Ok lets me try this senario,
I have a copy of the existing cd. I created an image on the hdd, I
mounted the iso to a tmp folder and have extracted all the files to a
tmp dir. is there a way to extract the bootable img from the iso and
reuse it to recreate the cd with the now updated files in the tmp
folder?
