Customers who purchased the initial product (which was specific to RedHat 6.1 only and was available on one CD) did grumble about having a 2 CD set when they upgraded to the next release of the product. However, those who had installed the product themselves (rather than having us send out a Sales Engineer to do it) thought that the 2 CD inconvenience was outweighed by having all necessary upgrades and required packages available on the CD. Additionally, they thought having a script that could work out the missing packages and dependencies and install them in the correct order was an extremely valuable function.
Later customers have made no comment at all (either good or bad) on the 2 CD distribution enabling system. Perhaps this can be considered to be praise for a utility designed to facilitate installation--that it performs its job so quietly and efficiently that users don't really notice it.
