For me,  dpkg -S /etc/network/if-down.d/* returns:
resolvconf: /etc/network/if-down.d/resolvconf
ifupdown: /etc/network/if-down.d/upstart
wpasupplicant: /etc/network/if-down.d/wpasupplicant

It's a fresh 12.04.1 install on qemu-kvm with 2 network interfaces

  We only have this issue when a vm has multiple network cards assigned.
  When we do a manual "/etc/init.d/network stop; halt", the vm shuts down like expected.

  dpkg -l | grep ifupdown
