When running a rootless container, how can one identify the cgroup in use from inside the container? /proc/self/cgroup is "0::/", but the "real" cgroup is something like "user-1000.slice/user@1000.service/user.slice/libpod-7126f828cd4389ca0a9e29a94e78af39c91f51f3f892a799cb7f3eeff067d1bd.scope/container". One hacky way to find it out is to look at /run/.containerenv and get the container id there, then to look for a directory in /sys/fs/cgroup named libpod-$containerid.scope, but is there a more straight forward one? In the end I would like to be able to read "memory.max" and "memory.current" in the cgroup dir.
