Title:
  Unplugged or deactivated ethernet interfaces may not be handled
  properly

Status in “ifupdown” package in Ubuntu:
  New

Bug description:
  If i have a server which has a management-only interface which is
  usually down, in versions of Ubuntu before 11.10, I could configure
  that ethernet interface in /etc/network/interfaces, and dhclient would
  try forever to get an address.

  I believe this is a regression that was introduced in the fix for bug
  #838968 , where the '-1' parameter was introduced to dhclient3's
  invocation in ifupdown.

  While I do think we should report errors, we should also retry this
  *forever* since it may be the only way a system can be reached *to see
  that error*.
