108 Normally, if the underlying device is a CD-ROM drive,
110 will try to figure out the last track from the CD-ROM containing
111 data, and start the filesystem there. If the device is not a CD-ROM,
112 or the table of contents cannot be examined, the filesystem will be
113 started at sector 0. This option can be used to override the behaviour.

140 POSIX device node mapping is currently not supported.
142 Version numbers are not stripped if Rockridge extensions are in use.
143 In this case, accessing files that don't have Rockridge names without
144 version numbers gets the one with the lowest version number and not
145 the one with the highest.
147 There is no ECMA support.
