List,

Privacy for ipv6 autoconf adressess is now enabled by default. I have no 
problem with this and believe this should remain the default going forward. 
However I am seeing some behaviour in the ipv6 stack that I am unsure of and I 
don't know if the behaviour is intentional, buggy or just not adequately 
configured.

The issue is that the ipv6 sysctl's do not seem to be parsed correctly on 
boot, or maybe the interfaces are being brought up before the config is 
parsed.

    # cat /lib/sysctl.d/sysctl.conf | grep use_temp
    net.ipv6.conf.default.use_tempaddr = 2

Immediately after boot:

    # cat /proc/sys/net/ipv6/conf/{default,all,eth0}/use_tempaddr
    2
    0
    0

This configuration will remaing until manual intervention.

After restarting network:

    # cat /proc/sys/net/ipv6/conf/{default,all,eth0}/use_tempaddr
    2
    0
    2

Which has the effect of not generating a random ipv6 address unless the 
network is restarted. All the hosts are upgraded from 11.4 so I am unsure if 
this is an issue with the parrallel nature of booting now or whether some 
remnant of the 11.4 system config is preventing the ipv6 sysctl's from being 
applied. If this is a config issue please point me in the right direction 
otherwise I'll fill a bug.
