     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

     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

     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 fol-
                             lowing  specific_options  are avail-


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


                                 Remount  the  file   system   as
                                 read-write.  The  option is used
                                 in  conjunction  with   the   rw

                                 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.

     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.


         The device is read-only.

     is corrupted. needs checking

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


     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.
