NAME

       mount_udfs - mount a udfs file system

SYNOPSIS

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

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

DESCRIPTION

       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 sym-
       bolic link refers, rather than on top of the symbolic link itself.

OPTIONS

       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  spe-
			       cific_options are available:

			       m

				   Mount the file system without making an entry in /etc/mnttab.

			       remount

				   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 system is not
				   currently mounted.

       -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.

DIAGNOSTICS

       not super user

	   The command is run by a non-root user. Run as root.

       no such device

	   The device name specified does not exist.

       not a directory

	   The specified mount point is not a directory.

       is not an udfs file system

	   The device specified does not contain a udf 1.50 file system or the udfs file system module is not available.

       is already mounted

	   The specified device is already in use.

       not a block device

	   The device specified is not a block device. Use block device to mount.

       write-protected

	   The device is read-only.

       is corrupted. needs checking

	   The file system is in an inconsistent state. Run fsck.

NOTES

       Copy-protected files can be stored on DVD-ROM media using Universal Disk Format (UDF). Reading these copy-protected files is  not  possible
       as  this  involves  an  authentication process. Unless an authentication process between the host and the drive is completed, reading these
       copy-protected files after mounting and before the authentication process, returns an error.
