最近新安装的ubuntu 16.04,网卡命名和以前不同,据说15.10就开始了.

可以知道
Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da)
Classic, unpredictable kernel-native ethX naming (example: eth0) - depreciated
By default, systemd will now name interfaces following policy:
if that information from the firmware is applicable and available, falling back to

is not used by default, but is available if the user chooses so.
in all other cases.
如果自己命名
添加
