Comment 1 for bug 1473483

Do we really going to support manual modyfication of config files?

Even accroding to the doc
>Note that the dnsmasq.template file is managed by Puppet so all changes are overwritten/removed when the Puppet container is restarted or the Fuel Master node is rebooted.

this is not supported, and, probably, we must implement this via UI or something, instead of manual modyfication.
