Encyclopedia articles need to be written from a neutral point of view, and should refer to a range of independent, reliable, published sources, not just to materials produced by the creator of the subject being discussed. This is important so that the article can meet Wikipedia's verifiability policy and the notability of the subject can be established. If you still feel that this subject is worthy of inclusion in Wikipedia, please rewrite your submission to comply with these policies.

Comment: Also needs additional context. I still have no clue what this is after reading the article. Make sure that non-experts and folks not familiar with computers can still understand it. Captain Eek Edits Ho Cap'n!⚓ 21:12, 22 October 2019 (UTC)

RAUC (Robust Auto-Update Controller) is an open source OTA update framework for embedded or IoT devices running a Linux operating sytsem.[2][3]
The main purpose of RAUC is to provide cryptographically verified, fail-safe firmware updates for Linux systems with a redundant (A/B) system partition set.
RAUC serves both as a host and a target tool. The host tool allows the creation of signed (and optionally encrypted) update artifacts (called 'bundles') typically consisting of the file system image(s) to install and additional metadata. The target tool runs as a service on the embedded device and handles the bundle verification and installation.
Design and principles
editCryptographic verification of OTA updates is seen as mandatory and can thus not be deactivated. RAUC uses standard X.509 cryptography for this.
While RAUC performs mainly full image-based updates, it also comes with support for unpacking tar archives.
The partition layout for RAUC is described in a target system configuration file. The RAUC update service running on the target uses this information to automatically determines the inactive system partitions that can serve as installation targets.
Features
editD-Bus API
editA D-Bus API allows integrating RAUC into custom applications that can trigger installation, show progress or introspect system status.
Bootloader Interaction
editTo switch from the running system copy to the updated copy, RAUC needs to interact with the system's bootloader.
The currently supported bootloaders are Barebox, GRUB, UEFI, U-Boot, or custom implementations.
HTTP(S) Bundle Streaming
editSince v1.7 RAUC has built-in support for streaming update bundles from a web server via HTTP range requests. This allows updating a device without the need for intermediate on-target storage.
Adaptive (Delta-like) Updates
editIn OTA update scenarios, bandwidth is often limited. Adaptive updates are a generic mechanism for delta-like download optimizations.
Encrpytion
editBuild System Integration
editRAUC support is available or integrated into common embedded Linux build systems like Yocto Project/ObenEmbedded[4], Buildroot[5], or PTXdist. As a host tool, it is also part of common Linux distributions such as Debian[6], Ubuntu, Arch Linux or NixOS.
Reception And Usage
edit- The SteamOS on the Valve Steam Deck is updated using RAUC[7][8]
- Deutsche Bahn Intercity Express (ICE) train info terminals are updated using RAUC[9]
