SLAAC private addresses and privacy extensions

Hi,

I am using Debian Sid and enabled the usage of RFC 7217 address via
'slaac private' which gives me a stable address but this is not a
temporary address, i.e. ip addr gives me

iface: [...]
  inet6 IPv6::address scope global dynamic mngtmpaddr noprefixroute
    valid_lft 300sec preferred_lft 60sec

Since RFC 4941 is supported, is there also a way, to get temporary
addresses managed by dhcpcd or do I have to enable it with setting

"net.ipv6.conf.all.use_tempaddr = 2"

with possibly setting also the preferred and maximum valid lifetime via
sysctl and then that part is handled by the kernel?


Cheers,
Julian
