It's like the /dev/ttyS* and /dev/cua* situation, where we also ended up with multiple device files. This is bad.
SG_IO-on-hdx is modern. It properly associates everything with one device, which you may name as desired.
sg0 is useful for devices that are not disk, tape, or CD. A decade ago, it was also the proper way to send raw SCSI commands to other devices. For nasty compatibility reasons, Linux still assigns /dev/sg* devices for disk, tape, and CD. - 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/
