Archlinux下修改网卡名称

刚刚安装了Archlinux，用的archlinux-2013.03.01-dual.iso镜像，最新的systemd将网卡名更改了，不在是原来默认的eth0/wlan0

我的ifconfig -a输出如下:

enp9s0: flags=4098 mtu 1500
ether 04:7d:7b:f8:25:9d txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

lo: flags=73mtu 65536
inet 127.0.0.1 netmask 255.0.0.0

RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

wlp3s0: flags=4098mtu 1500

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

怎么将网卡名改回原来的eth0/wlan0呢？如下操作即可:

#cd /usr/lib/udev/rules.d/
#mv 80-net-name-slot.rules 80-net-name-slot.rules.bak

如果/usr/lib/udev/rules.d/目录没有如上文件，那就在/etc/udev/rules.d/找，完成后重启电脑即可！
