Subject Re: CentOS 7 support

Hi Marcus,

No experience with ACS and CentOS 7, but AFAIK the old init scripts should still work, though
ideally we should eventually use proper service files to take advantage of systemd.

Re firewalld, I tried to avoid it as much as I could as I believe it just complicates matters;
I am not necesarilly against it, but just chose to use good old iptables directly, I see it
more of a tool for begineers and it doesn't help if you already know your way around iptables.
I see similar trends of simplifying iptables also in the Ubuntu camp with "ufw".

CentOS 7 includes a package called iptables-services which implements the old behaviour of
loading up rules directly from /etc/sysconfig/iptables as well as making "service iptables
stop|start|save" happen.
