Just for a little clarification (my brain cells haven't got anywhere
near pedantry yet).  On a laptop with F7 with a F8 install DVD complete
with depsolve bugs, do I copy the DVD contents to the hard drive and
point Jigdo(-lite?) to that and burn a new install DVD when Jigdo is
finished; or can I use the DVD as the place for Jigdo to scan?  But then
how do I make new install media?
