Comment 6 for bug 234122

@Andrew, thank you kindly or the patch. I agree with David that being in Recommends is enough to ensure that it works in the default (and most) installations.

This only causes an issue if the user:
  * uninstalled iptables
  * specified --no-recomends

I think both of these situations are an edge case in themselves. If a user has gone to that much effort to customise their system, i do not feel it is unreasonable for the default fail2ban configuration to require local editing.

Thanks again Andrew.
