[Users] Settings lost after node reboot

[Nicolas Ecarnot]

Hi,

Migration failed due to a lack of an iptables rules about tls
> # libvirt tls
> -A INPUT -p tcp --dport 16514 -j ACCEPT

I added it in /etc/sysconfig/iptables and migration worked.

After a reboot, this rule is lost, as well as some setting I added in /etc.

I see the the nodes have very specific mouting strategies, and/or read 
only architecture.

I'm not sure I want to become an expert about why and how it's done, but 
I'd be glad if someone just tells me where I have to write my settings 
in order them to resist node reboot?

Thank you.
