Fixed. Thanks! So how does umount determine that a device was mounted by a user and thus that the user is alllowed to unmount it again? In my /proc/mounts there is no indication that a user mounted a partition (apart from the "nosuid,nodev,noexec" hint, but that is no guarantee). Does it require a certain minimum kernel version? And what if the mount option is "users"? And in both cases, what if root mounted such a partition? How does umount figure out that a user may still not unmount it?
