[chef] Problem with Service and notifies

[Ash Berlin < >]

I'm having some issues with defining a service for my app and notifying it to 
restart. The relevant parts of my recipe are:

link "/etc/init.d/x-ipan" do
  to "/opt/x/ipan/shared/ipan"
end

service "x-ipan" do
  supports :status => true, :restart => true, :reload => true
  action :enable
end

# Tidy up, remove the old name
service "ipan.staging" do
  action :disable
end
file "/etc/init.d/ipan.staging" do
  action :delete
end

nginx_site "ipan.staging" do
  enable true
  source "nginx.conf.erb"
  variables :root => IPAN_ROOT,
            :app_name => "ipan_staging",
            :server_name => "ipan.staging.x.com",
            :default => false
end

unicorn_config "/opt/x/ipan/shared/unicorn.rb" do
  listen "'#{IPAN_ROOT}/tmp/unicorn.sock'" => {:backlog => 2048}
  owner "ipan"
  group "x"
  preload_app true
  worker_processes 16

  working_directory IPAN_ROOT
  pid "#{IPAN_ROOT}/tmp/pids/unicorn.pid"
  stderr_path "#{IPAN_ROOT}/log/error.log"
  stdout_path "#{IPAN_ROOT}/log/out.log"

  seamless_upgrades true
  notifies :reload, resources(:service => "x-ipan")
end

The chef-client debug log is as follows.

[Thu, 26 Aug 2010 11:03:54 +0100] DEBUG: template[/opt/x/ipan/shared/ipan]

Then at the end of the run I get:

Any thoughts? Could it be something to do with the fact that the notifies is 
coming from inside the unicorn cookbook? (I'd hope not - services are global 
I thought)
