[Puppet Users] stdlib file_line type

If Puppet were actually doing that then it would suggest a bug in stdlib,
but I would be very surprised if that was what was really happening.


A file_line resource should never cause the same line in the same file to
be both removed and created during the same Puppet run. Not only would
such behavior constitute a poor implementation, inconsistent with my
general expectations of the agent's behavior, but also my review of the
code doesn't give me any reason to think it would manifest such behavior.

I could believe, however, that under certain circumstances Puppet fails to
recognize the presence of the target line in the file, and therefore on
every run it rewrites the file to add the line. Multiple copies of the
target line would result.

I could also believe that the log messages emitted by the file_line
provider are misleading.

To definitively sort this out, however, we need details of a resource
declaration and corresponding target file that trigger the behavior, and a
--debug log excerpt (from the agent) showing the messages emitted by the
provider when it applies that resource.
