I confirm this. IPv6 privacy extensions were enabled by default in 12.04 (actually, I don't see this in the release notes, or in any other official documentation, but Internet search engines show "everyone" says so), and they were working in 12.10.

Testing with a fresh install of Kubuntu 13.04, my eth0 interface doesn't have a randomised address, only a link-local address, a global MAC-based address and a DHCP-allocated IPv4 address.

/etc/sysctl.conf and /etc/sysctl.d/10-ipv6-privacy.conf in 13.04 have been unchanged since 12.04.

Putting
net.ipv6.conf.eth0.use_tempaddr = 2
into 60-ipv6-privacy.conf or directly into /etc/sysctl.conf makes no difference, and even after a reboot /proc/sys/net/ipv6/conf/eth0/use_tempaddr is 0.
