Use with caution. Useful for patching a set of cookbooks on a machine
when iterating during development.

I noticed this when my production server host names were being listed in Chef activity after switching to a new deployment tactic. For example, it's fairly safe to assume that the command below will only run on staging:

    $ knife ssh -E stag "role:api" "foo"

Actually it runs on ANY node with role:api, which is not only unexpected but ludicrously dangerous in the case of deployments.

You can do this:

    $ knife ssh "chef_environment:stag AND role:api" "foo"

I did that after doing an emergency rollback. I'd like this documentation change to be done to avoid that happening to others. Happy to change wording of course.

Cache for syntax check is configured by syntax_check_cache_path. For
compatibility, the old moneta-specific cache_options[:path] will be used
when syntax_check_cache_path is not set (defaults to nil)

The opscode/chef repository now only contains the core Chef library code
used by chef-client, knife and chef-solo!
