[Spacewalk-list] Kickstart/DNS issue

[Mike Wilson]

Josh,

Thanks for the reply. I'm not having any luck with the pre-script though.
It doesn't seem to be making a difference. I'm a little confused as to
how/when the pre-scripts run. How do you write to /etc/hosts when the file
system hasn't even been created yet?

Is there some way within spacewalk to tell it to just use the spacewalk
server's IP address instead of it's hostname?

Also, I'm still very confused as to why it's trying to resolve reverse DNS
for an IPv6 address.

Mike
