###### Part of Chef run that fails #######
bash 'rhel_build_install' do
      user 'root'
      cwd Chef::Config[:file_cache_path]
      code <<-EOH
        tar xzf runit-2.1.1.tar.gz
        cd runit-2.1.1
        ./build.sh
        rpm_root_dir=`rpm --eval '%{_rpmdir}'`
        rpm -ivh '/root/rpmbuild/RPMS/runit-2.1.1.rpm'
      EOH
      action :run
      not_if rpm_installed
    end
  end
  
#### It fails because in 'build.sh' it runs "rpmdev-setuptree".
#### This creates rpmbuild directories in "$HOME/" but that doens't exist for the user/session running this script which _should_ be root.
#### So it creates them in "/" then the next line looks for "/root/.."
