I've got a bootable DVD image in UDF format. I'd like to add some more
files to the image before burning it, while preserving the bootable
part. There's plenty of information about how to create and burn an El
Torito image, but I can't find anything about how to find one on an
existing CD (image).

extracts the boot image from a CD.

Thanks. It turns out to be bundled with Debian's genisoimage package,
but `apt-cache search torito' didn't find it.

I had no luck in the end though. Although geteltorito read something
from the UDF image, it was only 2K long. Isn't it supposed to be exactly
either 1.2, 1.44 or 2.88MB? And anyway, mkudffs doesn't seem to have any
way to make a bootable image like mkisofs does.
