This problem still persist on Ubuntu 14.04.1, as follows:

Disabling IPv6 autoconfiguration in sysctl.conf doesn't affect boot
Status in “linux” package in Ubuntu:
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.
