or folks writing Chef cookbooks / Puppet modules that create the config 
files from templates! :)

Having just gone through this effort for the OpenStack Network Chef 
cookbook [1], I can say definitively that it was a major pain in the 
butt to templatize that database config section for every single Quantum 
plugin.

My only complaint is that the changes weren't completed before I went 
through the effort ;)

Yes, a gentle reminder out to the -operators or -dev mailing list each 
time a config file is changed would be most welcome!
