Comment 8 for bug 2055333

Mantic with 0.106.1 correctly configures the loopback interface so it seems other package updates on the system aren't affected by the permanent mac address changeset. I suspect it is something with systemd but I haven't found anything definitive yet. The netplan file from cloudinit and the systemd generated network units all appear to have the same content between the OS versions. ethtool doesn't report a permanent address for loopback on jammy or mantic.
