I use /etc/network/interfaces for the static IP and tell the kernel
via sysctl to accept Router-Advertisements for additional prefixes
(autoconf=1 and accept_ra=1) under which it should generate random
addresses (use_tempaddr=2). New IPv6 Adresses then appear magically
with scope "global temporary dynamic".
My DNS servers are configured fixed in /etc/resolv.conf.
There is no radvd or dhcp6d running.

iface eth0 inet6 static
    address 2001:4dd0:0:xxx:yyy::
    netmask 64
    gateway fe80::1
    pre-up sysctl net.ipv6.conf.eth0.autoconf=1
    pre-up sysctl net.ipv6.conf.eth0.use_tempaddr=2
    pre-up sysctl net.ipv6.conf.eth0.accept_ra=1
