The udftools package contains utilities for creating and mounting CD-RW disks with udf filesystems for both reading and writing.  Udf filesystems are used on both CD-RW media and on DVD.  For more details of the udf filesystem standard see:  http://www.osta.org and http://www.ecma.org

[Note: these instructions have only been tested for CD-RW media]

The kernels in 2.4 series include the drivers for reading udf filesystems on CD-RW media, but packet-writing is not fully functional, so a patch must be installed on the kernel to update the packet-writing subsystem.  The patch for linux-2.4.20 can be downloaded from: http://w1.894.telia.com/~u89404340/patches/packet/2.4/packet-2.4.20.patch.bz2

Installation of the kernel patch

Download and unpack the patch, and change to the kernel source directory to patch the kernel with the following command:

patch -Np1 -i packet-2.4.20.patch

In the kernel configuration, check your settings with those listed here:

Block devices
	Packet writing on CD/DVD media:		Y or M
File Systems
	UDF file systems support (read only)	Y
	UDF write support (DANGEROUs)		Y

Now recompile the kernel

make dep &&
make bzImage&&
make modules &&
make modules_install

Copy /usr/src/linux/arch/i386/boot/bzImage and /usr/src/linux/System.map to /boot, edit /etc/lilo.conf appropriately and run lilo.
If you build the packet writer as a module, add the following to /etc/modules.conf:

alias block-major-97 pktcdvd

Finally, create the packet driver device nodes in /dev, add one node for every CD-RW drive you want to support:
mknod /dev/pktcdvd0 b 97 0
mknod /dev/pktcdvd1 b 97 1
...		 








Installation of udftools


Install udftools by running the following commands:



  
    

       ./configure --prefix=/usr &&

make &&

make install

      		
    

  







Contents


The udftools package contains the utility needed to set up and break
down connections between a kernel packet driver and a CD-RW disk drive,
the udf filesystem tool, and a utility to manage CD-RW drives. 
Man pages are included.








Description




pktsetup


pktsetup is used to establish and break down associations between
the kernel packet driver and a physical drive.








cdrwtool


cdrwtool provides facilities to manage CD-RW drives, including
formatting new disks, setting the read and write speeds etc..








mkudffs


mkudffs is used to create new udf filesystems, it can be used on
hard disks and CD-R as well as CD-RW.










Configuring udftools


There is additional material, including details of usage and a
sample bootscript in the LFS hint:




 http://hints.linuxfromscratch.org/hints/cdrw-hint.txt




However, the following commands illustrate the usage of the tools:





  
    

      
      

cdrwtool -d /dev/scd0 -q

pktsetup /dev/pktcdvd0 /dev/scd0

mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime

      		
    

  





Command explanations

cdrwtool -d /dev/scd0 -q: prepares a new CD-RW for use and formats it
with a udf filesystem.

pktsetup  /dev/pktcdvd0 /dev/scd0: associates the physical device
/dev/scd0 with the kernel packet driver /dev/pktcdvd0.

mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime: mounts a udf
formatted CD-RW for read/write access. See man mount for details of the
switches available for udf filesystems.
