Public bug reported:

Steps to reproduce:
(deinstall networkmanager and) setup network interface to use dhcp  (like  auto eth0; iface eth0 inet dhcp)
unplug the network cable from the interface (eth0 in this case)
boot

expected result:  system skips interface configuration and gives error immediately, because  no link is NO LINK.
actual result: Boot hangs for something like 4 minutes, waiting for the cable to levitate to the socket magically.

** Affects: ifupdown (Ubuntu)
     Importance: Undecided
         Status: New
