[chef] Re: RE: Re: multiple clusters and attributes

[Brad Montgomery < >]

Just to be clear, I create a single role for the cluster, and specify
all nodes in that role. Then, apply that role to every machine.  I'm
not sure I made that clear in my last email, and I'm sure there's
probably a better way to do it.  I've also done similar things to what
 you've described in a data bag.

Do all of your clusters also need to know about each other?
