The UDFtools package contains pktsetup, cdrwtool, and mkudffs. pktsetup is used to establish and break down associations between the kernel packet driver and a physical drive. Example: pktsetup /dev/pktcdvd0 /dev/scd0 mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime associates the physical device /dev/scd0 with the kernel packet driver /dev/pktcdvd0, then mounts a UDF formatted CD-RW for read/write access. cdrwtool provides facilities to manage CD-RW drives, including formatting new disks, setting the read and write speeds etc.. Example: cdrwtool -d /dev/scd0 -q prepares a new CD-RW for use and formats it with a UDF file system. mkudffs is used to create new UDF file systems, it can be used on hard disks and CD-R as well as CD-RW.
