What you > mean is CONFIG_SCSI_DRIVERS_WHICH_APPEAR_IN_THE_SCSI_MENU. when I said "driver" I meant more along the line of SCSI hardware instead of things that use the "Linux" scsi subsystem. i.e. usb, sata are not scsi hardware even though they use the scsi subsystem. Or to put it another way, perhaps no "select"able option should ever be visibly selectable in XYZconfig. And XYZconfig should only show an option that is "select"able if by selecting it one ends up with a consistent configuration. So you have a "virtual" SCSI_SUBSYSTEM which usb-storage, sbp2, sata all pull in by selecting it. you have SCSI_HARDWARE that adaptec, buslogic, lsilogic...... depend on. SCSI_HARDWARE would also select "SCSI_SUBSYSTEM". - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
