The following is needed from iiab 7.1:
cp scripts/local_facts.fact /etc/ansible/facts.d/local_facts.fact
cp roles/www_base/files/html/js/nacl-fast.min.js /library/www/html/common/js
cp roles/www_base/files/html/js/nacl-util.min.js /library/www/html/common/js
from maps
cp /opt/iiab/maps/resources/regions.json /etc/iiab
Of course you will be downloading tiles to maplist, not viewer.
And they are different versions of the tiles
