Public bug reported:

Binary package hint: network-manager

Ubuntu release: Jaunty
NetworkManager : 0.7.1~rc4.1.cf199a964-0ubuntu2

When I unplug/plug my PC on my DHCP network, sometimes I don't get the
same IP, even if the IP is free.

The problem is that when deactive an interface, NM delete the
/var/lib/dhcp3/dhclient-<interface>.leases file ! Doing this, it's
impossible for dhclient to ask for the _same_ IP address when the
interface is re-activated.

It's a really annoying bug when you have to manage a network of Jaunty
machines : all IP addresses can change if you just reboot a switch
(deactive/reactive signal on all interfaces)... If /home is NFS-mounted,
all PC just stop to work.

The patch included fix this issue. It's from the NM git, see the commit here :
http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=756bc704029050af94ef678bb4c0bdc02da14034

Thanks
