Hello Kai,

I stopped using renderd because of the crashes I got (it can be a thread 
race condition bug since the bug disappears when running renderd with 

I fully agree about the need of a real release process: it took me many 
days to figure how to have Nominatim and Tirex running, mainly because 
the information is split in different wiki pages written from 2010 to 
early 2013 (I ignored ealier info)  and none of them reports the release 
numbers used when wiki entries were written. One also have to search in 
mailing list to fix issues that show up one after the other. It was a 
painful road, nearly each step of the installation brings a new step 
that does not work at first, it may be necessary to backtrack to some 
earlier step, change of version/package, retry, etc.

For instance F18 provides postgreql 9.2 but postgis 1.5: one has to get 
postgis 2 but also to apply legacy.sql, bring stuff from mapnik source 
code, get files (like coastlines) from here and there, figure how to 
configure postgresql (that I never used before) etc.

I'm actually trying to configure a secondary system to check that I 
didn't forget to note something, to be able to reinstall a system if 
this is needed in the future: I have currently a list of about *60* 
different things to do one after the other and I still have to add Tirex 
setup (and pray that the resulting system is a working one). I have to 
save copies of the versions of the different projects to be sure of what 
I use since I can't rely on stable versions of different components. And 
if someone is using that list in a couple of weeks, some parts will have 
to be updated/rechecked etc. so the installation is messy at best.
