Hi,

On a server, an interface previously named eno1

I never `touch /etc/udev/rules.d/80-net-name-slot.rules` (but the file
is installed by eudev) nor added net.ifname=0 to my boot command line.

I didn’t change the configuration on purpose, I only did the regular
updates. So, I have absolutely no idea why this happened. What could
have triggered it?


PS: Old interface names were way more guessable than the new ones (eth0
used to work 99% of time). I really don’t understand why someone woke a
morning a though “we should randomise this, it’s too much stable”.
