+# - ==========
+# - How to rename network interface back to eth* (instead of i.e. enp0sXX)
+# - ==========
+
+Solutions:
+==========
+
+1.) Add 'net.ifnames=0' to parameter 'GRUB_CMDLINE_LINUX' at /etc/default/grub
+
+      GRUB_CMDLINE_LINUX="aufs=tmpfs console=tty0 console=ttyS0,38400n8 reboot=bios net.ifnames=0"
+
+
+2.) (not tested!) Create a file /etc/systemd/network/10-eth.link with the contents
+
+      [Match]
+      MACAddress=ff:ff:ff:ff:ff:ff
+      [Link]
+      Name=eth0
+
+replacing ff:ff:ff:ff:ff:ff with the MAC address of the device you wanted to change.
+After reboot the name was as desired.
