A patch to initramfs.img contents

Description of problem:
I've been using /usr/bin/livecd-creator and /usr/bin/livecd-iso-to-pxeboot
to setup my PXE booting environment on Fedora10, with success.
Recently I moved to Fedora12, and PXE booting fails with following error:

  dracut: root was live:/LiveCD.iso. liveroot is now /LiveCD.iso
  dracut: FATAL: Don't know how to handle 'root=live:/LiveCD.iso'
  dracut: Refusing to continue

Version-Release number of selected component (if applicable):
kernel-2.6.31.6-166.fc12.i686
livecd-tools-031-1.fc12.1.i686

How reproducible:
Create a LiveCD ISO using livecd-creator and use the ISO with 
livecd-iso-to-pxeboot to create PXE boot images.
Use the PXE boot images with PXE boot server (DHCP and tftp servers),
and boot a PC with PXE.

Steps to Reproduce:
1. Prepare a kickstart config file and use with livecd-creator to create LiveCD ISO image.
2. Use ISO image with livecd-iso-to-pxeboot:
  # livecd-iso-to-pxeboot ./LiveCD.iso
3. Copy the created content to PXE boot environment and boot PC with PXE.
  
Actual results:
Get error on System boot:

  dracut: root was live:/LiveCD.iso. liveroot is now /LiveCD.iso
  dracut: FATAL: Don't know how to handle 'root=live:/LiveCD.iso'
  dracut: Refusing to continue


Expected results:
Should boot up to login prompt of Linux or GDM.

Additional info:
I have created a patch for contents of initramfs-2.6.31.6-166.fc12.i686.img
file.
The patch does:
1. Adds new "liveiso:" directive for the root image to
  /cmdline/30parse-dmsquash-live.sh file.
2. Adds new script to generate udev rule file accordingly.
  /pre-udev/30dmsquash-liveiso-genrules.sh
