Calling the ATA IDENTIFY command a Linux ABI quirk is disingenuous.
I think ATA has earned that moniker all by itself.
Not sure what the SCSI equiv is to get a serial number (VPD?) But if everyone is happy with 20 bytes, and John wants to do SN that way, I'll take the patch.
I've been swayed from one side to the other of this argument. Still I'd begrudgingly give my vote to the ATA option only because it reuses an existing wart vs. introducing a new one. Updated qemu patch follows leveraging your virtqueue REQ_TYPE_SPECIAL scaffolding. At this point only the issue of this guest visible interface should remain. -john -- address@hidden
