Many people including me are annoyed by supermount attempting to mount empty drives. It is causing delays in GUI filemanagers; it also makes zsh completion really slow (just try to complete insode /mnt).
Currently there is no check for drive change in subfs_go_online. We check for subfs_needs_mount which is something different. Do we get media change from device when we insert new media? In this case we could _try_ to insert check for media change into subfs_go_online and simply fall out if no media has been inserted. I am going to try it @home anyway, but - comments? -andrej
