Arch Linux

UFW does not start either iptables.service nor ip6tables.service and works just fine without them. However, this package's sshguard.service is implicitly requiring them to be running which causes errors for users running ufw.

I don't know what the solution is, but the current implementation does not cover all firewall use-cases. Feedback from a knowledgeable person is needed :)

Additional info:
* package version(s) sshguard-1.5-16

Steps to reproduce:
1) Install ufw and configure it minimally so it will start and start it.
2) Install sshguard and start it. Now inspect `systemctl` and see the two failures of both iptables.service and ip6tables.service
