By default, the NamePolicy=[1] (as configured in /usr/lib/systemd/network/99-default.link) is:
[Link] NamePolicy=keep kernel database onboard slot path This means that if the kernel claims to assign a predictable name, then that will take precedence over other policies, including the "onboard" policy, which appears to be the one you are expecting. So, maybe the previous kernel was just issuing ethX, which is not predictable, and "onboard" was the winning rename policy. It's also possible that something else is renaming the interface first, which means that the "keep" policy would take effect. Now, I think if you want to continue relying on the "onboard" policy, you should use a drop-in to give that policy higher priority. E.g.: $ mkdir -p /etc/systemd/network/99-default.link.d $ cat > /etc/systemd/network/99-default.link.d/name-policy.conf [Link] NamePolicy=onboard keep kernel database slot path I think that should fix your problem.
