(untested) # dd if=3D/dev/zero of=3Dcontainer bs=3D1048576 count=3D650 # mdconfig -a -t vnode -f container # gbde init /dev/md0 # gbde attach /dev/md0 # newfs /dev/md0.bde # mount /dev/md0.bde /mnt # <copy files to /mnt> # umount /mnt # gbde detach /dev/md0 # mdconfig -d -u 0 # burncd data container fixate you should then be able to 'gbde attach /dev/acd0' and mount /dev/acd0.bde wherever you like.
