Known issue: Firewall rules are not persisting on Ubuntu

[benjamin-robertson]

With the switch to the puppetlabs-firewall module in version 3.0.0. Firewall rules on Ubuntu are not persisting after reboot. The following error is logged when attempting to save rules.

Unable to persist firewall rules: Execution of '/usr/sbin/service iptables-persistent save' returned 1: iptables-persistent: unrecognized service

Management of firewall is disabled by default in this module for Ubuntu. Fix will be identified in the future. Users can still enable firewall, however rules need to be reapplied by Puppet after every reboot.
