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

2)  The 'enable', 'reenable' and 'disable' commands do not work
    correctly in configurations with USE_DEFAULT_RT=No and optional
    providers listed in the DUPLICATE column.

3)  Shorewall6-lite fails to start under systemd.

    Workaround:

    - Edit /lib/systemd/system/shorewall6-lite.service and correct
           the ExecStart line:

           "/sbin/shorewal" should be "/sbin/shorewall"

    - Run "systemctl daemon-reload"

    Corrected in 5.1.0.1

4)  The PAGER setting in shorewall[6].conf is not propogated to remote
    firewalls by the 'export', 'remote-start', 'remote-reload' and
    'remote-restart' commands.

    Workaround: Define PAGER in
    /etc/shorewall[6]-lite/shorewall[6]-lite.conf.

    Corrected in 5.1.0.1

5)  The output of 'shorewall show macros' is garbled in version 5.1.0.

    Corrected in 5.1.0.1
