mount_udfs - mount a udfs file system


mount -F udfs [ generic_options ] [ -o specific_options ] [ -O ] special mount_point mount -F udfs [ generic_options ] [ -o specific_options ] [ -O ] special | mount_point


The mount utility attaches a udfs file system to the file system hierarchy at the mount_point, which is the pathname of a directory. If mount_point has any contents prior to the mount operation, these are hidden until the file system is unmounted. If mount is invoked with either special or mount_point as the only arguments, mount searches /etc/vfstab to fill in the missing arguments, including the specific_options. See mount(1M). If special and mount_point are specified without any specific_options, the default is rw. If the directory on which a file system is to be mounted is a symbolic link, the file system is mounted on the directory to which the symbolic link refers, rather than on top of the symbolic link itself.


See mount(1M) for the list of supported generic_options. The following options are supported: -o specific_options Specify udfs file system specific options in a comma-separated list with no intervening spaces. The following specific_options are available: m Mount the file system without making an entry in /etc/mnttab. nosuid Mount the file system with setuid execution disallowed. You can also use nosuid to disallow setuid when mounting devices. By default, the file system is mounted with setuid execution allowed. remount SunOS 5.8 Last change: 11 Jun 1999 1 Maintenance Commands mount_udfs(1M) Remount the file system as read-write. The option is used in conjunction with the rw option. A file system mounted read-only can be remounted as read-write. This option fails if the file sys- tem is not currently mounted or if the file sys- tem is mounted as rw. rw | ro Read-write (rw) or read-only (ro). rw is the default. -O Overlay mount. Allow the file system to be mounted over an existing mount point, making the underlying file system inaccessible. If a mount is attempted on a pre-existing mount point without setting this flag, the mount fails, producing the error device busy.

Copy-protected files can be stored on DVD-ROM media using UDF. Reading these copy-protected files is not possible as this involves an authentication process. Unless an authen- tication process between the host and the drive is com- pleted, reading these copy-protected files after mounting and before the authentication process, returns an error.
