Missing 70-persistent-net.rules

[yena]

Hello, on several new setup the 70-persistent-net.rules is missing.
I Have run
# udevadm trigger --subsystem-match=net --action=add
but no file is created

Entry in 70-persistent-net.rules are very important when i will add new Network Interfaces ..

How can i solve it ?
Thanks!

We (and almost all other Linux distributions) switched to Predictable Network Interface Names, so 70-persistent-net.rule is not used anymore (not necessary).

See https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

Ok but now, using this new method, when i add a new hardware eth interface, proxmox rename old ones and i have to manually re-assign all eth.

Hi yena,
no - if you have valid definitions in 70-persistent-net.rules they are used.
But if you replace or add an networkcard, the new/changed nics are named with the new style (like enp5s0f0).
I have an host with mixed nic-names:

dmesg | grep renamed
[    1.036362] bnx2 0000:05:00.0 enp5s0f0: renamed from eth0
[    1.076314] bnx2 0000:05:00.1 enp5s0f1: renamed from eth1
[    1.149876] tg3 0000:02:00.0 rename6: renamed from eth1
[    1.188285] tg3 0000:01:00.0 rename4: renamed from eth2
[    1.208225] tg3 0000:01:00.1 eth1: renamed from eth0
[    1.238344] tg3 0000:02:00.0 eth2: renamed from rename6
[    1.258266] tg3 0000:01:00.0 eth0: renamed from rename4

I always thought predictable network interfaces were there exactly so that kernel does not rename interface, if you just add new one. So how's that possible (if as you say, Proxmox renames the old interface)?
