• Chef up server using the tile role if necessary
• Create a temporary directory for the planet file under /store/tmp

• Stop chef-client, apache2, renderd and replicate services
• Check the drive has space free with df -h /var/lib/postgresql/*/main
• Load planet with sudo -u tile osm2pgsql --slim --database=gis --cache=0 --flat-nodes=/store/database/nodes --number-processes=16 --multi-geometry --hstore --style=/srv/tile.openstreetmap.org/styles/default/openstreetmap-carto.style --tag-transform-script=/srv/tile.openstreetmap.org/styles/default/openstreetmap-carto.lua planet-latest.osm.pbf

• Download fonts with cd /srv/tile.openstreetmap.org/styles/default/ && sudo -u tile /srv/tile.openstreetmap.org/styles/default/scripts/get-fonts.sh
