I've no argument with the method of naming the interfaces with more
meaningful and stable names, though the OP's problem seems to have
been not using the new names to disambiguate them. But FTR, just a
couple of niggles:
Renaming an interface (that the kernel likely originally named as eth0
or eth1) to eth0 is a confusing thing to do. Pick a name that can't
clash with anything else: I would avoid anything that the kernel or
udev might choose. Popular choices are lan0, internet0.
A filename like /etc/systemd/network/80-mywired.link avoids overriding
systemd's /lib/systemd/network/99-default.link. I'm not sure why you
would want to override it.
Cheers,
David.
