[chef] Re: Version contraints in metadata

[Joshua Timberman < >]

Ohai!

For what it's worth, the "supports" attribute of metadata does not do 
anything at this time. It exists for documentation at this time.

If you'd like to have a recipe not get executed on a node of a non-supported 
platform and do that through metadata, you can do that in the recipe (or as a 
library with a method you send in the recipe).

For example:

https://gist.github.com/jtimberman/3695966

That doesn't support version constraint on platform_version in the 
#supported_platform? predicate method, so you'd have to add that logic.
