This is just a warning to Arch Linux users who update the the latest systemd.
Systemd now has “Predictable Network Interface Names”. More info can be found here: http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
Updating to the newest version will break networking! Requiring manual user changes. More info can be found here: https://bbs.archlinux.org/viewtopic.php?id=156283

This is probably a bit hackish, but here’s how I worked around this after updating systemd: <br> <br># Set the netcfg default wired interface to the new interface name <br># set WIRED_INTERACE=“ens3” /etc/conf.d/netcfg <br> <br># Setup network@ens3 service with the previous eth0 static IP configuration <br>ln -s /etc/conf.d/network@eth0 /etc/conf.d/network@ens3 <br>ln -s /etc/systemd/system/network@.service /etc/systemd/system/multi-user.target.wants/network@ens3.service <br>systemctl disable network@eth0.service <br>systemctl enable network@ens3.service <br> <br>(I also updated the kernel during this - not sure if that’s relevant)
