[chef] Re: Re: Manage role-node association with scm?

[Lamont Granquist < >]

"knife download /nodes" will download all your nodes into your chef-repo

http://docs.opscode.com/knife_download.html

you can also just "knife download /" to get everything which will pull 
down nodes, roles, data_bags, cookbooks, environments, acls, clients, 
groups, and containers as well...

available in chef-client in 11.6, i think its available for everyone 
else in the knife-essentials gem
