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.
