Comment # 6 on bug 884398 from Matthias Gerstner

I've submitted a change to address this issue to openSUSE:Factory and
SLE-12-SP3. The firewall script now checks for the presence of libvirtd and
sends SIGUP to it in case it is running. This happens only if the firewall
script rebuilds the firewall rule set.

On systems without a running libvirtd this shouldn't change the behaviour of
the firewall at all.

Closing this after the submissions have been accepted.
