You need to run dracut to rebuild initramfs, or you wait for the next kernel

Is symlinking to /dev/null supposed to still work? We are seeing this on
Atomic Cloud images where the symlink is in place but net.ifnames=0
isn't on the cmd line so we are getting ens* interface names.

To expand on that from my experience:
If the network interface is loaded during early boot, it might be
renamed before the /dev/null symlink has an effect.
That might happen if you have the dracut-network package installed,
which injects network modules in the initrd.
In this case, you need to put the symlink in the initrd too. For
instance with:
cat > /etc/dracut.conf.d/10-udev.conf << EOF
install_items+=" /etc/udev/rules.d/80-net-setup-link.rules"
EOF
dracut -f
And then it shouldn't be renamed.
By the way, masking 80-net-setup-link.rules has a side effect of
breaking systemd-networkd. I'll open a ticket about it for maybe finding
a better alternative.
