NAME
     mountudfs - mount a udfs file system

SYNOPSIS
     mount -F udfs [genericoptions] [-o specificoptions]
          [-O] special mountpoint


     mount -F udfs [genericoptions] [-o specificoptions]
          [-O] special  mountpoint


DESCRIPTION
     The mount utility attaches a udfs file system  to  the  file
     system  hierarchy  at the mountpoint, which is the pathname
     of a directory. If mountpoint 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  mountpoint  as
     the  only  arguments,  mount searches /etc/vfstab to fill in
     the missing arguments, including the  specificoptions.  See
     mount(1M).


     The udfs file system supports direct mounting of files  con-
     taining  the  file  system  as  well  as  block devices. See
     mount(1M) and lofiadm(1M).


     If  special  and  mountpoint  are  specified  without   any
     specificoptions, 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.

OPTIONS
     See mount(1M) for the list of supported genericoptions.


     The following options are supported:

     -o specificoptions

         Specify udfs file system specific options  in  a  comma-
         separated list with no intervening spaces. The following
         specificoptions 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 sys-
         tem inaccessible. If a mount  is  attempted  on  a  pre-
         existing  mount  point  without  setting  this flag, the
         mount fails, producing the error device busy.

     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.

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
