Options and parameters which do not conform to ISO 9660
It must be emphasized that the use of the following options will lead to
ISO 9660 images which will not be fully readable by all operating systems.
longnames
Permits the use of long file names.
nicenames
Allows any character to be used to construct the file name. However, it is
better to use the option allow=<charlist> (see below).
noversion
Suppresses the version number.
dir.ext
Permits the use of '.xxx' extensions to directory names.
omit.
Suppresses the trailing period ( . ) of ISO 9660 file names.
.by_
Replaces leading periods ( . ) with underscores ( _ ).
allow=<charlist>
By default, standard ISO 9660 permits only the use of capital letters,
numbers, periods and underscores. Small letters must therefore be capi-
talized and any characters which are not allowed are converted to the un-
derscore.’_’.
This option allows you to extend the list of characters which can appear in
the resultant image. An example is allow=-~ which allows bothof these
characters to appear infile names. By using allow=all or allow=ALL it
is possible to prevent any conversion from taking place. This should not
be confused with the option nicenames; which has a more extensive ef-
fect as it ignores a number of ISO 9660 conventions, e.g., the version
number. For this reason it is preferable to use allow=all instead of ni-
cenames.
