At least with Fedora 14, I can confirm that you can enable rfc3401 privacy by
adding the respective option in the /etc/sysctl.conf.   e.g.

echo net.ipv6.conf.eth0.use_tempaddr=2 >> /etc/sysctl.conf

presumably you could specify all devices with:

echo net.ipv6.conf.all.use_tempaddr=2 >> /etc/sysctl.conf



You can enable it at runtime per device via:

ifdown eth0
sysctl net.ipv6.conf.eth0.use_tempaddr=2
ifup eth0


This to me seems much better than setting an option inside an ifcfg file.
