NetBSD 6.1.5 - man page for mount_cd9660 (netbsd section 8)

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 translated 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 exten-
		     sions (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 be-
     haviour is controllable by the vfs.cd9660.utf8_joliet sysctl; the former behaviour is avail-
     able 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.
