Should we include OpenHAB 2 on the new emonSD image?

I wouldn’t expect that image to progress any further and you may find yourself in a minority group regarding bugs and support etc, The older images are fully supported and (apparently) the next version will be significantly different to the existing images, so that would suggest the end of the road for the 13Jun18 beta image. If you need an image immediately, IMO you should use the older image for now.

See the Mosquitto won't start on boot after raspbian and emonsd update thread (among others) NOT using rc.local is a longstanding point of discussion, although specific details about the next image have not been openly discussed in any detail, Glyn has stated that although the next image will not be RO it will still have the log files in RAM, so we do not yet know if the rc.local stuff has been dropped yet and/or how the logfiles are going to be managed.
