To force the AppleShare PDS files for volumes to be created in the System Folder: Preferences: File Server folder instead of invisible on the volume, create a folder on the volume called AppleShare PDS. When AppleShare tries to create the PDS file on the volume it won't be able to. It will then create a visible 'volume name PDF' file in the File Server folder. It will now be easier to back up and keep track of the permissions files.
