Nice idea! How does this actually work? I'm guessing it's wrapping a custom loader + docker + the image into an executable binary - or something like that?

  Sounds like universal appimage

  Yep pretty much. The executables bundle crun (a container runtime)[0], and a fuse implementation of squashfs and overlayfs. Appended to that is a squashfs of the image. At runtime the squashfs and overlayfs are mounted and the container is started. [0]: https://github.com/containers/crun https://github.com/containers/crun

    Apologies for my ignorance, but how does squashfs fit into this picture? It seems I'm missing some pieces of the puzzle.

      Ok, I've checked code a bit. We use squashfs to pack/unpack OCI Bundle, and for lower layer in OverlayFS.
