We've been shipping those two hooks for a while in Ubuntu. Yesterday I reworked them to use the new environment variables and avoid hardcoding any path that we have available as a variable. I tested both to work on Ubuntu 13.04 but they should work just as well on any distro shipping with the cgroup hierarchy in /sys/fs/cgroup and with ecryptfs available. Those are intended as example and distros are free to drop them, they should however be working without any change required, at least on Ubuntu.
