描述

Unfortunately, the cgroup hierarchy is located at /cgroup on centos6, and the current source hard-assumes a location of /sys/fs/cgroup.

I've been going over the rkt source, and it isn't clear to me at first glance which parts of the source are being used by the host and which the guest. I think that since a lot of stage1 is shared source, and given that systemd wants cgroup in /sys/fs, it's not a clear migration.

For anyone interested in running rkt on centos6, I have a working flock-based patch at https://github.com/coreos/go-iptables/pull/11. (For some reason travis doesn't like it, but I can build rkt cleanly with that repo!)

研究方向
Investigate the rkt source code to identify all locations where the cgroup path is hardcoded to /sys/fs/cgroup. Consider the distinction between host and guest code as mentioned in the issue. Review the linked patch in go iptables for a potential approach. Propose a solution that either detects the correct path at runtime or makes it configurable.
