iso9660
iso9660 is program which formats a file system to the ISO 9660 stan-
dard. This allows the use of the Rock Ridge extensions, which contain
information about UNIX file names and permissions. A file system result-
ing from this program can be written to its own partition or file before it is
burned onto disk. Alternatively, depending on the hardware (see above), it
can be channelled directly to cdglow, whereupon the need for such a
large interim storage is avoided. In either scenario changes to the source
file system should be avoided while iso9660 is running and ensure that
the target file system does not share the same directory path of another
image produced by an earlier running of the program.
Typically, a Level 1 ISO 9660 file system is generated, in which the file
names are converted to conform to the standard 8.3 convention. A limita-
tion of this convention is that only capital letters, numbers and under-
scores can form such a file name. This is however necessary to provide a
file system which is almost universally accessible and readable.
iso9660 is not limited to this convention, however, and with appropriate
parameters certain extensions are permissable. This will of course have
the effect, that not all operating systems will be able to read the files, es-
pecially if iXOS-JUKEMAN is not installed on the operating system in
question. For this reason, it is advisable to carry out tests before burning
CD’s whose file systems exploit this feature.
ISO 9660-conforming parameters and options
rr
This parameter allows the Rock Ridge extensions to be added to areas
which are not occupied by ISO 9660. As a result, the image contains an
ISO 9660 file system with additional POSIX properties, which can then be
processed by file systems able to understand these rr extensions. The
added advantage of this system is that the source documents can be
named arbitrarily, as both the converted ISO 9660 names together with
the rr names now reside on the target disk.
joliet
Writes a disk in Joliet format (Unicode-support, long filenames).
isolevel2
Permits the use of file names up to 32 characters long, corresponding to
ISO 9660 Interchange Level 2. Level 1 allows only the 8.3 format for nor-
mal files.
