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)  If 'noautosrc' 1s specified on a provider, then persistent routes
    and rules for that provider are treated as ordinary routes and
    rules (they are removed when the provider is enabled).

    Corrected in Shorewall 5.1.8.1.
