Both .Ar special and .Ar node are converted to absolute paths before use. .Pp The options are as follows: .Bl -tag -width indent .It Fl o Options are specified with a .Fl o flag followed by a comma separated string of options. Besides options mentioned in .Xr mount 8 man page, following cd9660-specific options are supported: .Bl -tag -width indent .It Cm extatt Enable the use of extended attributes. .It Cm 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.) .Pp 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 .Cm gens option), in which case you get the specified version. .It Cm nocasetrans A synonym for .Cm nomaplcase . .It Cm nojoliet Do not make use of Joliet extensions for long filenames which may be present in the file system. .Pp Interpretation of Joliet extensions is enabled by default, Unicode file names are encoded into UTF-8. .It Cm 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. .Cm nomaplcase turns off this mapping. .It Cm norrip Do not use any Rockridge extensions included in the file system. .It Cm nrr Same as .Cm norrip . For compatibility with Solaris only. .It Cm rrcaseins Makes all lookups case-insensitive even for CD-ROMs with Rock-Ridge extensions (for Rock-Ridge, default is case-sensitive lookup). .El .El .Pp For compatibility with previous releases, following obsolete flags are still recognized: .Bl -tag -width indent .It Fl e Same as .Fl o .Cm extatt . .It Fl j Same as .Fl o .Cm nojoliet . .It Fl g Same as .Fl o .Cm gens . .It Fl r Same as .Fl o .Cm norrip . .El .Sh SEE ALSO .Xr mount 2 , .Xr unmount 2 , .Xr fstab 5 , .Xr mount 8 , .Xr mscdlabel 8 , .Xr vndconfig 8 .Sh HISTORY The .Nm utility first appeared .Bx 4.4 . Support for Joliet file system appeared in .Nx 1.4 . Options .Cm nomaplcase and .Cm rrcaseins were added in .Nx 1.5 . UTF-8 encoding of Unicode file names for Joliet file systems was added in .Nx 3.0 . .Sh NOTES For Joliet file systems, the Unicode file names used to be filtered to ISO-8859-1 character set. This changed in .Nx 3.0 , file names are encoded into UTF-8 now by default. The behaviour is controllable by the .Em vfs.cd9660.utf8_joliet sysctl; the former behaviour is available by setting it to 0. .Sh 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 .Xr stat 2 system call returns .Er EBADF causing, e.g., "ls -l" to fail with "Bad file descriptor". .Pp The cd9660 file system does not support the original "High Sierra" ("CDROM001") format. .Pp POSIX device node mapping is currently not supported. .Pp 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. .Pp There is no ECMA support.
