Description of problem: Kdump can dump the vmcore to remote nfs target if kdump was configred by using nfs dump and nfs target was mounted before building kdump initramfs. But if we use hostname to configure nfs dump, Though the kdump service will start successfully, dump will fail because there isn't a /etc/hosts file in initramfs. Resolution: copy /etc/hosts to initramfs.
