I suspect it may have something to do with the issue.
I don't know what elementary freya is, but maybe this is a bug in the systemd package there. Get the cgroxy logs (start it with --debug), and see what calls are being made to it. Better yet strace the login process (maybe start with the getty or sshd). If it is reading the cgroup path from /proc/self/cgroup and then using cgmanager to movepid to something based on that, that's wrong. _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
