Please backport isc-dhcp 4.2.4-1ubuntu10.1 (main) from quantal-updates

[Anders Rosendal]

Please backport isc-dhcp 4.2.4-1ubuntu10.1 (main) from quantal-updates to precise.

Reason for the backport:
========================
ISC DHCPD V4.2 (and later) contains the configuration directive "auto-partner-down" which is required to build an unattended redundancy solution with dhcpd. Without this function IP-Pool need to be >2x the requried size.
12.04 LTS is the aproriate choise for a production environment, although dhcpd < 4.2 might force users into upgrading HA systems to non-LTS releases.

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s quantal -d precise isc-dhcp

* precise:
[ ] Package builds without modification
[ ] isc-dhcp-relay-dbg installs cleanly and runs
[ ] isc-dhcp-relay installs cleanly and runs
[ ] isc-dhcp-dev installs cleanly and runs
[ ] isc-dhcp-client installs cleanly and runs
[X] isc-dhcp-common installs cleanly and runs
[X] isc-dhcp-server installs cleanly and runs
[ ] isc-dhcp-server-dbg installs cleanly and runs
[ ] isc-dhcp-client-udeb installs cleanly and runs
[ ] isc-dhcp-server-ldap installs cleanly and runs
[ ] isc-dhcp-client-dbg installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of isc-dhcp. For reverse-build-dependencies (-Indep), please test that the package still builds against the new isc-dhcp. For reverse-dependencies, please test that the version of the package currently in the release still works with the new isc-dhcp installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.

[danleyden (dan-52degreesnorth)]

I'm trying to set various other options (dhcp-renewal-time, dhcp-rebind-time) again as part of a HA solution, which is supported in 4.2 but not in 4.1. In order to get HA working in the way it is needed in my environment, the newer version with support for auto-partner-down and the setting of the additional options is critical
