I am using the device in a v6 environment which works out of the box. I tried to sysctl set use_tempaddr for temporary dynamic addresses by creating a file /etc/sysctl.d/privacy-v6.conf:

but disabling/enabling wlan and either rebooting the device does not set up a temporary address. Does this work anyhow or is some other job overwriting the settings (like network manager does on some systems)?
