Figured.  That't the current setup.

Sounds like a nice option, however this is before the system has any IP 
addresses so I don't suppose it will be able to syslog remotely :)

I will look in to this.

It only gets to Anaconda init before trying DHCP, so I doubt either of the 
above log methods will work.  What would you look for in a packet capture?  I 
guess the kickstart file could be sniffed from the wire?

Got it.  Thanks again for your help with this.
