I tried to set use_tempaddr for ipv6 privacy IPs (temporary global addresses) by creating /etc/sysctl.d/privacy-ipv6.conf:
net.ipv6.conf.all.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2
net.ipv6.conf.wlan0.use_tempaddr=2
but sysctl -p this file, echo the parameters directly in /sys... and reboot does not work. Is there something missing?

This is done by connman: edit your wlan settings in /var/lib/wifi_xxxx/settings (devel-su):
IPv6.privacy=prefered
Disconnect and connect and you have a global temporary dynamic address. But there is another question: why is IPv6.privacy in a non ipv6 network prefered and in a ipv6 network disabled by default?
could be also "preferred" see https://lists.connman.net/pipermail/connman/2013-August/015535.html

My opinion: huh? My solution: Running the following command after a new network connection (= connman service) has been added:
sed -e's,^IPv6.privacy=.*,IPv6.privacy=prefered,' -i /var/lib/connman/*/settingsNeeds to be run as
root, e.g. in a script executed via sudo. See that question for ways to quickly execute short shell commands:

)edithmm - I tried the above and it works ok for (I think) the first temporary address, but once that expires then I don't get another temporary address and it falls back to the MAC address based global address. While taking the interface up and down (via CLI or settings UI) does get me a new temporary addr that seems unusable. Any idea how to ensure a continual stream of temporary addresses?

This should be default, right?
