Doing conditionals based on a driver name in core code is a real maintainance hurden over the long term as it breaks the abstraction. I'd prefer the method call, but the other options would be to add a flags field to the driver structure and then defined a flag for the epoch/data layout which gets set by the simple driver. -- sheepdog mailing list [email protected] http://lists.wpkg.org/mailman/listinfo/sheepdog
