[chef] Re: Force 'main' IP on multi-homed Chef nodes

[Troy Ready < >]

FWIW, the logic used to determine the automatic attribute ipaddress is
located here:
https://github.com/chef/ohai/blob/master/lib/ohai/plugins/network.rb

We've created custom ohai plugins for systems needing an ipaddress
override, and use the ohai cookbook
(https://github.com/opscode-cookbooks/ohai) to deploy them. Not sure if
I'd classify it as straightforward (was fairly daunting for me while I
was learning Chef), but it's the only way that I currently know of to
deal with automatic attributes.
