.Sh BUGS
The cd9660 filesystem 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, accessing files that don't have Rockridge names without
version numbers gets the one with the lowest version number and not
the one with the highest.
.Pp
There is no ECMA support.
.Sh HISTORY
The
.Nm mount_cd9660
utility first appeared 4.4BSD.
