It was, however, at least on F 18:

- you need /var/lib/tirex, owned by tirex user.

- you need /var/run/tirex, owned by tirex user. However /var/run is 
cleanup at each reboot on F18 so this dir must be rebuilt at each boot.

- tirex renders tile for a map named 'default', hence you need to have 
for instance /var/lib/tirex/tiles/default. Probably the name 'default' 
can be changed somewhere.

- tirex needs two processes 'tirex-master' and 'tirex-backend-manager': 
you have to figure how to start them when the system boots. Both scripts 
support '-d' (debug) which is very handy to understand where it fails.

- these two processes refuses to run as root. Since you must be root to 
make /var/run/tirex, you expect to write a script that runs as root to 
make the directory and  then uses 'sudo' to run the tirex processes. 
sudo will complain about being run without a tty, change /etc/sudoers to 
allow tirex commands to be run without 'requiretty' :-)

- if ever tirex complains about an 'internal renderer error', it can 
come from fonts not found by mapnik. Fonts location is declared into 
/etc/tirex/renderer/mapnik.conf. If using the name 'default' for the 
map, tiles location must be specified in 
/etc/tirex/renderer/mapnik/default.conf, as the location of the osm.xml 
file, the name of the map ('name=default') and the zoom levels.

I still load /etc/renderd.conf from the virtual-host files 
('LoadTileConfig /etc/renderd.conf") but I don't know if this is useful 
(I also have "ModTileRenderdSocketName /var/lib/tirex/modtile.sock"), 
the only statements in my renderd.conf are 'num_threads', 'tile_dir' 
(probably useless since it does not end with 'default') and URI.
