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

     mount_cd9660 -- mount an ISO-9660 file system

     mount_cd9660 [-o options] special node

     The mount_cd9660 command attaches the ISO-9660 file system residing on
     the device special to the global file system 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 sepa-
             rated 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 ver-
                     sion 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.

                     A synonym for nomaplcase.

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

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

                     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 file

             nrr     Same as norrip.  For compatibility with Solaris only.

                     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.

     mount(2), unmount(2), fstab(5), mount(8), mscdlabel(8)

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

     For Joliet file systems, 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 set-
     ting it to 0.

     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 file system 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.
