Puppet & Chef are simply about configuration management. Puppet architecture is pretty awesome - but the puppet master itself can't be a stock CentOS 5.x system because ruby 1.8.5 is too ancient. I suppose you can use Karanbir's ruby-1.8.7 packages (or better yet, enterprise ruby packages) if you insist on running the server on CentOS 5.x. The thing about puppet is that the barrier to entry is rather high - it takes some time before you get to something useful whereas Chef is more adept at putting other people's recipes into service fairly quickly. Then again, you will run into barriers with Chef that don't exist with puppet so it seemed that the ramp up investment had long term benefits. Craig
