netcfg (1.62ubuntu1) oneiric; urgency=low

  * Resynchronise with Debian. Remaining changes:
    - Set default hostname to 'ubuntu'.
    - Drop priority of netcfg/get_domain to medium for non-static
      configurations.
    - Use 'auto <interface>' for all interfaces, dropping allow-hotplug
      which doesn't work with current udev.
    - Call /usr/lib/network-manager/ifblacklist_migrate.sh from
      finish-install if present, so that 'auto dhcp' interfaces are disabled
      if network-manager is in use. May be preseeded away with
      netcfg/network-manager.

So it's really an issue in network-manager, seems like we're dropping ifblacklist_migrate.sh now.
