There are two methods to include any python patch to the anaconda 
installer.  You can make an updates.img image with the patches and place 
it somewhere in the installation tree or you can create a RHupdates 
directory and place it somewhere in the installation tree.  The exact 
place to put it may vary but you can look in anacondas docs 
(/usr/share/doc/anaconda-#.#.#.#/install-methods.txt) to see where to 
put it.  I use the image method with a script  to do all the dirty 
work.  I use `sudo` in the script because I have to access a shared 
installation tree and need to be root to write any changes, but if you 
have a different setup in your office you can change it.
I've used it for fc6 and rawhide and it works fine.

#!/bin/bash

# This scrit is used to change the updates.img images in the anaconda installer.

use()
{
    echo If there is an images in the directory with the same name, it will be erased.
    echo The correct way to use uploadfilesCramfs is:
    echo uploadfilesCramfs /Destination/Path/NameOfImage file1 file2 file3 ...
}

if [ $# -lt 2 ];then
    use
    exit 0
fi

IMAGE_PATH=$1
TMP_DIR=/tmp/CramfsTEMP
shift
j=0
for i in $*
do
    FILES[$j]=$i
    j+=1  
done

# Lets erease the previous output file 
echo If you do not erease the previous image the result may vary.
echo For the mkfs.cramfs and rm command to be executed the current user $(whoami)
echo Must be on the sudoes file.  just add "$(whoami)    ALL=/sbin/mkfs.cramfs"
echo and "$(whoami) All=/bin/rm" to the sudoer file.
echo To edit the sudoer file exec visudo as root.
sudo rm -vfi $IMAGE_PATH

# Lets make a temporary directory

    cp -vf $i $TMP_DIR

sudo /sbin/mkfs.cramfs -v $TMP_DIR $IMAGE_PATH

# Lets erease the temp directory

# We are done!!!!
