This looks like an organized collection of bash scripts with standard libraries for basic configuration processes, much like the fundamentals of Puppet and Chef.
This is great for simple initial setup (I'm sure a lot of us already have some short bash scripts to similar effect). However, Chef is great for maintaining multiple similar servers and keeping things standardized across machines with minimal effort. Chef also gives you some handy tools like automatic deployment and ERB templates.
I'm using Chef with 7 servers on Slicehost right now, and it's easy as pie once the recipes are set up and your server is deployed.
