Bug Description

The nfs-kernel-server init script disables NFSv3 support when the rpc.nfsd daemon was bound to a specific IP address other than 127.0.0.1 or localhost using the --host <IP> argument.

Steps to reproduce:
1) Edit /etc/default/nfs-kernel-server and bind rpc.nfsd to a specific IP address:
# Options for rpc.nfsd.
RPCNFSDOPTS="--host 192.168.1.XYZ"

2) Restart the NFS kernel daemon service
service nfs-kernel-server restart

3) The rpc.mountd has NFSv3 disabled
ps -C rpc.mountd -o cmd
/usr/sbin/rpc.mountd --port 32767 --no-nfs-version 3

The problem happens in the /etc/init.d/nfs-kernel-server init script on line 115-116 during the rpcinfo check:
$PREFIX/bin/rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

This bug was fixed in the package nfs-utils - 1:1.2.8-6ubuntu1

---------------
nfs-utils (1:1.2.8-6ubuntu1) trusty; urgency=medium

  * Merge from Debian unstable, remaining changes:
    - debian/nfs-common.{statd,statd-mounting,gssd,idmapd}.upstart,
      debian/control, debian/nfs-common.{preinst,postinst,prerm,postrm},
      debian/rules: drop nfs-common init script in favor of upstart jobs.
    - Depend on rpcbind (>= 0.2.0-6ubuntu1) for upstart support.
    - Depend on mountall (>= 2.41) to avoid deadlocks on boot.
    - debian/nfs-common.default: always start idmapd automatically; drop
      the configuration option.
    - nfs-kernel-server.init: Unmount nfsd fs when init script stops
    - Allow issuing options to rpc.nfsd
    - Add "-e" (ticket expiry is error) option to rpc.gssd to prevent hangs
      due to EKEYEXPIRED error from kernel on ticket expiry.

nfs-utils (1:1.2.8-6) unstable; urgency=medium

  * Fix the sec=krb5* handling in debian/nfs-common.init to properly match
    all cases. Closes: #715478.
  * Move the rpc.svcgssd(8) symlink to nfs-common along with the rest of it,
    and add the Replaces: on old versions of nfs-kernel-server to support
    upgrades properly. Closes: #731479.
  * Only start nfs-common in runlevel S; it doesn't need to be started
    more than once (and startpar won't actually run it more than once,
    anyway). Closes: #510528.
  * Fix obsolete invocations of update-rc.d by switching nfs-common to use
    dh_installinit. Closes: #736059.
  * Tweak nfs-common preinst to not remove nfs state files except on package
    removal (i.e., these should not be removed when the package is
    deconfigured temporarily).
  * debian/nfs-kernel-server.init: don't try to check for nfsv3 configuration
    in nfsd and pass --no-nfs-version 3 to mountd if absent; the check is
    buggy and impossible to make reliable, and there's no reason to single
    out NFSv3 here (and the original rationale for this behavior is lost).
    Closes LP: #897644, LP: #1284210.
  * Provide quoted entries by default in debian/nfs-kernel-server.default,
    consistent with other default files, so that users who edit the file to
    add multiple options don't accidentally cause shell syntax bugs.
