Edit your /etc/default/grub change GRUB_CMDLINE_LINUX=”” to :
GRUB_CMDLINE_LINUX="net.ifnames=0" If the biosdevname is installed you need to add :
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0" $ sudo update-grub
This creates a new /boot/grub/grub.cfg and for each entry in the line that starts with Linux there is a net.ifnames=0 usually after rw and the uuid address, so you can even add it manually there and reboot to see if the longnames have vanished and eth0 and wlan0 have re-established themselves.
I believe artix came with network-manager and it is aligned with gnome-systemd development which I believe is the source of long and “unique” interface names. If you have had problems dealing with them and want to return to the traditional eth(x) wlan(x) “logical” system, follow the instructions. It may not affect you and you might not care till one day your motherboard is fried and you move your disk to another machine. All network cards among other things will have to be reconfigured to new addresses. Some even say improves on the ability of outsiders to identify you. There was nothing unique with eth0 and wlan0!
