  • UPDATE

    I took your suggestions to heart and updated the website to reflect the changes I implemented today. The big change is that I found a way to keep pacman fully intact and functioning, but make it apply the changes atomically. So now this isn’t just limited to Flatpaks, but LITERALLY Arch Linux but made atomic.

    The new intro reads:

    “Plutonium-239 is Arch Linux, made atomic. It combines the rolling release model of Arch Linux with an atomically updated root filesystem inspired by SteamOS on top of the heavily optimized CachyOS performance kernel. Unlike immutable distributions that lock you out of the native package manager and force you into sandboxes, Pu-239 keeps the core Arch experience intact. You still get the full power of pacman and the official Arch repositories, with the peace of mind of an unbreakable safety net underneath.”

    For more information, please check out the updated “How it works” section. Thank you all a lot for the feedback!

    I’m currently working on one, will release the website this weekend and the first public in-development build next week. I’m combining the kernels and CPU-specific optimizations from CachyOS (compiled and hosted myself to be in line with their repo policy and licenses) combined with the way SteamOS makes Arch-Linux atomic/immutable, implemented a little more to the way Fedora Silverblue does it. So pretty much unbreakable PLUS fast and optimized.
