Yes, but given my /dev/sg contains the following: lr-xr-xr-x 1 root root 39 Jul 18 22:23 c0b0t1u0 -> ../scsi/host0/bus0/target1/lun0/generic lr-xr-xr-x 1 root root 39 Jul 18 22:23 c0b0t2u0 -> ../scsi/host0/bus0/target2/lun0/generic lr-xr-xr-x 1 root root 39 Jul 18 22:23 c0b0t5u0 -> ../scsi/host0/bus0/target5/lun0/generic lr-xr-xr-x 1 root root 39 Jul 18 22:23 c1b0t0u0 -> ../scsi/host1/bus0/target0/lun0/generic It would assume I would actually need sg[0-3] would it not? So if I were to not be using DevFS how would this be setup properly? And then once that is establish'd figuring out how to emulate with DevFS for software that will not use DevFS should fall together... Would be so nice if software that uses device nodes from /dev would be able to tell the difference in DevFS or non-DevFS and handle this without need for anything more... Hey I can dream can't I?
