This is probably not a direct answer to your question, but might be helpful:

ISO images can be mounted as filesystems. In linux you would do
something like mount -o loop /path/to/your.iso   /path/to/mnt
In FreeBSD, you would need to create a memory disk and mount it, i.e.

mdconfig -a -f /path/to/your.iso

(response) md0

mount -t cd9660 /dev/md0  /path/to/mnt

you can then copy the files, and modify what you need.
In order to make boot CDs again,  you would need to use cdrecord with
suitable options, which I don't remember by heart.

BUT, you may look at the instructions on the following page:


there are instructions to create a bootable DVD from FreeBSD cdroms, and
I can confirm the procedure works perfectly.
