60 The options are as follows:

63 Relax checking for Supplementary Volume Descriptor Flags field
64 which is set to a wrong value on some Joliet formatted disks.
66 Enable the use of extended attributes.
68 Do not strip version numbers on files.
69 (By default, if there are files with different version numbers on the disk,
70 only the last one will be listed.)
71 In either case, files may be opened without explicitly stating a

82 The following cd9660 specific options are available:

106 Normally, if the underlying device is a CD-ROM drive,
108 will try to figure out the last track from the CD-ROM containing
109 data, and start the file system there.
110 If the device is not a CD-ROM,
111 or the table of contents cannot be examined, the file system will be
113 This option can be used to override the behaviour.

123 It is possible to mount an arbitrary session of a multi-session CD by specifying
130 to convert Unicode file names when using Joliet extensions.
132 Be verbose about the starting sector decisions made.
135 The following command can be used to mount a Kodak Photo-CD:

150 POSIX device node mapping is currently not supported.
152 Version numbers are not stripped if Rockridge extensions are in use.
153 In this case, accessing files that do not have Rockridge names without
154 version numbers gets the one with the lowest version number and not
155 the one with the highest.
157 There is no ECMA support.
