[chef] How to update chef-client on nodes?

[Greg Barker < >]

When I created the nodes I specified the bootstrap-version argument in knife. Since then, chef-client has been updated. How do I get the new chef-client on my nodes?

I'm using the chef-client cookbook, but I didn't see a way to specify the client version to install (or a URL to download it from) in the attributes there.

Thanks!
