Well, but anyway.  Just as I didn’t have anything against adding QMP to
qemu-nbd, I don’t have anything against adding a new application that
kind of fulfills the same purpose.  And I think introducing a new
application instead of reusing qemu-nbd that focuses on all-around QAPI
compatibility (which qemu-nbd decidedly does not have) makes sense.

Yes, QAPI is one big reason for creating a new tool that doesn't need to
support the old qemu-nbd command line. Another is that we can add other
types of exports that are not NBD.

If we could make qemu-nbd a thin wrapper around the new tool (even if the two are not necessarily command-line compatible), that might be worthwhile.

The only thing I don’t like is the name, but that’s what <Tab> is for.

I'm open for suggestions, but I thought 'qsd' was a bit too terse. :-)

(Actually, maybe we could even pick something that doesn't mention
storage or block? After all, it can do all kinds of QEMU backends in
theory. Not sure if there's any standalone use for them, but who

Maybe 'qback', for qemu-backend?
