Purge unmanaged keys from /root/.ssh/authorized_keys

this doesn't seem to be as easy as i thought. Puppet doesn't provide a native way to purge it.

see

• http://serverfault.com/questions/316062/using-puppet-to-remove-ssh-keys-not-explicitly-allowed
• http://projects.puppetlabs.com/issues/1581

  resources { 'ssh_authorized_key': purge => true, }

doesn't make any difference.

the question is: is this release-critical ?
