bind 现在包含新的 root 区域 KSK
由于 2017 年 10 月出现 DNS 安全扩展(DNSSEC)密钥签名密钥(KSK)滚动，因此一个新的密钥标签已添加到带有更新的根服务器和信任锚的 bind 软件包中。拥有最新的 KSK 是确保验证 DNS 解析器在滚动后继续正常工作所必需的。(BZ#1452639)
iptables-services 软件包现在支持 /etc/sysctl.d
有了这个更新，
iptables 或 ip6tables 服务的初始化脚本现在识别 /etc/sysctl.d 目录中的配置文件，以及 /etc/sysctl.conf 文件本身。因此，在重启 iptables 服务时，存储在 /etc/sysctl.d/ 中的用户提供的 sysctl 设置会被正确考虑。(BZ#1459673)
