[chef] Re: Re: chef-client runs only locally as root

[Gilles Devaux < >]

More on this:

I added these:
ohai-0.5.0/lib/ohai/plugins/ruby.rb:25 (inside run_ruby)
Ohai::Log.info("path: #{ENV['PATH']}");
status, stdout, stderr = run_command(:command => 'which ruby');

It seems ohai (or chef) runs inside a limited /usr/bin/env. Is there a way to 
add path at runtime?

I have a workaround using symlinks but it's not ideal.

Thanks
