Thanks Richard!  I believe Liam is using your libguestfs suggestion to
make the kickstart file available to the network-less DVD/CD installing
system.  It works rather nicely, thanks for the tip!

The next roadblock was booting the DVD/CD install while providing the
proper boot arguments ("ks=hd:vda:/ks.cfg").  An aside, I wonder if it
makes sense to request that anaconda automatically use a kickstart
if /ks.cfg exists.  Until then, we are using dogtail to start
virt-viewer, and provide the correct boot arguments to the installer.

Thanks,
James
