I make the specification of non-linux because otherwise this would just become a thread full of obscure distros that do the same thing as a million other distros.

Some lesser known OSs:

  • AROS - based on Amiga OS, has some derivatives like IcarOS and MorphOS
  • Haiku - based on BeOS
  • Redox - Unix-like, made in Rust (might technically count as linux?)
  • Serenity - Unix-like, very late 90s look and feel
  • Kolibri - Tiny OS, the image is ~44MB. It also has a smaller version that fits in a single floppy.
  • PhantomOS - When 3 Russians decide to turn everything about a typical OS upside down.
  •  CanadaPlus   ( @CanadaPlus@lemmy.sdf.org )

    Nobody’s mentioned Guix. It’s a GNU project, which is like Nix, but has a number of novel features. I’ll copy in from my own thread about it:

    Based on what I’ve heard so far: GNU Shepard instead of systemd, a package manager that compiles things from source and allows user-defined compiler options, a totally different way of arranging system files, and Guile-Scheme is used for everything; it sounds like there’s no other kind of configuration anywhere.

    It’s planned to be Hurd compatible, so I’d argue it counts.
