We use TorizonOS, which is also based on OSTree: https://www.torizon.io/blog/ota-best-linux-os-image-update-m....

It works quite well for our edge devices. It’s tightly integrated with Toradex hardware, but not limited to it.

It may seems litte a niche, but it has strong potential for long‑term supported edge products. Any additional experiences to share?
