[chef] Ohai bombs out on start in fresh (VM) install

# ohai
/usr/lib/ruby/1.8/ohai/system.rb:120:in `join': can't convert nil into String 
(TypeError)
        from /usr/lib/ruby/1.8/ohai/system.rb:120:in `all_plugins'
        from /usr/lib/ruby/1.8/ohai/system.rb:117:in `each'
        from /usr/lib/ruby/1.8/ohai/system.rb:117:in `all_plugins'

        from /usr/lib/ruby/1.8/ohai/application.rb:67:in `run'
        from /usr/bin/ohai:40

The nil in question is @data[:os]. I don't know why it's nil because I
can't find where it gets set (invisible class initialisation for the
win!). Presumably it should be 'linux'.

I am using the ohai in plain ol' squeeze.

invariable experience that the company of a mere child is infinitely
preferable to that of a mere adult.
