ServerSpec Notes

These are snippets of auto-generated from ServerSpec. The serverspec-init only auto-generates base functionality with cmd, exec, ssh, and winrm backends with some optional vagrant support for dyanmic inventory on ssh backend.

There are additional backends available from SpecInfra, but these are not supported and only documented in O'Reilly book for Serverspec: The Definitive Guide by Gosuke Miyashita (ISBN978-4-87311-709-6), which is in Japanese only:
