Hi,
I'll look forward to examining your rvm commands, to see where they
might be better than whats already in my rvm recipe.

Wouldn't really recommend using rvm head (yet) in production servers
because it can get broken pretty easily. This is a big reason why
people tend to prefer the standard opscode ree recipe. I've encouraged
Wayne to tag "more stable" commits with a stable release. And hoping
that Wayne will eventually just slow down the pace of it, and so
freezing certain features of rvm.

As for hardcoding the ruby versions into the cookbook, its reasonably
terse, but lacks a certain flexibility. One thing I have yet to do in
my rvm cookbook is to write a resource-provider  for rvm rubies. Still
working on the syntax which is in need of some improvement...

rvm_rubies do
  ruby :identifier => :default do
    ruby_version = "ree"
    flags << "--reconfigure" << "--jit"

    patches = []
    configure_flags = %w[]
    compiler_flags = %w[]

    ree_options = ""

    update = true
    update_rubygems = false

    force_install = true

    before do
      # some custom steps, like editing setup.rb ?
    end
  end

  ruby :identifier => :ruby2 do
    # ...
  end
end


For example, Rvm has a concept of the "default" ruby, so in the above
example, the :identifier resource attribute string is checked to see
if its been set to :default. That seems a bit flowery and might get
dropped in favour of

  rvm_ruby "ree" do
    default = true
    ruby_version = "ree"
    flags << "--reconfigure" << "--jit"
    # other rvm configuration options...
  end

It would be nice to look further into customizing the setup.rb script
too. Haven't figured that out yet either. Currently my rvm recipe uses
a whole bunch of cookbook attributes to set all these things. It will
take some time to switch that over to a resource-provider model.

Previously, it was just going to be a simple array of rubies to
install like: ["ree","1.9.1"], etc.
