Hallo Hans, > I need ext3 becouse i need > to store checksum files on a cd with ACL's. Proceed as follows: create an image of about 620M: # dd if=/dev/zero of=<ext3 img> bs=1k count=62M # mke2fs -F -m 0 <ext3 img> # tune2fs -j -c 0 -i 0 <ext3 img> # mount -o loop <ext3 img> /mnt/tmp copy your data to /mnt/tmp # umount /mnt/tmp and burn the image to iso (cd-rw): # cdrecord [blank=fast] dev=0,0,0 speed=<speed> -v <ext3 img> When mounting the cd you might need to specify the file system type using "mount -t ext3" depending on your /etc/fstab. Works like a charm. Bye, Leonard. -- mount -t life -o ro /dev/dna /genetic/research
