systemd/udev: PredictableNetworkInterfaceNames

Posted by jpluimers on 2017/08/28

This is so cool, but will take some time for lot’s of tooling to become compatible:

Starting with v197 systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces. This is a departure from the traditional interface naming scheme (“eth0”, “eth1”, “wlan0”, …), but should fix real problems.

The MacMini is a bit dumb as it won’t enable the GPU when there is no display attached. Which means headless operation is cumbersome as display rendering is very slow.

There are a few tricks of which the off-the-shelve HDMI solutions work best.

You can buy them at Amazon:

Basically the trick to simulate a monitor with a dummy load works for other display connectors as well (most of them work fine with 75 ohm resistors, usually a bit lower or higher works just as well):
