Comment 4 for bug 1023174

Uploaded a new isc-dhcp working around the issue in the debian-installer case. A debian-installer upload will be needed to get this workaround included.

dhclient will still try to run "ip -6 addr flush" in some DHCPv6 cases so this is still a important to get this fixed soon before IPv6 becomes more popular and people start noticing their connectivity vanishing when dhclient exits.
