Yes, we need to get some notification that media is changed and then trigger geom action. Right now there is no notification from hardware in most cases and there is no support for handling that in drivers, AFAIK. Maybe ahci driver starts to add support for that. So either something needs to poll media for changes or a user has to trigger some action explicitly. No magic. -- Andriy Gapon
