> Some mount options are never passed to the kernel, and thus can't appear > in /proc/mounts. Examples include user, users, and _netdev for NFS. These options control *who* may mount and *when* to mount. They are not a property of the mount itself and are not added to /etc/mtab. There's a "user=ID" option that is added to /etc/mtab in case of user mounts. This identifies the owner of the mount, so that it can be unmounted by that user. There are patches in -mm that enable the kernel to store this info. Do you have other examples in mind?
