Status changed to 'Confirmed' because the bug affects multiple users.

Relevant citation is http://tools.ietf.org/html/rfc3442#page-4, "Local subnet routes" -- this behaviour should work and this script currently does not correctly implement RFC 3442.

---------------
isc-dhcp (4.2.4-1ubuntu1) quantal; urgency=low

  * Merge from Debian. Remaining changes:
    (LP: #768171, LP: #841182, LP: #881558, LP: #872929, LP: #616809)
    - Use upstart jobs for isc-dhcp-server and isc-dhcp-relay.
    - Add IPv6 support to udeb dhclient-script (forwarded as Debian #635897).
    - Add an apport hook to isc-dhcp-client and isc-dhcp-server.
    - Add an apparmor profile to isc-dhcp-client and isc-dhcp-server.
    - Update default dhclient.conf to ask for IPv6 configuration.
    - Patches:
      + dhclient-fix-backoff
      + dhclient-more-debug
      + dhclient-onetry-call-clientscript
      + dhclient-safer-timeout
      + dhcpd.conf-subnet-examples

  * Set fqdn.fqdn to the result of gethostname(); (LP: #991360)
  * Replace old droppriv and deroot patches by use of --enable-paranoia
    and matching -user and -group parameters to dhcpd. (LP: #727837)
  * Allow read access to /etc/dhcp/ddns-keys/* for ddns. (LP: #341817)
    It's expected that people generate one key per zone and have it stored
    in both /etc/bind9 and /etc/dhcp/ddns-keys/ for security reason.
  * Fix apport hook to work with python3.
