Thanks to Alan Crosswell for responding and being a "2nd set" of eyes. I am on
the same broadcast domain as the kickstart server but the DNS server is not on
the same subnet. I realized that my problem was in the /etc/cobbler/settings
file.
The issue was that for:
server: <full qualname>
next_server: <full qualname>
I was using the fully qualified domain name for the server instead of IP. The
python script picks this up and builds a file:
http://<cobblerserver>/cblr/svc/op/ks/system/<system name>
If you use the fully qualified name the file does as well. The issue is that
since it doesn't setup the DNS until later in the build the repo's can't be
accessed because it doesn't know where they are.
Once I changed them from name to IP everything worked like a charm.
