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.
Is this madness due to systemd or debian packaging? In either case I
think it should be mentioned in the release notes.
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.
I'll try what is explained here
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
ln -s /dev/null /etc/systemd/network/99-default.link
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.
I am lucky until systemd behaviour changes: do I have the absolute
certainty that, upon upgrading to buster, it will still be named eth0?
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.
Thank you, that was tongue in cheek (though the more I use systemd the
more I hate it).
