Pretty much every time I call firewall-cmd I end up calling it twice:

% firewall-cmd --zone=public --add-port=7777
% firewall-cmd --zone=public --add-port=7777 --permanent

I think "do it right now and persistently" is usually what people want 99% of time.  It would be nice if firewalld made it simpler.

I'd really prefer if there were a `--temporary` switch to go along with the `--permanent` switch, so the default action without either is to make the change now and persistently, but some sort of `--permanent-and-runtime` switch would be okay too.
