I tried both way, I mounted the ISO to /test then copy its full content to the root of my export and even left the ISO there just in case. I still see the error "That directory does not seem to contain a CentOS installation tree", do I have to dd the ISO I just did a simple cp -rf *

> /centos-media/centosdvd64,sync,all_squash)
> /centos-media/centosdvd32/DVD,sync,all_squash)
> After doing so, I also modified the entries under IPtables to allow traffic

Did you actually mount the ISO file, to expose the directory structure
to the netinstall script? I don't think it can read ISO's directly,
but I could be wrong?
