今天遇到一个神奇的现象，我对CentOS 8系统做初始化之后再重启系统，发现系统不能通过NetworkManager获取DHCP IP了

查了系统日志发现是：

通过谷歌搜索发现这是一个NetworkManager的BUG

BUG描述链接：

https://bugzilla.redhat.com/show_bug.cgi?id=1744427

既然知道了是BUG，也就知道了问题原因；在CentOS 8还没有对应更新NetworkManager软件包的情况下，我们只能把系统的hostname修改为localhost，来避开这个BUG

for i in static pretty transient; do hostnamectl set-hostname localhost --$i; done

修改完成后就可以重启自动获取DHCP IP了
