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.

19 days ago I announced my plans here on Lemmy and after four weeks and ~300 hours in total, I can finally share the first ISO of my project with this community. ~~"sometime next week" yeah that was optimistic lmao~~ I want to thank you again for the feedback on the initial announcement and I can say I tried my best to address and implement a lot of your suggestions!

For the people that haven't read the last post, this is the basic gist of it:

Unlike immutable distributions that lock you out of the native package manager and force you into sandboxes, Plutonium-239 keeps the core Arch experience intact. You still get the bleeding-edge Arch repositories and the power of the AUR but all of that with a 5-20% performance boost from a heavily optimized kernel and the peace of mind of an unbreakable safety net underneath.

For the ISO and the in-depth technical documentation, please visit my website at the link in the title!

The 0.0.1 version is a pre-release/in-development version meant for experienced people interested in this project. I tested it extensively and I'm running it for a few days now on my Thinkpad myself, however I can IN NO WAY guarantee that this is 100% viable to daily-drive just yet.

I'm very thankful for every person that considers testing this distro in a VM or on a secondary PC to contribute to the development of this project. Any feedback is appreciated and I hope my work can be of value to you!

Edit: from the feedback that was pm'd to me so far it seems like it's working fine when it's running but two people had issues with the hardware detection during the install. If you are experiencing a similar issue, please send me your hardware specs and the output of the log where it failed and I'll be able to make it more robust!

Well, it were four 80 hour weeks and I "only" reverse-engineered the way Fedora makes their distro atomic with ostree but adapted to Arch. I did try to stay true to the Arch philosophy of keeping it minimal otherwise so it wasn't that big of a project!

Edit: Sometimes I had to spin up Qwen 3.8 27B because the error codes the installer threw out were literally humanly unreadable so I had no clue what even went wrong but other than that it was by hand lmao

LLMs are good for a few things. One of them is parsing human unreadable errors. I approve of this.

I don't like black and white thinking and while I fucking hate LLMs in general, as 95% of times they are used for all the wrong reasons, I do have an Intel B70 for cases like these where current search engines just lead to nothing.
