"I always download the Kubuntu ISO onto my hard drive and
usually only burn off one CD. In the relatively short period since
Kubuntu 8.04 came out I have used that single CD to do about a
dozen fresh-installs, on four different computers, for various
reasons. On all the other releases of Kubuntu, since 6.06, I have
done at least as many fresh-installs on numerous computers from the
one CD throughout the release cycle."
