[chef] Preserve value between definitions call?

[Denis Barishev < >]

Hello chefs,

I was really surprised to find out that when the same definition is 
called one after one in the same recipe the recipe instance is different!
How is it possible? This messes up my understanding of chef again) The 
more I work with chef the more interesting moments I constantly find out)

I was trying to save a value as an instance variable of recipe, but it's 
occured that those were different recipe instances. So it seems like 
chef duplicates recipe instance when executing definition and probably 
resource. Is it true?

Do you see any clean ruby way to preserve a value between definition calls?

Thank you,
