Now Kdump will ingore the DNS config in /etc/resolv.conf, when it generates the initram. And most users do not concern about this issue, because they never use deployment tools to configure machines environment, like puppet.
Minfei, there's a long discussion in Fedora devel list about some future changes about DNS, kdump may need change as well. FYI the url: https://fedoraproject.org/wiki/Changes/Default_Local_DNS_Resolver
It is more convenient to add the DNS config to /etc/resolv.conf for people who use deployment tools to configure machines concurrently.
