John,

I used unsquashfs for stage2, edited usr/lib/anaconda/dispatch.py
changing the following lines.
    ("methodcomplete", doMethodComplete, ),
    ("dopostaction", doPostAction, ),
     changed to;
    ("dopostaction", doPostAction, ),
    ("methodcomplete", doMethodComplete, ),
ran ksquashfs on the unsquashed stage2 and it worked fine! :)

full description below... I was using BlueOnyx-5.2-20090107.iso

# Do the following to fix the issue not running %post scripts:
# Note that the *.img files use the squashfs file system.
# if the tools are not on the system yum install them. 
  yum -y install squashfs-tools mkisofs cdrecord
# insert install-cd into cdrom
  mkdir /mnt/cdrom
