Ubuntu14.04でservice startが1を返すためchefがエラーになる現象を回避

Ubuntu12.04LTS

$ lsb_release -r; sudo service nginx start; echo $?
Release:        12.04
Starting nginx: nginx.
0

Ubuntu14.04LTS

$ lsb_release -r; sudo service nginx start; echo $?
Release:        14.04
start: Job is already running: nginx
1

この動きはどうなんだと思う. ;; serviceで上げ下げする前に必ずstatus見ろってこと?
結果として, chefを実行したときaction :startが失敗扱いになる.

# If the currently running init daemon is upstart, return zero; if the
# calling init script belongs to a package which also provides a native
# upstart job, it should generally exit non-zero in this case.

   if [ -x /sbin/initctl ] && /sbin/initctl version 2>/dev/null | /bin/grep -q upstart; then
       return 0

にコメントが書かれており, initctlがupstartなら0を返す動きになる.

ので,
https://github.com/andreychernih/openssh/commit/ee011fdda086547c876bceff79f63d751d0893b9 あたりの解決策を見るとserviceブロックにproviderを渡せばよさそう

+service_provider = Chef::Provider::Service::Upstart if 'ubuntu' == node['platform'] && Chef::VersionConstraint.new('>= 13.10').include?(node['platform_version'])
 service 'nginx' do
+  provider service_provider
   supports :status => true, :restart => true, :start => true
   action [ :enable, :start ]
 end
