It used to work, with udev and the rules.d files. > So, if you are not happy with those names being used the way they are > by the kernel, then you will have to arrange it to name them all > twice: first to some other name series (eg en0, en1, en2) and > thereafter back onto the original name series (eth0, eth1, eth2) on > the basis of some other adapter property (eg macadress). I think you have given an excellent description of what is going on. 1. Why is this so totally different from what I could previously do using /etc/udev/rules.d/70-persistent-net.rules under jessie and earlier releases? 2. https://wiki.debian.org/NetworkInterfaceNames clearly says that if you upgraded a machine from jessie to stretch and to buster (which for these purposes I regard as the same as jessie to ascii to beowulf), then it will continue to work as before, so - what is the difference between doing those upgrades, and doing a fresh buster / beowulf installation? What needs to be changed on a beowulf machine to make it work the same as a jessie machine upgraded to ascii, upgraded to beowulf? And, of course, finally: 3. Once /etc/udev/rules.d/70-persistent-net.rules no longer works at all under Chimaera, what is the correct / official way of getting interfaces named as you want them, according to their MAC addresses? Thanks, Antony. -- I bought a book about anti-gravity. The reviews say you can't put it down.
