  server DSA and ECDSA certificates.
  - update ntpd/ntp_crypto.c to properly check the return code of
    EVP_VerifyFinal()
  - CVE-2009-0021

11. By Adam Conrad

Call dh_installinit with --error-handler=true, which will prevent
ntp-server's prerm and postinst from bombing out on upgrades from
previous broken versions. ntp-{simple,refclock} still try to
restart the server in their postinst, so it won't be left dead.

10. By Adam Conrad

Attempt to create the ntp user in ntp-server's postinst, as the
dependency loops between ntp-server and ntp-means we have no
way of knowing which gets configured first (launchpad.net/33351)

9. By Scott James Remnant (Canonical)

Hide output from ntpdate unless ifup is run with -v.

8. By Scott James Remnant (Canonical)

Ignore errors from ntpdate, otherwise the interface might not come
fully up.

7. By Scott James Remnant (Canonical)

Remove ntpdate init script, instead install a script in
/etc/network/if-up.d that sets the clock whenever we bring up a network
interface.

6. By Colin Watson

* Resynchronise with Debian.
* Use ntp.ubuntu.com rather than ntp.ubuntulinux.org.

5. By Fabio Massimo Di Nitto

Fix error message in ntp-server init script.
(Closes: #14726)
