Puppet

If no logging destination is set, puppet agent will attempt to add the syslog log destination, but this feature is not available on Windows and this generates an error (though puppet continues running):

If a file destination is specified, e.g. puppet agent —logdest=c:\log.txt, puppet doesn’t log to the file, because the file log destination only “match"es paths that start with ‘/’:

Puppet::Util::Log.newdesttype :file do
  match(/^\//)
