I understood one of the benefits of linux was is small footprint. I was somewhat surprised to see the YD image is 3.6 GB I've been trying to download the release from a number of mirror sites to no avail. I ordered the disk, though it has not yet arrived. Do I truly need to download all 3.6GB to get an image of YD up and running? G5 dual cpu, 10.3.7 thanks, brian.
