See http://fy.chalmers.se/~appro/linux/DVD+RW/ > for more info. Hi; This is not technically true; once the pktcdvd mapping is made, the device can be accessed like a r/w block device. For example, after I associate the dvd with the pktcdvd device, I then can associate it with a cryptographic loop device, and mke2fs on that, then mount it and use it like any other filesystem. Something like: pktsetup dvd /dev/dvd losetup -e serpent-256 /dev/loop0 /dev/pktcdvd/dvd mke2fs -m0 /dev/loop0 mount -o noatime,rw /dev/loop0 /mntpoint I realize you are differentiating between burning an iso type image from what cdrwtool does, but I thought I would mention my usage;) Obviously this would not be compatible with anything else, which is intentional. What is the difference between using cdrwtool on the cd/vd-rw to form an initial image, and just doing a mkudffs on a pktcdvd associated device?
