[OSM-dev] Cannot render tiles using Mapnik: "Bad file descriptor"

Using "strace" I figured out that it tries to load
  /home/maptiles/mapnik/world_boundaries/shoreline_300.shp
which was missing.

Googling around I downloaded the missing file from
http://tile.openstreetmap.org/shoreline_300.tar.bz2

Now my installation renders the tiles as expected :-)


However I still don't understand what's the use of the <name>
parameter for render_tiles() and why the script by default contains a
number bounding boxes for german cities that in consequence get
rendered explicitly?
