Hi,
There is a forward-compatibility bug in nbd-client <= 3.9, in that it
incorrectly merges two flags fields when sending flags to the kernel.
The result of this bug is that all exports exported by nbd-server >= 3.9
and connected to by nbd-client <= 3.9 are all marked as read-only on the
client side.
I would like to update the package in Jessie to remedy the issue, so
that upon the release of Stretch, clients running Jessie can still talk
to servers running Stretch.
