Title:
  Disabling IPv6 autoconfiguration in sysctl.conf doesn't affect boot
  process

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When you put the following lines in sysctl.conf

  net.ipv6.conf.all.autoconf = 0
  net.ipv6.conf.all.accept_ra = 0

  the expeced result is to disable IPv6 autoconfiguration at bootup,
  but, actually, it does nothing, because sysctl.conf network settings
  are applied after network has been started.

  So what happens:
  1. Network interfaces are started by /etc/init.d/networking
  1a. IPv6 uses autocnfiguratin, because it is enabled at this point
  2. Sysctl.conf settings are applied by /etc/init/procps.conf

  I don't know if there is an easy solution, because inverting order
  things are called could break something else.
