Hi Lynn,

The ruby dependencies are necessary for bosh-init, because it renders manifest templates with ruby. See https://github.com/cloudfoundry/bosh-init/blob/master/templatescompiler/erbrenderer/template_evaluation_context_rb.go for all its beauty.

Warm regards
Marco

Subject: [cf-bosh] Re: bosh-init install question

bosh-init (or the new bosh2 cli's create-env command) will download some yet-to-be-compiled modules called CPIs. Some CPIs are written in Ruby - the ruby itself is also downloaded automatically and installed in a special private place; but Ruby has some system dependencies to work. Instead of also downloading those as well, the CPI module will just require that you have them pre installed.
