Title:
  ifupdown calling dhclient with -1 causes it to fail when dhcp server
  unavailable

Status in “isc-dhcp” package in Ubuntu:
  Triaged

Bug description:
  Present in the Precise version (0.7~beta2ubuntu8) at least:

  ifupdown is hardcoded to call dhclient with -1, which causes it to exit on the first failure.
  This can happen in two ways:
  1) Failure to bring up the interface if the dhcp server doesn't respond in time (default 60s).
  2) Failure to renew if the dhcp server was unavailable during a previous renewal try.

  This is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=694541 as
  well, it seems.
