Deprecation: Removal of support for Ohai version 6 plugins (OHAI-10)
Ohai 7.0 released with Chef Infra Client 11.12 introduced an improved plugin DSL model. At the time we introduced deprecations for the existing plugin DSL, which we referred to as V6 plugins. In Ohai/Chef Infra Client 14 we will remove the support for Ohai V6 plugins, causing a runtime error if they are used.
If you have custom Ohai V6 plugins installed using cookbook or bootstrap you will need to update these plugins to the Ohai V7 plugin format.
See the Ohai Custom Plugins page for additional information on writing V7 plugins.
