Remove dependencies on ruby-ng and redis2

Right. Conditional dependencies. I think everybody has been wanting that from Chef from the beginning of time. :-) Personally, I don't care that much about having extra cookbooks on my server though, but I see your point.

I think this:

https://github.com/onehealth-cookbooks/apache2/blob/master/recipes/logrotate.rb

is the kind of "loose coupling" you are looking for ... plus a case statement type thing for the different ruby type (i.e. auto or none at the moment). Basically if you use the apache2::logrotate is called and you didn't otherwise have the logrotate loaded, it'll blow up.

Sure, I can do that. 👍

I've thought a lot about this and in the short-ish term, I'm just going to leave this as is. I want the default to "just work" for newcomers to Lita. Making them loosely coupled would cause extra steps by those folks. And my first priority needs to be those who want to use Lita and may or may not know all that much about Chef and how to upload cookbooks that are needed but not uploaded via Berkshelf.

That said, I'll look into a way to make the default / auto methods to install Ruby and Redis on their own and not use the external cookbooks. This will probably be mostly a copy/paste job from those cookbooks to get the basic setup going.

One more thing, if you don't have any unused cookbooks in your Chef server you have some trick I don't know about. I've got the windows cookbook required by some of the core community cookbooks and zero windows machines in my whole environment. 😄

I've decided to leave this as-is long term. I was going to take on maintaining "mini-versions" of the rubyng and redis recipes in the for those that wanted a turnkey solution. But that seems like a bad idea the more I think about it. I could be persuaded, but for now, I'm closing this.
