I think Eric's point is that dropping oldstyle in qemu-nbd isn't
really a problem because nbdkit has no plans to drop oldstyle. So
there will remain a path for very old clients to keep working (whether
using nbdkit natively, or using nbdkit to proxy to qemu-nbd). Eric's
example used the more complex proxy case. By contrast the nbdkit
native case is very simple:
nbdkit -o file disk.img
(where the ‘-o’ flag switches to oldstyle protocol).
Rich.
