  * Those option are WA for
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=600661
    WA needed for extremly rare situatuon, when network dhcp provide wrong
    ntp.
  * Those option make sence to use only with dropping 'ntp-servers' request
    from dhclient.conf - unless, you totally remove dhcp client from system
  * Misc: update  run_tests.sh to latest
