  - Fix legacy action scripts to pass on command line     arguments.

  - Remove ntp.1.gz, it wasn't installed anymore.

  - Remove ntp-4.2.7-rh-manpages.tar.gz and only keep     ntptime.8.gz. The rest is partially irrelevant,     partially redundant and potentially outdated     (boo#942587).

  - Remove 'kod' from the restrict line in ntp.conf     (boo#944300).

  - Use ntpq instead of deprecated ntpdc in start-ntpd     (boo#936327).

  - Disable chroot by default (boo#926510).

  - Enable ntpdc for backwards compatibility (boo#920238).
