    - Create user/group dhcpd and make isc-dhcp-server depend on adduser.
    - Create /etc/dhcp/ddns-keys/ for DDNS updates.
    - Sanitize environment in dhclient-script.linux.
    - Add systemd units for -server and -relay.
      + If /etc/ltsp/dhcpd.conf exists, use that instead of
        /etc/dhcp/dhcpd.conf.
    - isc-dhcp-server: Suggest policycoreutils instead of recommending it.
    - ipv6: wait for duplicate address detection to finish. LP #1633479
    - Ship dhcp exit hook to push DNS information to resolved. LP #1889068

    - Disable make_resolv_conf() if systemd-resolved is in use.
    - debian/control: add Pre-Depends: ${misc:Pre-Depends} for
      init-system-helpers.
    - debian/apparmor/sbin.dhclient: Allow disabling dhclient hooks.
    - Do not build with DH_VERBOSE=1
  * Dropped changes, included in Debian:
    - Ship keama, the KEA Migration Assistant in a new isc-dhcp-keama binary
      package. (LP: #2020086)
  * Refresh patches (using gbp pq)
  * debian/control: Drop libcap-dev build dependency (no change in diffoscope).
  * Use /run/dhcp-server6 for isc-dhcp-server6 service.
    Thanks to Jason Penney (LP: #1543799)
  * debian/rfc3442-classless-routes.linux: Use configured metric.
    Thanks to Tom Carroll (LP: #1664352)
  * autopkgtest: Use setup logic from isc-dhcp-server.service

Title:
  dhclient-script doesn't use configured metric for rfc3442 classless
  routes

Status in isc-dhcp package in Ubuntu:
  Fix Released
Status in isc-dhcp package in Debian:
  New

Bug description:
  lsb_release -rd
  Description:	Ubuntu 16.04.2 LTS
  Release:	16.04
  apt-cache policy isc-dhcp-client
  isc-dhcp-client:
    Installed: 4.3.3-5ubuntu12.6
    Candidate: 4.3.3-5ubuntu12.6
    Version table:
   *** 4.3.3-5ubuntu12.6 500
          500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
          100 /var/lib/dpkg/status

  If the metric option is set in interfaces(5), dhclient is executed
  with the variable IF_METRIC set to the configured administrative
  metric. The exit-hook rfc3442-classless-routes doesn't use the
  variable; thus, a multi-interface box will experience a race condition
  if multiple interfaces are supplied with one or more duplicate rfc3442
  routes. The attached patch adds support for IF_METRIC handling.
