+ * friendy name -> filename.  If the prefix is not empty, then
+ * the prefix will be applied to the filename.
+ *
+ * The friendly names that this function will currently fill in are:

+ *   PRIVATE_KEY

+ *   PERMISSIONS

+ * \param[in]  supports_pkcs11 Whether the RMW has support for PKCS#11 URIs.
