Thank you for trying.
I'm still very much a newbie ;/
I think I have an idea of what's intended.
The man-pages for cat and udev did not prompt fruitful questions.
What introductory material should I search for?
TIA
Missed the start of this thread but if it's related to having stable,
clear, IF names then I do it like this:
$ cat /etc/systemd/network/10-eth0.link
[Match]
MACAddress=00:16:3e:e0:71:00
[Link]
Name=eth0
I used to do it using udev rules but I changed and I don't remember why.
It might have been that udev rules don't play nicely with the kernel
naming on machines with multiple interfaces. I think you can get name
collisions while renaming.
(Despite the name of the directory, I don't use systemd)
