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.

secureblue: Hardened Fedora Atomic and Fedora CoreOS images (secureblue.dev)

Not many people have heard about secureblue, and I want to spread the word about it. secureblue provides hardened images for Fedora Atomic and CoreOS. It's an operating system "for those whose first priority is using linux, and second priority is security."

secureblue provides exploit mitigations and fixes for multiple security holes. This includes the addition of GrapheneOS's hardened_malloc, their own hardened Chromium-based browser called Trivalent, USBGuard to protect against USB peripheral attacks, and plenty more.

secureblue has definitely matured a lot since I first started using it. Since then, it has become something that could reasonably be used as a daily driver. secureblue recognizes the need for usability alongside security.

If you already have Fedora Atomic (e.g. Secureblue, Kinoite, Sericea, etc.) or CoreOS installed on your system, you can easily rebase to secureblue. The install instructions are really easy to follow, and I had no issues installing it on any of my devices.

I'd love more people to know about secureblue, because it is fantastic if you want a secure desktop OS!

Anything in particular that wish you to get over from Bazzite?

Very minor things which may or may not be already available in Secureblue:

LatencyFleX, vkBasalt, MangoHud, and OBS VkCapture installed and available by default.

Patched Switcheroo-Control fixing default-broken iGPU/dGPU switching.

HDR available in game mode and full hardware accelerated codec support for H264 decoding.

And the last one that I'm on the fence if would be a good addition or not the ujust based on the just project.
