Bug#709403: nfs-kernel-server: all exports are read only

[Dmitry Smirnov <onlyjob@member.fsf.org>]

Package: nfs-kernel-server
Version: 1:1.2.8-2
Severity: important

Upgrade of nfs-kernel-server from 1:1.2.6-3 to 1:1.2.8-2 turned all my
NFS exports to read-only.

Before upgrade `sudo exportfs -v` show something like

    /root.nfs/r3    192.168.0.0/24(rw,root_squash,all_squash,no_subtree_check,mountpoint,anonuid=1000,anongid=1000)

but after upgrade it is 

    /root.nfs/r3    192.168.0.0/24(ro,root_squash,all_squash,no_subtree_check,mountpoint,anonuid=1000,anongid=1000)

even though there were no changes to /etc/exports.
I can't make any of my NFS exports writable without downgrading
"nfs-kernel-server" and corresponding "nfs-common".

Please advise. Thanks.

Cheers,
 Dmitry Smirnov
