Knife Plug-in to print a chart of all cookbooks and the version constraints contained in each environment.
Also highlights which cookbook versions are frozen, which constraints are 'behind' the latest version, and if any constraints are obsolete (i.e. cookbook does not exist).
Out put can be either to the console, or in html format.
Ohai plug-in to gather lvm layout.
Updated to Ohai Version 7. Thanks to Stephen Wright for the update.
