[chef] varnish configured correctly but not starting

[< >]

Chef folks,

I have a varnish recipe that ends with the following:

# Start varnish
service "varnish" do
  action [:start]
end

After I bootstrap the machine that runs varnish, I don't see varnish running. 
When I log into the machine, it's evident my varnish recipe ran, varnish
configuration looks good, and I can start varnish by hand (sudo
/etc/init.d/varnish start) with no problems.  

Any ideas?  Where should I look for logs showing what happened when the recipe
ran?  If it makes a difference, the machine is running 32 bit Ubuntu 11.04.
