After months of work I’m finally releasing Margine OS, my own atomic Linux distro, and the short version is that it’s fast.
It’s built on Bluefin DX, so Fedora bootc underneath, which means it keeps everything that already makes Bluefin nice to live with: it’s atomic, every codec is in place, updates happen quietly in the background, and you can always roll back if something breaks. What I changed is mostly in service of speed. Instead of the stock Fedora kernel it runs the CachyOS kernel with the BORE scheduler, re-signed with my own key so it still boots cleanly under Secure Boot, and the installer walks you through enrolling that key so you never have to turn Secure Boot off.
Around that there are a few things I’d always wished for. You can switch the sched_ext CPU schedulers live from a small GUI (scx_lavd when I’m gaming, plain BORE the rest of the time). There’s a little tool I wrote, Wayland Scroll Factor, for the touchpad scroll and pinch speed that GNOME stubbornly won’t expose, which matters a lot since the Framework 13 touchpad is unusably fast without it. GNOME comes set up for tiling out of the box with o-tiling, a fork of System76’s Pop Shell, plus Hyprland-style keybindings, and gaming is one command away with a native Steam/Proton stack, Bazzite-style. The whole image is built, tested and signed on CI, and the ISOs are distributed torrent-first through the Internet Archive.
I benchmarked the kernel honestly on the same laptop, a Framework 13 with a Ryzen 5 7640U, swapping only the ostree deployment between Margine OS and stock Bluefin DX: roughly 1.8x faster context-switch latency, +54% thread throughput, and 43 to 55% lower median scheduling latency, with a small cost at the worst-case tail, which is the expected BORE trade-off and honestly a sign the numbers aren’t cherry-picked. The full method and raw data are on the site.
It’s a personal, opinionated project with a single maintainer, so feedback and criticism are genuinely welcome. There’s also an experimental NVIDIA variant I can’t test myself, since I have no NVIDIA hardware, so if you run NVIDIA and feel like helping validate it, that would mean a lot.

“…resigned with my own key…”
That’s a “no” from me, dawg. This isnt a distro, this a later revision you could easily just target and run. I don’t think you know exactly what constitutes an entire distribution.
Well, you can call it a custom image if you feel “downstream image” isn’t the right term, but Margine is a downstream image in the same way that Bluefin and Bazzite are. Of course, I’m not claiming to have created a new Linux distribution from scratch.
Then what is? And which authorities endorses that view? Or…, is it perhaps possible to arrive at that definition by (logical) necessity? If no such authorities exist and if it doesn’t follow by necessity, then how is your definition anything but arbitrary?
Well, first off it’s all completely based around this one persons hardware and needs, using personal keys instead of those in the care of an organization.
There’s nothing wrong with making your own cool Linux is stitched together from the pieces you need.
It’s just something short of a distribution.
The op isn’t even doing the “distribution” component, their isos are just torrents hosted by the internet archive.
Which isn’t an insult, it’s a laudable achievement to put together an os, it just might fall short of a distribution.
Think about it like this: if you swapped the engine and drivetrain of a Silverado into an old jeep and replaced the body panels with those of a bronco carefully bent and shaped to fit the new geometry did you make a new model of car? No, of course not. It’s cool, and I want to see and drive it, but you didn’t make The Homer, you made a custom car.
If you started a business modifying other people’s jeeps with ls engine and blazer body swaps then do you have a new model of car? The many shops that do this in real life would like you to think so, but their creations remain legally registered as jeeps and no one except the dorkiest of owners refer to them as Homers.
