Incorrectly messaging "Starting/Stopping NTP server" in ifup/ifdown scripts

Binary package hint: ntp

When I so some action with network interfaces, NTP messages interrupt my console output, after command promt returned. If ntp server doesn't start very fast, the messages can be mixed with the output of next commands for example.

root@ruclen:~# ifdown eth0; ifup eth0
 * Stopping NTP server ntpd
   ...done.

root@ruclen:~# //continue working
root@ruclen:~# //continue working
root@ruclen:~#
root@ruclen:~# * Starting NTP server ntpd
   ...done.

I suppose the bug is in /etc/network/if-up.d/ntpdate scrpit
