* Resynchronise with Debian. Remaining changes: - Set default hostname to 'ubuntu'. - Set priority for get_domain to high for static configurations. - Set priority for get_domain to medium for non-static configurations. - Use 'auto <interface>' for all interfaces, dropping allow-hotplug which doesn't work with current udev. - Set DHCP and DHCPv6 timeout to 30s. - Use isc-dhcp-client-udeb on all architectures. - Flush all addresses and routes before configuring interfaces (LP: #848072) - Don't copy /etc/resolv.conf to target if resolvconf is installed. (We already write resolvconf configuration to /etc/network/interfaces.) - Add a post-base-install hook to detect resolvconf and copy /run/resolvconf/resolv.conf to outside the target so that when /run is bind-mounted DNS resolving continues to work. (LP: #926447) - Apply patch from Alec Warner making netcfg respect netcfg/dhcpv6_timeout and running dhclient in one-shot mode (-1). (LP: #917905) - Fix FTBFS by checking the return value of fgets and fscanf. - Fix nm-conf to generate a valid NetworkManager static configuration file. - Always allow fe80::/64 for the default gateway. (LP: #1382295)
