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

NAME

     mount_cd9660 -- mount an ISO-9660 filesystem

SYNOPSIS

     mount_cd9660 [-o options] special node

DESCRIPTION

     The mount_cd9660 command attaches the ISO-9660 filesystem residing on the device special to the global filesystem namespace at the location
     indicated by node.  Both special and node are converted to absolute paths before use.

     The options are as follows:

     -o      Options are specified with a -o flag followed by a comma separated string of options.  Besides options mentioned in mount(8) man
	     page, following cd9660-specific options are supported:

	     extatt  Enable the use of extended attributes.

	     gens    Do not strip version numbers on files and leave the case of the filename alone.  (By default, uppercase characters are trans-
		     lated to lowercase, and 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 giving a version number, in which case you get the last one, or by explicitly
		     stating a version number (albeit it's quite difficult to know it, if you are not using the gens option), in which case you
		     get the specified version.

	     nocasetrans
		     A synonym for nomaplcase.

	     nojoliet
		     Do not make use of Joliet extensions for long filenames which may be present in the filesystem.

		     Interpretation of Joliet extensions is enabled by default, Unicode file names are encoded into UTF-8.

	     nomaplcase
		     File names on cd9660 cdrom without Rock Ridge extension present should be uppercase only.	By default, cd9660 recodes file
		     names read from a non-Rock Ridge disk to all lowercase characters.  nomaplcase turns off this mapping.

	     norrip  Do not use any Rockridge extensions included in the filesystem.

	     nrr     Same as norrip.  For compatibility with Solaris only.

	     rrcaseins
		     Makes all lookups case-insensitive even for CD-ROMs with Rock-Ridge extensions (for Rock-Ridge, default is case-sensitive
		     lookup).

     For compatibility with previous releases, following obsolete flags are still recognized:

     -e      Same as -o extatt.

     -j      Same as -o nojoliet.

     -g      Same as -o gens.

     -r      Same as -o norrip.

HISTORY

     The mount_cd9660 utility first appeared 4.4BSD.  Support for Joliet filesystem appeared in NetBSD 1.4.  Options nomaplcase and rrcaseins were
     added in NetBSD 1.5.  UTF-8 encoding of Unicode file names for Joliet filesystems was added in NetBSD 3.0.

NOTES

     For Joliet filesystems, the Unicode file names used to be filtered to ISO-8859-1 character set.  This changed in NetBSD 3.0, file names are
     encoded into UTF-8 now by default.  The behaviour is controllable by the vfs.cd9660.utf8_joliet sysctl; the former behaviour is available by
     setting it to 0.

BUGS

     For some cdroms the information in the Rock Ridge extension is wrong and the cdrom needs to be mounted with "norrip".  A sign that something
     is wrong is that the stat(2) system call returns EBADF causing, e.g., "ls -l" to fail with "Bad file descriptor".

     The cd9660 filesystem does not support the original "High Sierra" ("CDROM001") format.

     POSIX device node mapping is currently not supported.

     Version numbers are not stripped if Rockridge extensions are in use.  In this case, you have to use the original name of the file as recorded
     on disk, i.e. use uppercase and append the version number to the file.

     There is no ECMA support.
