Re: no kickstart ?



The bugzilla is here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97892

I'll have to try out that patch tomorrow, though I suspect this will fix

We have our routers configured to forward dhcp packets appropriately so
that we don't have to run dhcp servers on every network.

Thanks,
