Since the recent systemd (udev) version, interface name is changed by udev 
rule 80-net-setup-link.rules.

You should see this message during the systemd upgrade:

:: Network device naming is now controlled by udev's net_setup_link
   builtin. Refer to the NETWORK LINK CONFIGURATION section of the
   udev manpage for a full description.

To keep the old way of naming ("eth0", ...), just touch to override the file:

# touch /etc/udev/rules.d/80-net-setup-link.rules

And after a restart, you'll get the old names back.

The .install script in systemd package should have handled this, though.
