[Pkg-utopia-maintainers] Bug#611742: n-m activates IPv6 autoconf despite IPv6 Mathod "ignore"

[Michael Goetze]

Package: network-manager
Version: 0.8.1-6

Before: network-manager and nm-applet are running, but no networks are
connected.

% sysctl net.ipv6.conf.all.autoconf
net.ipv6.conf.all.autoconf = 0
% sysctl net.ipv6.conf.wlan0.autoconf
error: "net.ipv6.conf.wlan0.autoconf" is an unknown key
% ip -6 r
% ip -6 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

Action: I connect to a wireless network via nm-applet. In the
configuration of this network, the IPv6 Configuration Method is "Ignore".

After: I have a bunch of non-working IPv6 routes from stupid Apple
devices, e.g.

% sysctl net.ipv6.conf.wlan0.autoconf = 1
net.ipv6.conf.wlan0.autoconf = 1
% ip -6 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436
    inet6 ::1/128 scope host

Basically I am forced to manually disable autoconf and flush IPv6 routes
after every connection to this network.
