Client driven install

I would like to initiate a client driven install rather than through a knife bootstrap. Based on the Omnitruck install script it appears this will install the client but doesn’t setup the client.rb, client.pem or provide the chef server certificates. What is the best way to setup that part of the install?

We ended up writing bootstrap scripts in bash and powershell that calls out to the Omnibus install script prior to creating all of those files. It works on all of our platforms: Windows 2008r2/2012r2, AIX, Solaris, RHEL 5/6/7.
