Disable systemd-udevd renamed network interface

Linux OS有時侯會出現eth0&eth1被系統改名為p3p1&p1p1
[    8.159878] systemd-udevd[190]: renamed network interface eth0 to p3p1
[    8.163860] systemd-udevd[193]: renamed network interface eth1 to p1p1

可以在boot command加入 net.ifnames=0 biosdevname=0 參數就能關掉 rename 功能, 使用原本的eth0&eth1

Fedora 18 下修改方式:
# vim /etc/default/grub

GRUB_CMDLINE_LINUX=".... net.ifnames=0 biosdevname=0" 

# grub2-mkconfig -o /boot/grub2/grub.cfg

# reboot
