Comment # 19 on bug 926835 from lynda t

After making the script edits above, then rebooting

systemctl enable sshd@br0.service
    Failed to execute operation: No such file or directory

ls -al /dev/br0
    ls: cannot access /dev/br0: No such file or directory

ifstatus br0
    br0             up

Obviously, there's no available sshd service.
