Comment 10 for bug 990011

It doesn't overrule it. Please make sure you set net.ipv6.conf.default.use_tempaddr to 0 in 10-ipv6-privacy.conf (or in /etc/sysctl.conf, etc.) if you want it to not be set. Alternatively, you may want to set "ip6-privacy=0" in the configuration file for your connection (under /etc/NetworkManager/system-connections/).

This isn't changing the value in a default release. The issue was that for default automatically generated connections for wired devices, NM was trying to be clever and reading a file we don't actually keep the ipv6 use_tempaddr setting in, and thus always setting it to 0.

If you're running into problems with this, please make sure you file a separate bug and define all the information specific to your system, such as what is set in /etc/sysctl.conf and /etc/sysctl.d/10-ipv6-privacy.conf, as well as whatever connection file might be relevant (in case the values are set in there). Then refer to your new bug here so we can look into it ASAP.
