That might have been too strong. Never having worked with e3 and after decades of building IOCs statically and (carefully) dynamically, I still don't trust on-demand loading at start-up time. I know that the e3 reliability numbers are excellent, so maybe it's an assumed risk or German angst.
Might be a misunderstanding. That's all part of the by-instance configuration, which is outside of the container. In the distant past, VME IOCs were adding the drivers for all hardware used at an installation into a single binary. Having just one (VxWorks) image for all IOCs removes a lot of complexity. The world was simpler back then... IMHO, the killer is the added code. VxWorks images were loadable objects with run-time linking: you could load and unload state machines etc. at any time on the instance - despite using a single image. (Some spectacular crashes may have contributed to my run-time linking concerns.) Cheers, ~Ralph
