Ubuntu service idempotence

[sor...@gmail.com]

I'm seeing some idempotence issues around enabling services in Puppet 3.7.4 on Ubuntu 12.04:

root@ubuntu-server-1204-x64:~# puppet resource service ntp enable=true

Notice: /Service[ntp]/enable: enable changed 'false' to 'true'

service { 'ntp':

  ensure => 'running',

  enable => 'false',

}

root@ubuntu-server-1204-x64:~# puppet resource service ntp enable=true

Notice: /Service[ntp]/enable: enable changed 'false' to 'true'

service { 'ntp':

  ensure => 'running',

  enable => 'false',

}

Does this Ubuntu version require a custom (read as: non-upstart) provider?
