Ensure persistence of network config during first boot, future boot and in case NICs physically get added or replaced

[Martin-Weiss]

Just had the problem that durining initial installation the NIC was detected as ETH4 but after the first reboot the NIC was ETH0. So the load order of modules / race conditons etc. influence the NIC naming.

To persist this properly we have been creating udev rules based on PCI bus ID / SysFS or other ways (tried to avoid MAC addresses, because they change when NICs are replaced in existing devices).

-> could we get some sort of "create udev persistence" for the NICs NMC is configuring to avoid problems in case NICS are added / removed / replaced?
