The only reason im posting this is because im pretty sure that most of island life is just compiled addons from the community + takistan life on a custom map.
Add this to the top of the init.sqf:
gamerz971HDisLoveHeIsLife = 1;
publicVariable "gamerz971HDisLoveHeIsLife";
Not sure if this is required but I did it and it worked, add this to the end of each units init code in the editor.
gamerz971HDisLoveHeIsLife = 1;
