If this evolved into something like ninite for servers I would pay for that. I mean, install and configure apps that I select, secure the server, etc., also give me a file with all the passwords, configs, etc. that the script made so I can understand what it did.

I'm a developer, not a sysadmin by any means and it's daunting for me to setup a new server and then remember what and how I have re-configured. Usually I just follow my host's tutorials and never come back to tweaking anything.

Maybe something like that exists already, I've no idea.
