[chef] FYI - .to_hash bug

[Phil Dibowitz < >]

Hey guys,

I just wanted to let people know I recently filed CHEF-4596.

It's a common thing in chef to call `.to_hash` on an attribute so you can loop
on it (iterating on attributes will usually give you not the thing you want
because of the way Chef autovivifies)...

Turns out in Chef 10... at least some versions... .to_hash will sometimes
de-dupe internal arrays of a hash. So if you have {:foo=>['a', 'b', 'a']} in
your hash somewhere, what you'll get is {:foo=>['a', 'b']} and this could
seriously mess some people up in very subtle ways.
