Comment 3 for bug 1860677

It could be seen as a *security issue*, in my opinion.

If a server or a user is expecting to block thing behind ufw install.
And then he/she install docker with its default, it will bypass the existing firewall configuration. So exposing thing that was blocked previously.

Without any notification.
