What you're doing colud work. The problem is - you have NIC that's attached via USB, so the usual rules do not apply. The reason of it - /lib/udev/rules.d/73-usb-net-by-mac.rules, that's applied after your .link file rename an interface. To achieve a predictable (pun intended) behaviour - either create this zero size file: /etc/udev/rules.d/73-usb-net-by-mac.rules Or disable the offending feature altogether by adding "net.ifnames=0" to kernel's commandline. > OTOH the wired interface is always named eth0 (even with no .link file), even > if it should be > > # udevadm test-builtin net_id /sys/class/net/eth0 2>/dev/null > ID_NET_NAME_MAC=enx00160141ad18 > ID_OUI_FROM_DATABASE=BUFFALO.INC Systemd (udev is a part of it) is x86 centric. Unless NIC is connected to PCI or USB - it does not know how to rename them Predictably™. In your place I'd consider myself lucky - at least you have a network interface that's always called eth0, the way the kernel wants it. > Extra points if it involves getting rid of systemd altogether ;-) It won't help you here. To solve this particular problem once and for all, you need a replacement for udev, which Debian does not provide. Reco
