mount_udfs(1M)

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 symbolic 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 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
                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.

          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.

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 avail-
           able.

     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.
