ruby - Chef Cookbook から SASS をデーモンとして起動する

Question

SASS --watch を Chef Cookbook からデーモンとして起動するためのガイダンスを期待していました。以下はうまくいかないようです：

lib="/vagrant/lib"
sassPath="#{lib}/sass"

include_recipe 'ruby'

execute 'install-sass' do
    command 'gem install sass'
end

execute "mkdir-lib" do
    not_if {File.exists?(lib)}
    command "mkdir #{lib}"
end

execute "mkdir-sass" do
    not_if {File.exists?(sassPath)}
    command "mkdir #{sassPath}"
end

execute "create-procfile" do
    command "nohup sass --watch #{sassPath}:#{lib} &"
end

Chef は正常に完了します。sass --watch をサービスとして実行する方法はないようです。
