site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com I will see if I can work out the metapackage method. Thanks Mark Which package format? _______________________________________________ Do not post admin requests to the list. They will be ignored.

I am actually using Iceberg to create the package. The format is the default pkg format that Iceberg outputs. IIRC, there is an undocumented trick to do this prior to flat package. This would require to look in the list archives. Anyway, considering it's only one file, whatever the format is, a possible solution is to go with a distribution script or a metapackage. You create a specific package for this file. You set an installation requirement so that the package will not install if the file is already there. This email sent to site_archiver@lists.apple.com
