Neither Ansible nor Puppet takes 6 months to configure. Yes you have to write the code (and/or pull pre-existing modules) to make the config changes you want, but that's the point of them: they are there to automate the changes of config on servers. If you don't want to change the config of a base install then there is nothing to write. And given config is going to be specific to your environment then of course you're going to need to customise your config management code. No two companies are going to want their servers set up exactly the same.
