UDF / Packet writing support

Post by Steven D. Lear » Tue, 19 Jun 2001 00:28:26



Hello,

I unerstand that there is a Linux development group that is working on
UDF/Packet Writing support, and was wondering if anyone has tried to compile
this under FreeBSD yet?

If so, how well does it work? Is it stable, or to be more precise, more
stable than DirectCD under Win2K?

Thanks
Steven D. Leary

What's the name of this project?

I would love to have some sort of support added to "mount" that supports
UDF/packet writing, so that you can (for the most part) R/W to a CD-RW
like a regular floppy.  Well, not totally.  It could be something like
"mount_udf".  I've had troubles with mkisofs not storing the entire
pathnames of directories, e.g., I see stuff like bin usr.sbin instead of
/usr/src/bin, /usr/src/usr.sbin.

This UDF/packet writing support is something that is sorely needed.

Yes, there is a packet writing project on SourceForge
(http://sourceforge.net/projects/packet-cd) and it works more or less under
kernel 2.4.5. There has been some UDF support in the kernel for some time
(at least since 2.2.18). I use Linux so I don't know about BSD patches but
I'm thinking of switching over to BSD and would like any info RE ports.

1. Mounting DirectCD 3.0 Media (ISO 9660/UDF) / UDF write support

Hi

Does anybody know whether it's possible to mount a DirectCD 3.0 medium
on Linux and if yes, how? A DirectCD 3.0 medium contains a single
session with a single track but two filesystems. An ISO 9660 fs that
contains an UDF reader for Win32 and an UDF fs with actual data. If I
mount such a CD on Linux I see the ISO fs only, which is completely
useless. On Windows you can see the ISO filesystem only when there's no
UDF reader installed. As soon as you install the UDF reader on the ISO
fs, you can see the UDF fs but no longer the ISO fs. Other CD Writer
applications like Nero correctly detect two filesystems on such a
medium, so I assume this is some standard. I use Kernel version 2.2.17
and UDF version 0.9.2.1.

Do the kernel versions 2.4.x support writing to a mounted CD-RW with UDF

(like DirectCD on Windows)? The documentation of the UDF driver says
that this is not possible for 2.2.x versions because of a kernel
limitation. I can of course write to a UDF fs using a loop device and
then burn the image on a CD-RW. But this way I loose the advantages of
UDF.

Thanks in advance
