To be more precise, when wanting to unmount while not having superuser permissions, and there is no uhelper=somethingvalid marker in the mtab file, then the filesystem has to be in /etc/fstab with the option 'users' (and no marker needs to be present in mtab, and even if it is, it will be ignored), or the /etc/fstab file contains the option 'user' and the /etc/mtab file contains 'user=yourname'.
