Normally one would use /usr/ports/sysutils/mkisofs to create a new ISO image containing the modified files and burn that ISO image on CD. However, the man page for mount_cd9660 (in FreeBSD release 4.9) gives this example usage of the command: The following command can be used to mount a Kodak Photo-CD: mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom This might be a bad example. Neither the man page for mount_cd9660 nor the man page for mount lists "rw" as option specifiable with the "-o" flag. The "-w" flag (which is not an "option") is listed on the mount man page but not on mount_cd9660 man page. I was under the impression that the mount_cd9660 command only mounted file systems read-only. Dan Strick strick@covad.net
