1)  On systems running Upstart, shorewall-init cannot reliably secure
    the firewall before interfaces are brought up.

2)  The generated firewall cannot detect the gateway added by recent
    versions of dhclient.

    Corrected in 4.6.5.1.

3)  In 4.6.5, the bash-based configure script would issue the following
    diagnostic if SERVICEDIR was not specified in the shorewallrc
    file.

      ./configure: line 199: [SERVICEDIR]=: command not found

    This is compounded by the fact that all of the released
    shorewallrc files still specify SYSTEMDDIR rather than SERVICEDIR

    Corrected in 4.6.5.1.
