When adding or modifying a printer, cupsd accepts an attached file (typically a PPD file) to use for the printer. Previously cupsd examined the file - PPD files were copied to the ServerRoot/ppd directory while all other files were treated as interface scripts and copied to the ServerRoot/interfaces directory and given execute permissions.
