Glad to hear it worked out ... it's still a bit wrong in koan even so 
and I'll see if I can't improve that.

Meanwhile, as for failed installs, this might be a good idea to do some 
testing on cobbler's kickstart tracking feature (/var/log/cobbler and 
"cobbler check").   I haven't heard many field reports on them, but that 
feature is basically designed to figure out if any kickstarts have 
stalled/hung/failed.
