Just about piping : writing CD's is a real ONE time job.
Better be sure the program PROVIDING the data is real time .. and I don't think
mkisofs is anything but a "normal" unix (no-real-time) process. No suprise if doing
it in two steps (writing an image on hard disk, then burn it) tends to be more
reliable ...
for example, I could never get a direct burn cd-to-cdr to work properly. It is
supposed to work, but I just could not get it.
