Adding a new compressor must be careful done because it changes the core of handling an image. -More efficient delta updates -============================ - -A whole update could be very traffic intensive. Specially in case -of low-bandwidth connections, it could be interesting to introduce -a way for delta binary updates. -There was already several discussions on the Mailing List about -this. If introducing binary delta is high desired, on the other side -it is strictly required to not reduce the reliability of the update -and the feature should not introduce leaks and make the system -more vulnerable. It is accepted that different technologies could be added, -each of them solves a specific use case for a delta update. - -SWUpdate is already able to perform delta updates based on librsync library. This is -currently a good compromise to reduce complexity. Anyway, this helps in case of -small changes, and it is not a general solution between two generic releases. -A general approach could be to integrate SWUpdate with a storage to allow one -a delta upgrade from any release. - Support for OpenWRT ===================
