employed by large servers and storage arrays. - zdnet.com

if you've already been exposed to Linux and are looking to jump on board the Arch Linux train, CachyOS is a great option.

It defaults to BTRFS with more recent releases

Thanks for pointing out. I've edited the comment

They also ship ZFS out of the box, which makes their kernels my go-to solution for the systems I want to boot off ZFS.

It also compiles packages with newer architecture feature support than mainline arch. All of its packages are compiled for x86_64-v3 and x86_64-v4, as compared to the x86_64-v2 of standard arch. This improves performance at the cost of older CPU support
