mobile-nixos VS nixwrt

For now, only information about Ubuntu Touch support is available on our website. We plan to extend that to PostmarketOS and NixOS. But which devices does Ubuntu Touch support? For example those:

Github has more recent activity: https://github.com/NixOS/mobile-nixos

NixOS/mobile-nixos

Any nixos users here? Anyone have any luck running mobile nixos?

samueldr has been doing a lot of work in that direction. See https://mobile.nixos.org/

With the code from https://github.com/NixOS/mobile-nixos/pull/445, build the demo example with nix-build --argstr device pine64-pinephonepro -A outputs.temp-tow-boot-install-script examples/demo/; of course instead of example/demo you can have your own configuration, but I started with demo

https://github.com/NixOS/mobile-nixos/pull/361

Though you might want to ask around for your particular use case. While basic support (it boots) is right around the corner, it's probably not yet at a point where it'll be nice to use.

As for what I did with those zip files? I made the equivalent for another Linux on Android devices distro. The implementation probably won't suit your tastes, but it's something else to look at to figure out what can be done.

tl;dr: here are three commercial embedded NixOS uses and a couple of other embedded NixOS projects

1. LumiGuide uses NixOS for their embedded systems, which track automatic bicycle rentals at little solar-powered stations IIRC: https://av.tib.eu/media/39625 (also some coverage here: https://www.worksonarm.com/blog/nixos/ )

2. Yakkertech uses NixOS for their embedded systems, which do baseball pitch tracking: https://av.tib.eu/media/50713

3. Swift Navigation uses NixOS for CI/CD for the embedded systems they use for GPS and navigation: https://blog.swiftnav.com/using-nixos-to-manage-hardware-tes...

I'd only heard of the first two, and discover the third just now.

There are also two downstream distros/related projects that target embedded systems, but idk how much commercial use they've yet seen, if any:

a. https://github.com/telent/nixwrt

b. https://github.com/cleverca22/not-os

You might want to check out https://github.com/telent/nixwrt and https://github.com/cleverca22/not-os as solutions with similar goals. The former is a promising but yet-unfinished way of using Nix to manage a router, while the latter is a similar way of using Nix to generate an immutable OS image.

And, if you take into consideration my personal, subjective opinions on what a distro must be (declarative, fearless to tinker with, mostly binary based but with easy overrides, mostly stateless, easy to roll back in case something goes wrong), then that leaves pretty much two options: NixOS and Guix, and because I don't really like LISP syntax, I go with NixOS as my favourite distro for desktops and servers. For embedded, I've recently tried NixWrt and it seems to work quite well, however I'm still using OpenWRT for "mission-critical" routers.
