hiya > pdiff remains an unknown option though.
pdiffs are differential updates to the package database. If you intend to update your mirror on a daily base then you should keep these activated. However if you intend to update you mirror maybe only once a month then deactivating these could result in faster processing. Think of pdiffs as applying patches to your local repository information instead of refetching Release.gz with every apt-get update. Normally you'd (de)activate pdiffs via apt-conf. I don't know if mkdebmirror honors this file or not. tschüß thomas
