[Bug 1556447] Re: lxc-start fails: lxc_cgfsng - cgfsng.c:all_controllers_found:430 - no systemd controller mountpoint found

The systemd cgroupfs is mounted under /sys/fs/cgroup/systemd.  Your current
login path can be found with

awk -F: '/systemd/ { print $3 }' /proc/self/cgroup

so

pwd=/sys/fs/cgroup/systemd/`awk -F: '/systemd/ { print $3 }' /proc/self/cgroup`
sudo -E chown $(id -u):$(id -g) $pwd

should work
