What's wrong with sh?

Chef is unnecessary boilerplate which makes you rely on other people's recipes to configure your own server. Also, Ruby for provisioning a Linux box, where's the fun?

Fair enough.

It took me weeks to figure out how to use chef. But it was totally worth it in the end. Although, I understand that you don't want to invest.

But come now, there can be fun in Ruby too :)
