Using multi-session recording of the DVD is not necessary. As long as
you require loop-back mount, then you've got shell, cat, and dd. So the
CD images can be constructed from files within a single-session DVD
by using one shell script per output platter:
cat <leading-sectors> <directory-info> <file-list> \
| dd bs=32k of=/dev/cdrw
where <directory-info> is a file containing the directory portion of
the appropriate mkisofs.
