[systemd-devel] systemd-networkd: option for IPv6 privacy extension?

[Ansgar Burchardt]

Hi,

I'm wondering if systemd-networkd could provide an option to control the
IPv6 privacy extension? It is controlled via a sysctl setting:

  net.ipv6.conf.${interface}.use_tempaddr

with three values:

  <= 0 : disable Privacy Extensions
  == 1 : enable Privacy Extensions, but prefer public
         addresses over temporary addresses.
  >  1 : enable Privacy Extensions and prefer temporary
         addresses over public addresses.

    -- Documentation/networking/ip-sysctl.txt

It would be nice if systemd-networkd would allow to control these
options, for example by a "IP6Privacy" setting in the Address section of
.network units (NetworkManager already uses "ip6-privacy").
