Shorewall pretty much got out of the module loading business in
version 5.2.3. On systems with module autoloading enabled, however,
the 'shorewall show capabilities' command can result in the module
being autoloaded, unless you do something like you have shown above.
Note that Shorewall 5.2.3 will still attempt to load helpers because
they are never autoloaded (xt_geoip is not a helpter).

Also

        ?IF __GEOIP_MATCH

will trigger the module being autoloaded, unless such loading is
disabled outside of Shorewall.
