[chef] Re: Is attribute values combination accross cookbooks possible?

[Daniel DeLeo < >]

Ohai!
If you'd like to stick with 0.7.16, you can use set_unless to set the
attribute to an emtpy array if it doesn't exist, then append a port to
the array with the << operator (or use the push or unshift methods).
There's no way in 0.7.16 to ensure that a given set of attributes is
loaded before another, so you'll want to put the set_unless in both
attribute files.

HTH,
