Can't save firewalld rules with --permanent

Question

I just installed Fedora 23 Server. I have a single zone created by default:

# firewall-cmd --get-active-zones
FedoraServer
  interfaces: eth0

If I add a service to this zone, it works fine:

# firewall-cmd --zone=FedoraServer --add-service=http
success

# firewall-cmd --zone=FedoraServer --list-all
FedoraServer (default, active)
  interfaces: eth0
  sources:
  services: dhcpv6-client http ssh
  ports:
  masquerade: no
  forward-ports:
  icmp-blocks:
  rich rules:

But it is lost when running firewall-cmd --reload.

If I try to make it permanent as suggested in this answer, I get the following error:

# firewall-cmd --zone=FedoraServer --add-service=http --permanent
Error: INVALID_SERVICE: 'cockpit' not among existing services

I'm surprised as this is a fresh installation from an OVH template.

How to work around this error?

Answer 1

As suggested by Michael Hampton in the comments, this seems to be specific to the OVH Fedora 23 Server template.

I searched for cockpit in /etc, and found the following file:

/etc/firewalld/zones/FedoraServer.xml

Which contains the following lines:

<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>
  <service name="ssh"/>
  <service name="dhcpv6-client"/>
  <service name="cockpit"/>
</zone>

I removed this line and saved the file:

<service name="cockpit"/>

And it now works!

They basically seem to have added a default service to firewalld, that is not installed in their template.
