+stable_secret - IPv6 address
+ This IPv6 address will be used as a secret to generate IPv6
+ addresses for link-local addresses and autoconfigured
+ ones. All addresses generated after setting this secret will
+ be stable privacy ones by default. This can be changed via the
+ addrgenmode ip-link. conf/default/stable_secret is used as the
+ secret for the namespace, the interface specific ones can
+ overwrite that. Writes to conf/all/stable_secret are refused.
+
+ It is recommended to generate this secret during installation
+ of a system and keep it stable after that.
+
+ By default the stable secret is unset.
