[ UNIX only] It is possible to remove all keyfile protection from the delivered application by specifying :product-code :none . If you do this, a check is made during the delivery process to ensure that you have in addition to a LispWorks Delivery key, a key for LispWorks Delivery PLUS. If you do not have this key then your image will exit immediately when the check fails. Therefore you should only specify :none as your product code if you have made a prior arrangement with Xanalys to do so.
You may wish to make your own security arrangements or you may choose to leave the run-time image totally unprotected. Although an unprotected run-time application will not require any keys (even for any layered products which were loaded into it before delivery), it may still be subject to time-expiration.
