[chef] Re: Re: Re: Exposing attributes from cookbooks you depend on

[Lamont Granquist < >]

That's ideal philosophically, but is probably going to produce bad chef 
code.  One you've hit the computed attributes issue and worked around it 
by moving setting attributes in recipes and exposed yourself to 
compile/converge issues and started down the path of probably needing to 
use 'lazy' attributes, then I'd rethink the idea of re-namespacing the 
attributes.
