RE: Editing ISO

I guess there is a third question, if I do mount, and have to cp -R to
some folder. Make my changes, and use mkisofs to recreate the ISO, how
do I find out what file the current boot loader is pointing at and is
their anything to do to creat a bootable CD other then us the mkisofs
eltorito-boot option and point it to that file?

Q1) Would this not be read only?
Q2) If I have to remake the ISO using mkisofs would I not destroy the
boot information from the original volume?

Mount the ISO using loopback file system:

modprobe loop
mount -t iso9660 -o loop output.iso /mnt

Edit the file under /mnt.

Then create the new ISO image (like with mkisofs or mkhybrid).
