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)  When SHAREDIR is not set to /usr/share/, the Shorewall-core
    installer fails to update lib.base and lib.cli to look in the
    correct directory for the shorewallrc file.

    Workaround: Edit the two files and modify the line following this
                comment to source the correct shorewallrc file.

        #
        # This is modified by the installer when ${SHAREDIR} != /usr/share
        #

    Alternative workaround:

        Edit install.sh and change these two lines replacing
        "${PRODUCT}" with "shorewall". 

            eval sed -i \'s\|/usr/share/\|${SHAREDIR}/\|\' ${DESTDIR}${SHAREDIR}/${PRODUCT}/lib.base
	    eval sed -i \'s\|/usr/share/\|${SHAREDIR}/\|\' ${DESTDIR}${SHAREDIR}/${PRODUCT}/lib.cli

        You can ignore the like that modifies lib.core, since that
        files does not actually require modification.

    Corrected in Shorewall 5.1.10.1.
