Do we really need/want this plugin in the development environment?

[mathias, 2016/03/21 16:36:22]

Actually I do not want any of these plugins in development, this file is merely
meant as an example. I expect nobody to actually use the role as-is, but even if
so, a plugin more or not should not matter. However, what about setting ensure
to "absent" for this one, but keep the grep being "present"? That would serve
the very same purpose, without the confusion about an unused plugin.

That suggestion sounds reasonable to me.

-    ensure: "present"
+    ensure: "absent"
   fluent-plugin-grep:
     ensure: "present"
