MOUNT_CD9660(8)		FreeBSD	System Manager's Manual	       MOUNT_CD9660(8)

     mount_cd9660 -- mount an ISO-9660 file system

     mount_cd9660 [-begjrv] [-C	charset] [-o options] [-s startsector] special

     The mount_cd9660 utility attaches the ISO-9660 file system	residing on
     the device	special	to the global file system namespace at the location
     indicated by node.	 This command is normally executed by mount(8) at boot

     The options are as	follows:

     -b	     Relax checking for	Supplementary Volume Descriptor	Flags field
	     which is set to a wrong value on some Joliet formatted disks.

     -e	     Enable the	use of extended	attributes.

     -g	     Do	not strip version numbers on files.  (By default, if there are
	     files with	different version numbers on the disk, only the	last
	     one will be listed.)  In either case, files may be	opened without
	     explicitly	stating	a version number.

     -j	     Do	not use	any Joliet extensions included in the file system.

     -o	     Options are specified with	a -o flag followed by a	comma sepa-
	     rated string of options.  See the mount(8)	man page for possible
	     options and their meanings.  The following	cd9660 specific	op-
	     tions are available:

	     extatt	   Same	as -e.
	     gens	   Same	as -g.
	     nojoliet	   Same	as -j.
	     norrip	   Same	as -r.
	     brokenjoliet  Same	as -b.

     -r	     Do	not use	any Rockridge extensions included in the file system.

     -s	startsector
	     Start the file system at startsector.  Normally, if the underly-
	     ing device	is a CD-ROM drive, mount_cd9660	will try to figure out
	     the last track from the CD-ROM containing data, and start the
	     file system there.	 If the	device is not a	CD-ROM,	or the table
	     of	contents cannot	be examined, the file system will be started
	     at	sector 0.  This	option can be used to override the behaviour.
	     Note that startsector is measured in CD-ROM blocks, with 2048
	     bytes each.  This is the same as for example the info command of
	     cdcontrol(1) is printing.	It is possible to mount	an arbitrary
	     session of	a multi-session	CD by specifying the correct
	     startsector here.

     -C	charset
	     Specify local charset to convert Unicode file names when using
	     Joliet extensions.

     -v	     Be	verbose	about the starting sector decisions made.

     The following command can be used to mount	a Kodak	Photo-CD:

	   mount_cd9660	-o rw -v -s 0 /dev/cd0 /cdrom

     cdcontrol(1), mount(2), unmount(2), cd9660(5), fstab(5), mount(8)

     The mount_cd9660 utility first appeared in	4.4BSD.

     The Unicode conversion routine was	added by Ryuichiro Imura
     <> in 2003.

     POSIX device node mapping is currently not	supported.

     Version numbers are not stripped if Rockridge extensions are in use.  In
     this case,	accessing files	that do	not have Rockridge names without ver-
     sion numbers gets the one with the	lowest version number and not the one
     with the highest.

     There is no ECMA support.
