The live image installation is more fast than Anaconda DVD Installer.
Is posible build a installer based on Fedora DVD installer that install a customized liveDVD image?. I guess that the installation will be more faster.
The problem for big liveDVD (4GB) installations is the RAM memory requirements during the installation. The Fedora DVD installer only need 1 GB or 512 MB.
Maybe this is imposible, what should I do for a faster installation from DVD.
