> I intend to have the update model of ChromeOS (two partition scheme, reboot to update), but Void being a rolling release only distribution may bring me same pains as Alpine edge brings to postmarketOS. You're kind of reinventing NixOS, but worse (NixOS has atomic upgrades and allows you to return to any generation of your system, not only the last one).

No, I'm reinventing ChromeOS. I started on this project with my father in mind, to make it easier for me to maintain his computer. My father would not run NixOS, but maybe I'm wrong. This will give a single image and very little tooling outside of end user parts. It probably will be much simpler. If totally seamless and _automatic_ updates can be achieved with NixOS I'm all ears.

  The point of the ChromeOS dual-partition scheme is that ChromeOS system installs are read-only and immutable - they're the equivalent to creating a squashfs live system and burning it to a fresh CD, so it wouldn't make sense to de-duplicate data among them. If you don't care about this property and need more flexibility than that anyway (as with the average Linux distribution, which is updating stuff in /usr all the time), snapshots are the sensible choice and the dual-partition scheme is quite pointless.

    I think fedora-silverblue is aiming for some sort of middle ground. It would be interesting to see how it plays out.

  Put whatever update command (nixos-rebuild switch --upgrade I believe? haven't touched nixos in a while) in a crontab and you get automatic updates. If the update fucked it up, you can boot back into the previous configuration. In this way, it's really, really hard to brick a NixOS install. That's the beauty of it. Of course, it's not going to be as transparent as ChromeOS: If the update failed, you'll have to manually select the previous configuration in the GRUB menu. That's definitely something solvable with a bit of code though. So, yes, automatic and seamless updates can be achieved with NixOS, given a bit of configuration and maybe a bit of code. Whether it's the right approach for your use-case remains an open question though. NixOS has many other rough edges (many applications don't "just work" on it) which might make it a deal-breaker, depending on your use-case. But you might want to look into its update models, you might get some good ideas :).

Just add the following to your /etc/nixos/configuration.nix file: system.autoUpgrade = { enable = true; dates = "daily"; };

  For desktop Linux I'd recommend https://getsol.us https://getsol.us, for everything else I'd use NixOS.
