Guys ..

In order to do a full install set, we need a certain set of packages.

This set of packages is pretty much set in stone (you need all the deps
to do every install in the comps set).  I can not really adjust this
package set unless we take some items off the installer.

This means that the DVD is indeed too big for some media.

If you are having issues and you HAVE to use a DVD and can not use a usb
key .. please use the minimal ISO or the NetInstall ISO instead.
