It makes a lot of sense to have one event > supported by all devices. But don't ask me which one would be the best.. Users typically have site-specific udev rules or similar. There is no standard entity handling these events. Sadly. I'm all for standardizing on RESIZE=1. However, we can't really get rid of the emitting existing SDEV* event without breaking existing setups. -- Martin K.
