Yes, I have that.

I have created that directory (/var/lib/mod_tile), and the permissions
on it are 777. I have created a subdirectory (/var/lib/mod_tile/default)
for the only map section in my /etc/renderd.conf, that directory is also

My DocumentRoot for this virtual host is /var/www/technomancy.org,
however I shouldn't need to set the HASH_PATH (a.k.a. tile_dir) to that,
right? I'd like the map tiles served from /openirishmap_tiles/, i.e. not
the root of the site.

Also I checked the output of apache2ctl -t -D DUMP_MODULES and the
tile_module is loaded.
