Public bug reported:
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.
