mount(8cdfs)							  mount(8cdfs)

Name
       mount,  umount  -  mount	 and  unmount  a ISO 9660 (CD-ROM) File System
       (CDFS)

Syntax
       /etc/mount -t cdfs [ -r -o options ] device directory

       /etc/umount [ -v ] directory

Description
       The command allows you to mount an ISO 9660 or High Sierra  (HSG)  for‐
       matted  file  system onto a directory.  Once a file system or directory
       has been mounted, it is treated as a file system.

       The argument device must refer to a block special file.

       The file directory must exist and must be a directory.  It becomes  the
       name of the newly mounted file system.

       General users can mount file systems with certain restrictions in addi‐
       tion to those listed in

       The command unmounts the file system that was previously mounted on the
       specified directory.

Options
       -r	   Indicates  that the file system is to be mounted read only.
		   Please note this is a mandatory option, and is appended  to
		   the mount string if not present.

       -v	   Tells what did or did not happen.  (Verbose flag)

       -o options  Specifies  options  as  a sequence of comma-separated words
		   from the list below.	 The defaults are:
		   ro,defperm,pgthresh=64
		   The CDFS options are:

       defperm	     Files and directories recorded on an ISO  9660  formatted
		     file  system  may	or  may not have permission bits. This
		     options ignores these permissions bits, if	 present,  and
		     defaults  all file and directory permissions to the value
		     0666, with a zero UID (owned by root). This is a  default
		     option  since the permissions on most of the existing ISO
		     9660 formatted CD-ROM's do not map into  the  UID	scheme
		     ULTRIX uses.

       nodefperm     Use the on-disk permission bits, if present. If a file or
		     directory is not recorded with permissions bits, the 0666
		     default is used.

       noversion     If	 a  file recorded on an ISO 9660 formatted file system
		     contains a version string, strip off the ';#'  extension.
		     Files and directory names are displayed in lowercase let‐
		     ters and name matching is performed in a case-insensitive
		     manner.   This  option should be used in conjunction with
		     mounting a CD-ROM containing MS-DOS applications.

       The option for is:

       -v     Tells what did or did not happen.	 (Verbose flag)

Restrictions
       If mounting of an ISO 9660 or HSG volume fails with
       cdfs_mount: Operation Not Supported
       refer to the reference  page for details pertaining to the correct sys‐
       tem  configuration  file	 options  which	 must exist prior to using the
       CDFS.

       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 being mounted on  top  of  the	symbolic  link
       itself.

Examples
       The command invokes to do its work.  A sample command is:
       # mount -t cdfs -o pgthresh=100 /dev/rz3c /cdrom
       To  mount  the  ISO 9660 formatted file system on the block device onto
       the local directory with the file version strings stripped, type:
       # mount -t cdfs -o noversion /dev/rz3c /cdfs
