  * d/squid.resolvconf: Invoke "systemctl reload --no-block" if we are
    using systemd. This prevents squid from blocking if the reload
    action is being issued indirectly because of another
    service (e.g., because dnsmasq has been restarted), which may
    cause a deadlock and prevent the whole transaction to
    complete. (LP: #1761096)
