Ok just to repost - here's the current delta to livecd-creator that I can't live without. The first part is answering "Why is my network pegged?" (though does anyone know if there's a nice way to use something like Wireshark to get this info?) The second is defaulting to a persistent cache for downloads. This is not protected against concurrent execution - should we go ahead and add a --nocache option for those people who have a local fedora mirror? Finally one random tip unrelated to this mail: use "ionice -c3 livecd-creator [OPTIONS]" if you're actually trying to use your laptop at the same time yum is making your CD. I wonder if it would make sense to just do this by default in yum?
