>Things like USB, firewire, and fibre channel allocate their device ids >on the fly. There is no such thing as a fixed device id in those cases. Also good old ATA and parallel SCSI. These are more stable than the ones where you routinely plug stuff in and out, but still the device numbers are chosen at each boot, typically according to order of discovery so that if a different set of devices is operational at boot time, the device numbers of the disk devices will be different. There's also the issue of moving a device -- medium and all -- to a different place in the configuration and moving a filesystem from one device to another. -- Bryan Henderson IBM Almaden Research Center San Jose CA Filesystems - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
