One way to handle this: when firewall rules are saved through firewalld (or iptables-services), it should also ask NetworkManager to save the network device names involved by their MAC addresses. Except when it knows a MAC address wouldn't be stable (e.g. tun/tap device with a kernel generated MAC address) or when running in a VM. The kernel could help in identifying devices would unstable MAC addresses. Just a documented and supported way to avoid reconfiguring the firewall on Fedora upgrade when network device name policy could potentially change would also help. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
