Hi,
After system update, eth0 device is renamed to enp5s0 by systemd-udev. It makes no network interface available on the system. How to fix it?
Thanks

append "net.ifnames=0" to kernel command line. It will prevent renaming.

The system is installed with grub2 and udev-215.

Adding this option in boot command line does not make the system keep older eth name.

Do not know about systemd, but you can double-check if option is passed properly by running cat /proc/cmdline.
Below is cmdline from one of my boxes.

Code:
~ $ cat /proc/cmdline
root=/dev/sda1 net.ifnames=0 video=LVDS-1:d

It works with udev-215 and grub2 just fine.
Check out whether option was added to command line or not with 'cat /proc/cmdline' ?

Oups, a bit late.
