[chef] Include recipe if file exists.

[Doug Garstang < >]

All,

Trying to do a conditional include_recipe based on a file existing. Doesn't work due to compile/converge stage stuff.

A workaround was suggested here by the folks that should know:

https://tickets.opscode.com/browse/CHEF-5342

However, it doesn't work, just as someone else responded to the ticket with. They did not get a reply.

So, just to be clear, as suggested, this does not work:

unless ::File.exists?("/etc/foo/bar")

  include_recipe "foo::bar"

end
