I know you can build a Debian system with debootstrap. Using debootstrap it should be possible to create a custom image. The main partition could be read only with separate mounts for anything that need to be read write.

Using containers it should be possible to create a filesystem image. I think the tricky part it testing the image and then updating the existing partition. Maybe some custom ostree tool could do the trick. If not there is always rsync and btrfs snapshots.

    Well, uBlue can be as light as you want it to be.

    Some other projects I’m thinking of:

    • VanillaOS (Debian based)
    • NixOS
    • Fedora CoreOS
    • uCore (based on CoreOS)
    • openSUSE MicroOS
    • EndlessOS (Debian based)
    • blendOS

    Is it for a personal computer or a server?
