65 .Nd mount an ISO-9660 filesystem
73 command attaches the ISO-9660 filesystem residing on the device
75 to the global filesystem namespace at the location indicated by
81 are converted to absolute paths before use.
83 The options are as follows:
84 .Bl -tag -width indent
86 Options are specified with a
88 flag followed by a comma separated string of options.
89 Besides options mentioned in
91 man page, following cd9660-specific options are supported:
92 .Bl -tag -width indent
94 Enable the use of extended attributes.
96 Do not strip version numbers on files and leave the case of the filename
98 (By default, uppercase characters are translated to lowercase,
99 and if there are files with different version numbers on the disk,
100 only the last one will be listed.)
102 In either case, files may be opened without giving a
103 version number, in which case you get the last one, or by explicitly
104 stating a version number (albeit it's quite difficult to know it, if
105 you are not using the
107 option), in which case you get the specified version.
112 Do not make use of Joliet extensions for long filenames which
113 may be present in the filesystem.
115 Interpretation of Joliet extensions is enabled by default, Unicode
116 file names are encoded into UTF-8.
118 File names on cd9660 cdrom without Rock Ridge extension present
119 should be uppercase only.
120 By default, cd9660 recodes file
121 names read from a non-Rock Ridge disk to all lowercase characters.
123 turns off this mapping.
125 Do not use any Rockridge extensions included in the filesystem.
129 For compatibility with Solaris only.
131 Makes all lookups case-insensitive even for CD-ROMs with Rock-Ridge
132 extensions (for Rock-Ridge, default is case-sensitive lookup).
136 For compatibility with previous releases, following obsolete flags are
138 .Bl -tag -width indent
165 utility first appeared
167 Support for Joliet filesystem appeared in
175 UTF-8 encoding of Unicode file names for Joliet filesystems was added in
178 For Joliet filesystems, the Unicode file names used to be filtered
179 to ISO-8859-1 character set.
182 file names are encoded into UTF-8 now by default.
183 The behaviour is controllable by the
184 .Em vfs.cd9660.utf8_joliet
185 sysctl; the former behaviour is available by setting it to 0.
187 For some cdroms the information in the Rock Ridge extension is wrong
188 and the cdrom needs to be mounted with "norrip".
189 A sign that something is wrong is that the
193 causing, e.g., "ls -l" to fail with "Bad file descriptor".
195 The cd9660 filesystem does not support the original "High Sierra"
198 POSIX device node mapping is currently not supported.
200 Version numbers are not stripped if Rockridge extensions are in use.
201 In this case, you have to use the original name of the file as recorded
202 on disk, i.e. use uppercase and append the version number to the file.
204 There is no ECMA support.
