/etc/init.d/ntp was being run twice on Ubuntu14 (and was failing slowly
the first time) because of the presence of
/etc/network/if-up.d/ntpdate... which would run ntpdate then
/etc/init.d/ntp via invoke-rc.d... so we would see a double start with
lots of delay.

So now we overwrite that hook script!  Ugh.
